On tectonic control of sulfide mineralization at the Sokolovskoye deposit
Abstract
The Sokolovskoye contact-metasomatic deposit of magnetite ores lies among sedimentary-volcanogenic rocks of the Valerian Formation monoclinally dipping to the east at an angle of 40-60°. In the southern part of the deposit, within the pit, the host rocks and magnetite ores have meridional strike and are tilted to the west at an angle of 70-80°, which is associated with displacement along the South Sokolov thrust. This thrust, dipping to the northwest at an angle of 45-48°, limits the ore zone of the Sokolovskoye deposit from the south. According to N. I. Rudenko, the tectonic structure of the deposit and its open pit part is blocky. In the west, between limestones and ores, N. I. Rudenko distinguishes a pre-ore meridional disturbance, which is considered as the main solution-feeding disturbance. Parallel to the main one in the central part of the ore zone is the Central meridional disturbance, extending only within the open pit. ...
