Localization conditions and the gold content of the sCarns Of zygyrkol ore zone (Kabardino-Balkarskaya republic)

Abstract

Are described the geological conditions for localization of the gold-bearing Zygyrkol ore zone scarns, revealed with the participation of the authors in recent years on the northern flank of Tyrnyauz ore unit. Is established the prolonged (from the late Paleozoic period) development of deformations within the limits of Gitche-Tyrnyauz ore field, and that to shaping of productive to gold Zygyrkol ore zone gave vertical tension and the reverse fault-shift deformations of Alpine stage. Four sections of the development of gold-bearing scarns are isolated. Nature and degree of their gold content are opened. They are determined by the level of the Zygyrkol zone denudation shear, which rises up in the North Western direction hearth by smaller angle than is raised relief, which leads to the withdrawal under the relief of optimum ore-bearing level. The lower section, where the gold-bearing scarns leave to the earth’s surface, possesses the optimum level of shear. The crossing section, where the scarns productive to gold are located on 100-200 m lower than earth’s surface, possesses the minimum level of shear.
