NEW ABOUT TITANIUM CONTENT IN THE YAREGA ORE CLUSTER (SOUTHERN TIMAN)

The main results of geological, geophysical, geochemical and exploratory drilling works for PrecambrianShrenk-Faddeevskaya subduction fold belt zone, widespread in the Verhneleningradskaya area were carried out. Hence, analysis shows the new type gold-sulphide-quartz bearing zone, there were obtained productive gold-bearing intervals and calculated a forecast resources. Mineralization is characterized by multistage formation. It is localized in metasomatically altered Early-Upper Precambrian carbonaceous volcanogenic-carbonate-terrigenous stratas. The age of the mineralization is estimated 830–780 Ma. Recommendations are given for the production of further exploration.

Keywords: gold-sulphide-quartz formation, carbonaceous volcanogenic-carbonate-terrigenous stratas, Shrenk-Faddeevskaya accretion zone, Verhneleningradskaya area, geochemical halos, ore zone, ore field, ore occurrence, inferred ore.
