Abstract

The article describes characteristics of hydrothermalites and ore-metasomatic rocks of Gerfed gold deposit - their structure, genesis, distinctive features of gold content. It presents data on the distribution of gold and its forms in various gold-bearing formations. The Gerfed deposit is localized at the contact of Penchenginskaya and Kordinskaya series, which was the geochemical, lithological and structural constraint and determined the nature and location of mineralization. The Gerfed goldfield has hydrothermal metasomatic origin, formed at relatively great depths in a short period of time as a result of crystallization of single servings of medium-temperature fluid at the tectonic deformation of the environment. It refers to the low-sulphide gold silica formation of pyrite-arsenopyrite type and its structure characterized by a combination of metasomatic replacement processes of early and later execution of voids. Gold on the deposit is mostly free and in intergrowths forms, sulfide component is negligible. The field is highly uneven distribution of gold grade - from background values up to 142 or even 953.2 gram per ton.
