Abstract

The distribution of gold, silver, platinum, palladium, and rhodium in the Belozerka and Chara-Tokko greenstone structures is examined. The average Au content in both areas was found to be 10.6-22, which is 2.5-5 times higher than the normal background level (3.1-4.1 ppb). Three types of geochemical anomalies were identified: Au-Ag-As, Pt-Pd-Rh, and Au-Ag-PGE. These anomalies are confined to zones of faulting and hydrothermal metasomatism. Of particular interest are Au-Ag anomalies in fault zones in Archean metaterrigenous rocks and Au-Ag-PGE in magnetite quartzites containing sodic metasojnatites. Further work is required to assay these anomalies for the entire set of noble metals.
