Formation Features and Prediction Criteria for Gold-Sulphide deposits (East Kazakhstan)

Abstract

The region under consideration is part of the Central Asian mobile belt system, organized by a large geo structure of the Greater Altai (GA), which integrates geological structures of the Rudny Altai, Kalba, Zharma-Saur and adjacent districts of Russia and China. The regional goldore sites vary by ore formation types, age, geological formation conditions and mineralization scale. The largest among them are the Ridder-Sokolny gold-polymetallic deposit in the Rudny Altai and the Bakyrchik deposit of the gold-sulphide-carbonaceous type in West Kalba, comparable in many ways with the world sites of Sukhoi Log and MurynTau in the black shale strata. In recent years, much attention was paid to prediction and assessment of the unconventional (apocarbonate) goldsulphide type of mineralization, associated with the island volcanic-carbonate-terrigenous formation С1v2-3 (the Suzdal deposit and others). The present paper considers new results acquired from the studies of the gold-ore sites of the Suzdal type.
