VOLCANOGENIC MASSIVE SULFIDE DEPOSITS ENRICHED IN GOLD
https://doi.org/10.33623/0579-9406-2018-3-3-11
Abstract
Volcanogenic massive sulfide deposits contain Cu, Zn, Pb, Sb, Bi, Te, Se, Ag, Co and variable amounts of Ag and Au. In some of them gold reserves exceed 100 t while gold grades reach several dozens ppm. Original data base was used to establish statistically meaningful criteria for identification of deposits with large gold reserves and/or anomalously enriched in gold. Some peculiar features of deposits with high Au grades were investigated including distribution in geological history and among the principal metallogenic provinces, association with volcanogenic formations and paleovolcanic structures, geochemical and mineralogical features and factors that caused enrichment in gold.
