AB  - During the long geological past, the rocks of the Adriatic block were formed, which includes the rim of Cer and the Adriatic base. The rim of Cer is characterized by igneous rocks - granite, granodiorite and Paleozoic shale, while the Jadar basin is built of lake sediments that include mainly clay, sand, gravel, sandstone, sandy limestone. Some of these constituents are classified as kaolin raw materials. Kaolin raw materials can be formed during hydrothermal decomposition, kaolinization, which implies physical and chemical changes of various rocks of igneous origin, which contain feldspar and mica, such as granite. As the study of silicate raw materials used in the construction and ceramic industry is a very important and continuous problem, within this paper a more detailed chemical-mineralogical-physical characterization of four kaolinized granite composites (KI, KII, KIII and KIV) from the Beli Majdan deposit-Jadranska Lešnica. Kaolinized granites are formed by subvolcanic decay of granite. In technological terms, these are weakly bound rocks, which are comminuted into smaller aggregates by the grinding process. The techniques used in this study to examine kaolinized granite composite samples included chemical analysis, X-ray diffraction (X-ray), differential thermal analysis (DTA), and ignition tests at three selected temperatures (1000, 1100, and 1250°C). Based on X-ray analysis, it can be concluded that the mineral composition of the kaolinized granite composite "Beli Majdan"-Jadranska Lešnica includes quartz, feldspar, mica, calcite/dolomite and clay minerals. The most common minerals are quartz and feldspar (aluminosilicate containing cations of alkali and alkaline earth metals). Minerals from the mica group as well as carbonates (Ca and Mg) occur in smaller quantities. The results of chemical analysis showed that the Al2O3 content in the tested composites ranged from 19.02 to 21.04%, and the Fe2O3 content from 1.48 to 1.65%. Additionally, the K2O content in the tested composites ranges from 5.32 to 6.45%, which indicates the presence of k-feldspar and muscovite, and the Na2O content from 1.78 to 2.64%. The results of DTA analysis in all four composites indicated the presence of quartz and clay minerals. The ignition color is from brick red to dark brown red. Based on the obtained experimental results, it can be concluded that kaolinized granite "Beli Majdan"-Jadranska Lešnica is a quality raw material for composing ceramic masses in the production of ceramic tiles. It acts as a solvent and can partially or completely replace feldspar in ceramic masses.
