Reference information

Comments A dormant deposit in the Bor district. Adjacent to the Late Cretaceous to Early Tertiary Crni Vrh plutonic complex which was emplaced along a regional fracture zone on the western margin of the Timoc Magmatic Complex into Late Cretaceous andesites and clay-rich sediments. Alteration at the margins and in the central parts of the plutonic complex in a zone > 8 km long. Alteration includes propylitic, dominated by chlorite and epidote with silicification and pyritization. Valja Strz and Dumitru Potok deposits are relatively large but of sub-marginal grades; epithermal mineralization developed at the margins of these bodies (Porter GeoConsultancy, 2011). Porter GeoConsultancy (2011) reports that the plutons are generally potassic, and strontium 87Sr/86Sr ratios indicate a continental crust contaminated mantle source. Bor (Timoc) district.
