Abstract :

The productive mineralization of the Sheikhdzheili-Zengiboba area is associated with metamorphogenic transformations of the rocks of the Urusai, Karauzyak, Kuyanchik, Sheikhdzheili suites, metamorphosed under conditions of green schist facies. The mineralized zones of the site are confined to narrow faults in the tectonic zones of the northeast and northwest directions. The main form of manifestation of gold-bearing mineralization is small steeply dipping veins, lenses, nests, non-extended systems of conformal and secant quartz veinlets containing dissemination of pyrite, arsenopyrite, chalcopyrite and pyrrhotite, which are represented by gold-arsenopyrite-pyrite, gold-arsenopyrite-chalcopyrite-pyrite natural type of ores.
