Dickite and kaolinite as alteration minerals within the Pb-Zn-Ag sulfide deposits on Northern Kosovo
The kaolin group of minerals is represented by kaolinite, dickite and nacrite. Identification of three polytypes with chemical formula Al4Si4O10(OH)8 can be achieved by combination of X-ray diffraction, Raman spectroscopy and scanning electron microscopy. Kaolinite occurs in hydrothermal ore veins, in hot springs deposits and as authigenic vermicular crystals in sediments. It is a common weathering product and is a major component of soils, residual clays, bauxites and certain sedimentary deposits. Dickite is generally related to the conditions of higher temperature and pressure and mainly occurs in hydrothermal environments. Nacrite is the rarest polytype among them and is mostly related to the hydrothermal systems. Kaolin minerals are recorded within two hydrothermal Pb-Zn-Ag sulfide deposits in the Northern Kosovo, related to the Late Palaeogene, post-collisional volcanism (Cvetković et al., 2004). Dickite occurs in the Trepča deposit and kaolinite is found in the Crnac deposit. This publication deals with genesis of dickite and kaolinite and presents their mineralogical characteristics. The geochemical conditions for the formation of dickite and kaolinite in Pb-Zn-Ag sulfide deposits in Kosovo are estimated on the basis of fluid inclusions data obtained from cogenetic quartz, spatially associated with the kaolin minerals.
