Sažetak
Crnac is a Pb-Zn-Ag underground mine, under operation, comprises two types of mineralization: epithermal vein type and mineralized listwaenites. Sericite concentrate from vein type mineralisation yield an Ar/Ar age at 27.7± 0.6 Ma, interpreted as the age of mineralisation, while significantly younger age of ca. 21.8± 0.9 Ma, in first step is interpreted as the maximum age of a second, low-temperature overprint. Boiling evidences are found in all phases of mineralisation. Salinities in pre- and syn- mineralisation phases strongly decreased in comparison to the vein type mineralization placed below. This is explained by the extensive boiling and mixing with meteoric water, which increased influence in uppermost part of the deposit as well as the water-rock reactions e.g. listwaenitization, of the overlying plastic cap-rock serpentinite.
