AB  - Organobentonites have been applied for the removal of two common non-steroidal anti-inflammatory drugs, ibuprofen (IBU) and diclofenac sodium (DS), from aqueous solutions. Two surfactants, one with and the other without benzyl group (octadecyldimethylbenzylammonium chloride, ODMBA, and hexadecyltrimethylammonium bromide, HDTMA), in amounts equivalent to 50, 75, and 100% of the cation exchange capacity of bentonite were used for the preparation of organobentonites. Successful modification of bentonite was confirmed by several methods: X-ray powder diffraction (XRPD), point of the zero charge (pHPZC), determination of exchanged inorganic cations in bentonite, determination of textural properties, and scanning electron microscopy (SEM). Kinetic and thermodynamic data on the adsorption of IBU and DS showed that drug adsorption was controlled by the type and the amount of surfactant incorporated into the bentonite and by their arrangement in the interlayer space and at the surface of organobentonites. The adsorption of both drugs increased with an increase in the amount of both surfactants in organobentonites. The presence of the benzyl group in organobentonites enhanced the adsorption of IBU and DS and was more pronounced for IBU. Drug adsorption fits the pseudo-second-order kinetic model the best. The thermodynamic data revealed that the adsorption process was endothermic in nature and with increase of the amount of both surfactants drug adsorption processes were more spontaneous. The results obtained from this study revealed that adsorbents based on surfactants modified bentonite are promising candidates for IBU and DS removal from contaminated water.

AB  - One of the most interesting secondary raw materials within the Kolubara Basin is diatomaceous earth or diatomite, with reserves of 308.670 t in fields B and C. Chemical and mineralogical tests were performed on diatomaceous earth samples. The results of these tests are presented in this paper. Diatomite is a soft sedimentary rock formed by the deposition of cell walls (frustulae) of single-celled algae-diatoms at the bottom of sea and lake basen. Diatom frustules consist of two parts that lie on top of each other and represent a highly porous skeleton of amorphous hydrated silica. Diatom frustule size ranges from 1 μm to 1 mm, usually 10-200 μm.The specific area (SBET (m2/g)) is 47.6. The SEM/EDS, BET and FTIR methods were used for characterization. Based on the presented results, diatomaceous earth can be used in the pharmaceutical, ceramic and food industries.

AB  - Magnetic iron oxide nanomaterials, which enable a multitude of uses, are given special focus in the fields of biomedicine and environmental protection. The detection, sorption, and/or degradation of inorganic (lead, chromium, arsenic, and cadmium), organic (dyes, pharmaceuticals, pesticides, phenols, and benzene), and biological (viruses and bacteria) pollutants can all be effectively accomplished with the use of magnetic nanoparticles. Magnetic iron oxide nanomaterials are in particular focus for use as hyperthermia media in cancer treatment and as magnetic resonance imaging (MRI) contrast agents. The possibility of magnetic separation of such materials, due to their essential properties under the influence of an external magnetic field, reduces production costs and also prevents the production and accumulation of toxic waste. Among the many metal oxide nanomaterials, magnetite (Fe3O4) and maghemite (γ-Fe2O3) are currently the only two magnetic materials approved by the US Food and Drug Administration (FDA) for human use as iron deficiency therapeutics and as contrast agents for MRI. Here, we synthesized nanoparticles of magnetite (Fe3O4) by the method of reduction-precipitation and characterized. Additionally, potential binding of brilliant green dye on Fe3O4 and construction of innovative magnetic composite was investigated. The physicochemical features were explored using X-ray diffraction (XRD), 
Fourier-transform infrared spectroscopy (FTIR), and field emission scanning electron microscopy (FESEM). XRD analysis confirms formation of the crystal phase of magnetite. The presence of magnetite nanoparticles is shown by typical groups for the peaks of iron compounds at a lower wavelength (≤ 700 cm-1) that are characteristic of the Fe-O bond. Morphological analyzes with FESEM showed that magnetite is a composite of nanospheres and nanorods that provide a large surface area. Dye binding study was performed using UV visible and FTIR spectrometer.

AB  - Two medium-carbon microalloyed steels with a predominant acicular ferrite microstructure were investigated in this study in order to determine the initial micro-crack formation mechanism and the role of acicular ferrite structure in cleavage fracture. In order to ensure cleavage fracture, samples were investigated at −196 ◦C for uniaxial tension and four point bending fracture. Previous investigations have shown that cleavage fracture for steels with a predominant acicular ferrite microstructure has not been initiated by the fracture of coarse TiN particles as in ferrite-pearlite,
bainite, or martensitic microalloyed steels. The average maximal thickness of cementite plates measured in this work is 0.798 µm and 0.966 µm, for V and TiV steel, respectively. The corresponding stress values required for their fracture according to Griffith’s equation are 1970 MPa and 1791 MPa,
respectively. Estimated values of the effective surface energy for the V steel with an average cementite volume fraction of 3.8% range from 40 Jm−2 to 86 Jm−2, and for the TiV steel with an average cementite volume fraction of 18.3% range from 55 Jm−2 to 82 Jm−2. The fracture of coarse cementite plates was found to not to be responsible for the cleavage fracture initiation in case of both steels.

AB  - In order to study the effect of Zr doping on the thermoelectric properties of p-type Bi10.17Sb30.72 Zr0.35Te58.28Se0.48 single crystal, аn ingot was prepared by Bridgman method. Cut and cleaved samples from different regions of ingot were characterized by a Hall Effect based on the Van der Pauw method. The first measurements were conducted with four ohmic contacts at room temperature and the obtained results were presented in our investigation, earlier. Аlso, high charge carriers mobility was obtained on the sample with silver contacts at the temperature of liquid nitrogen.

abstract = "In order to study the effect of Zr doping on the thermoelectric properties of p-type Bi10.17Sb30.72 Zr0.35Te58.28Se0.48 single crystal, аn ingot was prepared by Bridgman method. Cut and cleaved samples from different regions of ingot were characterized by a Hall Effect based on the Van der Pauw method. The first measurements were conducted with four ohmic contacts at room temperature and the obtained results were presented in our investigation, earlier. Аlso, high charge carriers mobility was obtained on the sample with silver contacts at the temperature of liquid nitrogen.

AB  - Antina Čuka listvenite originated by hydrothermal alteration of small ophiolite mass caused by Paleogene magmatic activity. Mineralogical and petrological examination of the listvenite revealed serpentine-rich, silica-rich, and carbonate-rich varieties of the listvenite. Typical minerals are serpentine (group), carbonates (calcite, dolomite, and magnesite), pyrite, gersdorffite, Cr-spinel, barite, limonite, and native Ag. Gemological analysis revealed all serpentine varieties from Antina Čuka (serpentine-rich listvenite, serpentine-rich listvenite with magnetite and fresh serpentinite) have values of both refractive index and specific gravity in the range for serpentine group minerals. A Refractive index value of 1.54 for silica-rich variety confirms the presence of quartz. The results of lapidary processing have proven that both listvenite from Antina Čuka and serpentinite host rock are attractive gemstones. The adequate types of processing of Antina Čuka listvenite are plain cut (different-shaped cabochons) and glyptography/carving.

AB  - This study investigates the electrochemical stability of the gold complex based on mercaptotriazole at an optimum pH of nine in the electrolyte with a gold concentration of 2.5 g dm(-3). The stability of the complex was studied by visual monitoring and electrochemical characterization of electrolytes over a period of 1 year. Electrochemical characterization of the mercaptotriazole gold complex was performed using open circuit potential measurement, cyclic voltammetry, recording the polarization curves, pH, and conductivity of the electrolyte. Electrochemical characteristics and visual appearance of the mercaptotriazole gold complex at a pH similar to 9 were not significantly changed for one year, with no changes in its visual appearance. The results of this study are important for industrial applications in order to replace cyanide electrolytes with a stable organic complex.

AB  - A detailed investigation of significance of the infrared (IR) spectroscopic branching factor (CH2/CH3; the ratio of methylene and methyl group peak heights at 2917-2921 and 2951-2954 cm(-1), respectively in the IR spectra) for characterization of alkane structure, geochemical properties and viscosity of 76 oil samples was performed. These oils, originating from 13 Serbian oil fields in SE Pannonian Basin, differ according to source and depositional environment of organic matter (OM), as well as by thermal maturity and biodegradation stage. Methylene and methyl asymmetric stretching peak absorbances were used for the branching factor calculation. CH2 peak positions exhibited 3-4 cm(-1) red shift with increasing the CH2/CH3 ratio, due to a greater contribution of trans vs. gauche rotamers in aliphatic chains. Comparing IR spectra of the oils and model n-alkanes, it was established that the average (CH2)(n) methylene chain length per CH3 group varied from n = 3.5 to 6.5. The CH2/CH3 ratio showed significant concordance with geochemical parameters, enabling clear distinction of the oils according to source and depositional environment of OM. At the same time, dependence of the CH2/CH3 ratio on oil maturity in the range from immature to mature was not observed, allowing for an accurate determination of oil genetic types irrespective of maturity. The CH2/CH3 ratio showed good accordance with oil biodegradation scale and oil viscosity.

AB  - Two samples collected from the phosphogypsum deposits of the chemical products industry Elixir Prahovo (Serbia) were subjected to a recrystallization experiment performed over several repeated cycles. In these tests, phosphogypsum was separated into recrystallized (purified) gypsum, insoluble residue and supernatant. Both raw phosphogypsum and recrystallized gypsum were examined using inductively coupled plasma optical emission spectrometry, X-ray diffraction and scanning electron microscopy with energy-dispersive spectrometry. The activity concentrations of (238)u, (235)u, Ra-226, Pb-210,Th- 232 and 40 K were investigated using gamma-ray spectrometry. Based on the activity concentration results, a number of radiometric parameters were calculated for the original and recrystallized phosphogypsum (i.e. radium equivalent activity, y indices for construction materials, a index and external and internal hazard indices). Raw phosphogypsum samples showed greater mean activity concentration levels of U-238 and Ra-226 than the international recommended limits, while the recrystallized gypsum demonstrated notably lower activity concentrations for these two isotopes. The activity concentration of Ra-226 in recrystallized gypsum is similar to 6 times lower than in raw phosphogypsum. Therefore, recrystallized gypsum does not present a radiation hazard when used as a building material, while raw phosphogypsum meets the requirements only for road construction materials.

'the negative effect of higher temperatures on the solubility of calcium sulfate (13.08 mmol/dm(3) at 95 degrees C vs. 15.43 mmol/dm(3) at 40 degrees C) was utilized. In several repeated cycles, calcium sulfate component was progressively dissolved in water at room temperature and then precipitated at 100 degrees C, using the same liquid phase throughout the experiment. Therefore, phosphogypsum was separated into recrystallized (purified) gypsum, insoluble residue and supernatant, and the mass balance for the experiment was calculated. Elemental, XRD and SEM-EDS analyses were performed on raw phosphogypsum, purified gypsum and insoluble residue. The whiteness of raw phosphogypsum and purified gypsum were determined and compared. The main objective of the study was to investigate the nature of insoluble impurities, in order to define and optimize the methods for their removal during a potential industrial processing of phosphogypsum.

like ore bodies have relatively high content of valuable metals. The average content varies in wide ranges: Pb

(~100–150 ppm). Generally, a complex mineral association has been determined. Iron sulfides, arsenopyrite,
chalcopyrite, sphalerite, galena and sulfosalts are abundant minerals in the ore. Carrier minerals of Bi and Ag
are Bi-sulfosalts, such as galenobismutite, cosalite, Ag-bearing aschamalmite, vikingite, schirmerite and gus-
tavite.  Copper,  Ag  and  Pb-Sb  sulfosalts  have  been  found  only  locally.  Complex  Ni-minerals  (sulfides,

ralizations have been found in the Nova Jama, Gušavi Potok and Azna ore zones. The presence of Bi-sulfo-

AB  - A series of novel C33-C35 hexacyclic benzohopanes have been identified in coals and crude oils
of different ages from all over the world [1]. They differ from regular benzohopanes by the presence
of methyl group in position C-31. These compounds are more abundant in coals and terrestrial oils.
The investigation also showed that mature samples have distributions of benzohopanes distinct from
immature ones, which are characterised by a greater number of benzohopane isomers. Although exact
structures of the additional isomers were not determined, it seems they were formed by an
isomerisation of alkyl groups attached to the aromatic ring.
Two novel monoaromatic hydrocarbons (MW = 270; basic fragment ions m/z 255 and 146)
were identified in coals, mudstones and crude oils. Their structures were determined as cis- and transicetexa-
8,11,13-trienes (or dehydroicetexanes) using NMR spectroscopy. Dehydroicetexanes are
potential biomarkers of Cupressaceae (cypress conifers).
Benzo[b]naphtho[d]furans (BNFs) have been identified in oils, condensates, source-rocks,
coals and coaly shales, being more abundant in the latter. We detected BNFs (m/z 218) in relatively
high amounts in the aromatic fractions of pyrolysates of brown coals which attained the maturity
corresponding to vitrinite reflectance of 1.80 %Rr [2]. This result suggests that BNFs can be attractive
for investigations of mature fluids that originate from gas/condensate prone sources, rich in type III
kerogen, which are usually depleted in biomarkers. Recently, it was observed that [2,1]/[1,2]BNF
ratio can be used to describe lithofacies [3]. This ratio is much lower in sediments from fluvial-deltaic
systems than in clay-depleted sediments from marine environments.
1-Chloro-n-alkanes (m/z 91) have been identified in saltmarsh vegetation, recent sediments
from estuarine setting and freshwater lake sediments [4]. Despite their absence in the investigated
crude oils, we identified a series of 1-chloro-n-alkanes in pyrolysates of the corresponding
asphaltenes, obtained at 250 oC. This result indicates very good preservation of biomarkers occluded
inside asphaltenes and announces a possible application of 1-chloro-n-alkanes in correlation studies.

AB  - The Turija oil field, being an important oil field in Serbia, is located in the Banat Depression of
the southeastern part of the Pannonian Basin. Oil samples from the Turija oil field were investigated
in order to estimate origin, depositional environment, thermal maturity and age of the corresponding
source rocks. For that purpose, a comprehensive analysis of biomarkers and aromatic compounds was
performed.
n-Alkanes are predominant compounds in the total ion chromatograms of saturated fractions of
all samples, showing that Turija oils are not biodegraded. The distributions of n-alkanes, which are
characterised by equivalent abundances of long- and short-chain homologues and maximums at C17,
C21 and C27, suggest a mixed aquatic-terrestrial origin. The uniform distributions of regular C27-C29
5α(H)14α(H)17α(H) 20(R) steranes support the previous assumption. The presence of oleanane in all
samples is indicative for a contribution of angiosperm plants to the precursor organic matter (OM).
Furthermore, the presence of this biomarker implies the Upper Cretaceous or younger age of the
corresponding source rocks. Isoreniratane and its derivatives have been identified in all samples.
Although isorenieratane can originate from β-carotene, which is widespread in algae, bacteria and
terrestrial plants, the presence of other catagenetic products of isorenieratene (mass fragmentogram
m/z 133 of the aromatic fraction) unambiguously confirms a contribution of green sulphur bacteria
Chlorobiaceae to the precursor organic material [1].
The pristane to phytane (Pr/Ph) ratio ranges from 0.64 to 1.17, indicating reducing to dysoxic
conditions during the deposition of precursor OM. The presence of the above mentioned
isorenieratane derivatives implies the photic zone of anoxia. The stratification of water column is also
supported by the presence of gammacerane and values of gammacerane index, GI = gammacerane x

associated with the values of MTTC ratio (MTTC = 5,7,8-trimethyl-MTTC/ΣMTTCs) in 0.44 to 0.65

abstract = "The Turija oil field, being an important oil field in Serbia, is located in the Banat Depression of
the southeastern part of the Pannonian Basin. Oil samples from the Turija oil field were investigated
in order to estimate origin, depositional environment, thermal maturity and age of the corresponding
source rocks. For that purpose, a comprehensive analysis of biomarkers and aromatic compounds was
performed.
n-Alkanes are predominant compounds in the total ion chromatograms of saturated fractions of
all samples, showing that Turija oils are not biodegraded. The distributions of n-alkanes, which are
characterised by equivalent abundances of long- and short-chain homologues and maximums at C17,
C21 and C27, suggest a mixed aquatic-terrestrial origin. The uniform distributions of regular C27-C29
5α(H)14α(H)17α(H) 20(R) steranes support the previous assumption. The presence of oleanane in all
samples is indicative for a contribution of angiosperm plants to the precursor organic matter (OM).
Furthermore, the presence of this biomarker implies the Upper Cretaceous or younger age of the
corresponding source rocks. Isoreniratane and its derivatives have been identified in all samples.
Although isorenieratane can originate from β-carotene, which is widespread in algae, bacteria and
terrestrial plants, the presence of other catagenetic products of isorenieratene (mass fragmentogram
m/z 133 of the aromatic fraction) unambiguously confirms a contribution of green sulphur bacteria
Chlorobiaceae to the precursor organic material [1].
The pristane to phytane (Pr/Ph) ratio ranges from 0.64 to 1.17, indicating reducing to dysoxic
conditions during the deposition of precursor OM. The presence of the above mentioned
isorenieratane derivatives implies the photic zone of anoxia. The stratification of water column is also

AB  - Савремена проучавања тектонских односа у Панонском басену се заснивају на наглашеној
унутрашњој деформисаности главних тектонских јединица којe изграђују основу басена, наспрам

пределима у Моравском рову, као што су Црни Врх, Мојсињске и Послонске планине, чине се‐
верни део Српско‐македонског масива. Српско‐македонски масив се одликује средње до високо
метаморфисаним фацијама представљеним гнајсевима, дволискунским шкриљцима и амфиболи‐
тима (Dimitrijević, 1997). Ова тектонска јединица се може корелисати са јединицом Бихарија,
заједно чинећи структурно највише делове Дакијске јединице која се одликује Европским тек‐
тонским афинитетом (Matenco and Radivojević, 2012). Новија термохронолошка истраживања на
југоистоку Србије и у околини указују да се врхунац метаморфизма у Српско‐македонском масиву
одиграо током варисцинског циклуса док је током целог палеозоика долазило до магматске
активности (Antić et al., 2016a). Јужно од истраживаног простора, везана кинематска и термохро‐
нолошка истраживања на планини Јастребац, указују да је касно кредни екстензиони детачмент
раздвојио високометаморфисане стене Српско‐македонског масива у подини од слабије метамор‐
фисаних стена Супрагетикума у повлати (Erak et al., 2016). Ова врста и старост деформација су у
новије време описане у суседним областима, по ободу Динарида, које се налазе у сличним
тектонским условима. Ови догађаји су везани за екстензију које је захватила fore‐arc подлогу
током субдукције Неотетиса крајем креде (Antić et al., 2016b; Toljić et al., 2018). Теренским
осматрањима се уочавају упадљиве морфолошке, структурне и литостратиграфске разлике између
метаморфита Јухорa и околних миоценских до квартарних наслага. Ово указује да су каснији де‐
формациони догађаји који су захватили северне делове Српско‐македонског масива везани за
формирање и развој југоисточног обода Панонског басена. Остаје доста непознатих чињеница о
прецизнијем временском оквиру и износима тектонског издизања Јухора. У циљу одређивања
износа ексхумације у северним деловима Српско‐македонског масива, спроведена су кинематска

фита на Јухору што се може довести у везу са екстензионом реактивацијом контакта Српско‐ма‐
кедонског масива и Супрагетикума током миоцена. Реактивација се догодила дуж екстензионог
детачмента у чијој подини се налазе метаморфити Јухора док је у повлати дошло до таложења
доње до средње миоценских наслага у Моравској депресији (Моравски детачмент према Sant et

AB  - Studies on recent tectonic setting of the Pannonian Basin argue for the internal deformation of
principal tectonic units constituting the basement of the basin, rather than motion along the boundaries
of large‐scale fully rigid blocks (Bada et al., 2007). The Juhor Mts in central Serbia represent an inselberg
of Proterozoic to Paleozoic age amphibolite‐facies metamorphics surrounded by Miocene to Quaternary
sediments of the southernmost Pannonian Basin. The Juhor Mts, together with other uplifted areas
along the Morava river corridor, such as Crni Vrh, Mojsinjske Mts, Poslonske Mts, comprise part of
northern Serbomacedonian Massif. The Serbomacedonian Massif is characterized by a medium to
high‐degree metamorphic sequence comprised of gneisses, two‐mica schists and amphibolites (e.g. Dimitrijević,
1997). This unit can be correlated with the Biharia nappe, together defining structurally
highest parts of the European‐derived Dacia mega‐unit (Matenco and Radivojević, 2012). Recent
thermochronological studies in the SE Serbia and adjacent countries have inferred that the peak
metamorphic event in the Serbomacedonian unit is Variscan and that its magmatism had a long
Paleozoic evolution (Antić et al., 2016a). South of our study area, a coupled kinematic and thermochronological
study conducted in the Jastrebac Mts has inferred a Late Cretaceous extensional detachment
creating the separation between the high‐grade metamorphics of the Serbomacedonian unit
in the footwall and the weakly metamorphic Supragetic nappe in the hanging‐wall (Erak et al., 2016).
This type and age of deformation was recently described in other neighbouring areas situated in similar
tectonic positions along the Dinaridic strike and are related to the extension recorded in the fore‐arc
basement during the Late Cretaceous subduction of the Neotethys Ocean (see also Antić et al., 2016b;
Toljić et al., 2018). Field observations show striking morphological, structural, and litho‐stratigraphic
contrast between the Juhor metamorphics and the adjacent Miocene to Quaternary deposits. Hence,
the observed omission could infer that the later stages of deformation in the northern Serbomacedonian
Massif were directly related to formation and evolution of the southeastern Pannonian Basin.
However, not much is known about the actual timing and amounts of the mountains tectonic uplift. In
order to quantify the recent stages of exhumation in the northern Serbomacedonian Massif we
conducted a coupled kinematic and thermochronological study. Preliminary results of our AFT and AHe
thermochronological study yield Miocene age cooling in the Juhor metamophites, thus inferring Miocene
extensional reactivation of the Serbomacedonian and Supragetic nappes contact. This reactivation
occurred along extensional detachment, whereby Juhor metamorphites represent exhumed footwall
while the hanging wall accommodated Lower to Middle Miocene deposition of the Morava depression
(the Morava detachment, see Sant et al., 2016). Subsequent Pliocene to Quaternary inversion of the
Pannonian Basin resulted in further differentiation between uplifted and subsided tectonic blocks along
southern margin of the basin.

AB  - The mineral aschamalmite, of heyrovskyite-like composition, but different in structure, from the Rudnik Pb–Zn/Cu,Ag,Bi,W polymetallic deposit in the central part of Serbia has been investigated. This polymetallic deposit includes over 90 hydrothermal and skarn-replacement orebody types, primarily hosted by Cretaceous sediments and occassionally by Oligocene dykes and sills of dacitic composition, and contact-metamorphic-metasomatic rocks. These rocks are host to an assemblage of pyrrhotite, colloform pyrite, chalcopyrite, galena, arsenopyrite, native bismuth and scheelite as well as minor pyrite, sphalerite, bismuthinite, argentopentlandite, and native silver. The chemical composition of the ore is very complex, where weight contents of valuable metals range as follows (%): Zn 0.49–4.49; Pb 0.90–5.66; Cu 0.08–2.18; WO3 0.05–1.18; Ag 0.005–0.030; Bi 0.005–0.081; and Cd 0.002–0.016. In reflected light, aschamalmite is optically anisotropic, with moderately high bireflectance ranging from slightly greenish to slightly gray. Electron-microprobe analysis gave an average crystallochemical formulae of (Pb5.82Ag0.20)Σ6.02Bi2.03(S8.93Te0.02Se0.01)Σ8.96. The strongest diffraction maximums of the X-ray powder pattern [d(in Å)(I)] are 3.419(100), 3.382(92), and 3.334(66). Monoclinic unit cell parameters are a=13.727(7); b=4.122(3); c=31.32(2) Å; β=90.72(5) o; and V=1771.8(1) Å3. Mineral assemblages and genesis of the Rudnik polymetallic deposit are discussed in detail and the sulfobismuthite mineralization has been compared with similar well-known global deposits.

AB  - Čumavići is a medium– to low–temperature hydrothermal Sb–Zn–Pb–Ag polymetallic vein–type ore deposit in the Srebrenica orefield, part of the Podrinje Metallogenic District, Eastern Bosnia and Herzegovina. The ore deposit occurs in the form of simple and complex veins along faults and fractures, as well as stockworks and disseminations hosted within Neogene volcanic rocks (pyroclastics and andesite lavas of calc–alkaline affinity). The deposit comprises sulfides (sphalerite, galena, stibnite, pyrite, marcasite, chalcopyrite, arsenopyrite, gudmundite, safflorite, löllingite, gersdorffite and acanthite), sulfosalts (berthierite, geocronite, boulangerite, semseyite, plagionite, jamesonite, bournonite, twinnite, andorite, fizéliyte, Ag–bearing tetrahedrite, stephanite, polybasite, pyrargyrite and argyrodite), native gold and silver, tungstates (hübnerite), oxides, and gangue quartz, chalcedony, Mn–siderite, anglesite, smithsonite, fluorite, gypsum and ludlamite. Three generations of sphalerite are recognized in the Čumavići deposit, evolving from Fe–rich to Fe–poor. The most common are yellowish to colorless Fe–poor varieties. Electron Probe Microanalyses of sphalerite free of micro–inclusions of galena and Pb–Sb-sulfosalts revealed wide compositional variations in minor- and trace–element contents (e.g., Fe, Cd, Mn, Cu, Sn, As, and In). Of particular interest are the lead and antimony content of sphalerite, which vary from 0.10 to 3.08, and 0.02 to 1.62 wt.%, respectively. Lead– and Pb–Sb-rich zones are the most common in sphalerite, while individual Sb–bearing zones are rare. These zones have fan–like forms with circular to wave-like, micron–scale bands, filled with galena or Pb–Sb sulfosalts. In the Pb–Sb zones, the Sb/Pb atomic ratio ranges between 0.3 and 1.5, similar to ratios between geocronite and jamesonite, thus suggesting the presence of micro– to nano–scale inclusion of sulfosalts within the sphalerite. The mean composition of all sphalerite samples is (Zn0.78–0.99,Fe< 0.01–0.21,Cu0.00–0.02,Pb< 0.01–0.01,Cd< 0.01–0.01,Sb< 0.01–0.01,Mn< 0.01–0.01)∑ 0.97–1.03S0.97–1.08 (Sn and As atomic proportions are < 0.01 apfu). In all sphalerite samples, excellent negative correlations have been determined between Fe and Zn, and ∑(Fe + Sb) and Zn. The studied mineralization shares many mineralogical and geological characteristics in common to polymetallic Sn–Ag–Sb deposits in Bolivia and elsewhere.

AB  - (Ni-Sb)-bearing Cu-arsenides are rare minerals within the Mlakva and Kram mining sectors (Boranja ore field) one of the less-known Serbian Cu deposits. (Ni-Sb)-bearing Cu-arsenides were collected from the Mlakva skarn-replacement Cu(Ag,Bi)-FeS polymetallic deposit. The identified phases include β-domeykite, Ni-bearing koutekite and (Ni-Sb)-bearing α-domeykite. (Ni-Sb)-bearing Cu-arsenides are associated with nickeline, arsenical breithauptite, chalcocite, native Ag, native Pb and litharge. Pyrrhotite, pyrite, chalcopyrite, cubanite, bismuthinite, molybdenite, sphalerite, galena, Pb(Cu)-Bi sulfosalts and native Bi, as well as minor magnetite, scheelite and powellite are associated with the sulfide paragenesis. The electron microprobe analyses of the (Ni-Sb)-bearing Cu-arsenides yielded the following average formulae: (Cu2.73,Ni0.17,Fe0.03,Ag0.01)∑ 2.94(As0.98,Sb0.05,S0.02)∑ 1.06–β-domeykite (simplified formula (Cu2.7,Ni0.2)∑ 2.9As1.1); (Cu3.40,Ni1.40,Fe0.11)∑ 4.91(As1.94,Sb0.13,S0.02)∑ 2.08–Ni-bearing koutekite (simplified formula (Cu3.4Ni1.5)∑ 4.9As2.1); and Cu1.97(Ni0.98,Fe0.03)∑ 1.01(As0.81,Sb0.22)∑ 1.03–(Ni–Sb)-bearing α-domeykite (simplified formula Cu2NiAs).

AB  - The artificial maturation changes of the humic coal organic matter (OM) from late diagenesis to the semianthracite stage of coalification were investigated using the closed-system pyrolysis. Two extracted coal samples, a subbituminous coal 26C (with a random vitrinite reflectance Rr = 0.42%) and a high volatile bituminous coal 30C (Rr = 0.56%), were pyrolysed during 4 hat two different temperatures, 250 degrees C and 400 degrees C. The applied petrographic and organic geochemical analyses showed that the humic coal OM is sensitive to the artificial thermal stress. A good correlation between the changes in petrographic characteristics and the derived liquid products was observed. The contents of all vitrinite macerals, as well as total vitrinite, increased during the thermal maturation. The abundance of liptinite macerals decreased during the maturation and they practically disappeared after 4 h of the pyrolysis at 400 degrees C. The total inertinite contents increased after the pyrolysis at 250 degrees C, yet to be decreased after the pyrolysis at 400 degrees C. The content of organic carbon increased from coals to the solid residues at 400 degrees C, whereas the contents of total hydrogen and sulphur decreased. The yields of gases, liquid products and solid residues at respective temperatures were very similar for both coals, regardless of the rank. As expected, the pyrolysis at 400 degrees C gave higher gas and liquid yields than at 250 degrees C. Regarding the liquid pyrolysates, more pronounced changes were observed in the distribution of aromatic compounds than in saturated biomarkers. The distributions of the aromatics indicate that apart from cracking and isomerisation (the formation of thermodynamically more stable isomers), the reactions of dehydrocyclization, condensation (the formation of more stable conjugated systems) and aromatization, as well as reactions involving H2S, elemental sulphur and reactive phenyl radicals released during the pyrolysis, also play an important role. It was shown that bentonitic clay plays a more important role in the subsequent aromatization of the OM than the initial maturity of the coal OM. n-Alkane parameters were useful at lower maturities (up to similar to 0.75% Rr), whereas sterane, naphthalene and phenanthrene maturity ratios are applicable at higher maturities (>0.75% Rr). Hopane parameters showed variable sensitivities over the investigated maturity range (0.5-1.8% Rr). The most sensitive maturity parameters in the wide range of the humic OM maturity (0.5-1.8% Rr) are vitrinite reflectance, phenylnaphthalene ratio, methylchrysene index 2 and a parameter proposed in this study, based on the distribution of methylfluorenes (MF): (2- + 3-MF) / (1- + 4-MF). Generally, maturity parameters based solely on the isomerisation reactions of alkylaromatics, which do not include alkylation/dealkylation processes, are more appropriate for the humic OM, particularly at higher maturities.

The total inertinite contents increased after the pyrolysis at 250 degrees C, yet to be decreased after the pyrolysis at 400 degrees C. The content of organic carbon increased from coals to the solid residues at 400 degrees C, whereas the contents of total hydrogen and sulphur decreased. The yields of gases, liquid products and solid residues at respective temperatures were very similar for both coals, regardless of the rank. As expected, the pyrolysis at 400 degrees C gave higher gas and liquid yields than at 250 degrees C. Regarding the liquid pyrolysates, more pronounced changes were observed in the distribution of aromatic compounds than in saturated biomarkers. The distributions of the aromatics indicate that apart from cracking and isomerisation (the formation of thermodynamically more stable isomers), the reactions of dehydrocyclization, condensation (the formation of more stable conjugated systems) and aromatization, as well as reactions involving H2S, elemental sulphur and reactive phenyl radicals released during the pyrolysis, also play an important role. It was shown that bentonitic clay plays a more important role in the subsequent aromatization of the OM than the initial maturity of the coal OM. n-Alkane parameters were useful at lower maturities (up to similar to 0.75% Rr), whereas sterane, naphthalene and phenanthrene maturity ratios are applicable at higher maturities (>0.75% Rr). Hopane parameters showed variable sensitivities over the investigated maturity range (0.5-1.8% Rr). The most sensitive maturity parameters in the wide range of the humic OM maturity (0.5-1.8% Rr) are vitrinite reflectance, phenylnaphthalene ratio, methylchrysene index 2 and a parameter proposed in this study, based on the distribution of methylfluorenes (MF): (2- + 3-MF) / (1- + 4-MF). Generally, maturity parameters based solely on the isomerisation reactions of alkylaromatics, which do not include alkylation/dealkylation processes, are more appropriate for the humic OM, particularly at higher maturities.",
