Abstract

The new results of geologic-structural, petrographic and mineralogic-geochemical researches of Mykert-Sanzheevka ore field—the Uda-Vitim mineragenic zone South-West ending of West Transbaikalia are given. In the article the research results of noble-metal-polymetallic mineralization of Mykert-Sanzheevka ore field are presented. Its main ore-controlling structure, represented by losange, consisting of rhombohedral and tetrahedral blocks-duplexes mosaic clusters, which are separated by narrow tectonic sutures, is specified. It is clarified that polycomponent ores clusters are confined with these small-block sutures, made by subvolcanic dykes of shoshonitelatite volcanoplutonic association (233 - 188 million years), apodyke dynamometamorphites (breccias, cataclasite, mylonites) and also mechanometasomatites. Four stages of the dynamometamorphites formation characterized by different species compositions of ore minerals appeared as a result of mechanochemical reactions are determined. Small Mykert field of Sanzheevka mineral occurrence and Big Mykert form a single ore field A carbonyl model of mineral microaggregates formation with films containing noble metal nano-particles is proposed. Oreforming system features of Mykert-Sanzheevka field are considered.
