About intrusive rocks of the Sarbaisky deposit
Abstract
The article presents new data on intrusive rocks of the Sarbaiskoye deposit, obtained as a result of the works of the geological party of the Leningrad Mining Institute.Sarbaiskoye magnetite ore deposit is one of the largest among the deposits of the Kustanai iron ore province. I. A. Kochergin and G. A. Sokolov consider this deposit to be a contact-metasomatic deposit, confined to the contact of a multiphase intrusion of diorite-porphyrites with volcanogenic-sedimentary rocks of the Lower Carboniferous. Among the intrusive rocks I. A. Kochergin distinguishes: 1) pre-metallic: [a) diorite-porphyrites of the main intrusion; b) vein diorite-porphyrites; c) metadiorite-porphyrites]; 2) post-ore: [a) vein quartz diorite-porphyrites; b) syenite-porphyrites: [according to G. A. Sokolov, microgranite porphyries].
