Gold-Platinoid Mineralization in Ferruginous Quartzites and Shales of Kursk Magnetic Anomaly — a Single Ore-Forming System

Language: Russian

Mineralogical journal 2015, 37 (3): 78-97

Abstract: New data on the Paleoproterozoic noble-metal-bearing structure-material complexes and their parageneses in two ore district of the Kursk Magnetic Anomaly, spatially separated and different in composition of enclosing ferruginous quartzites and black shales, are presented. A multi-stage character of the formation of noble-metal types of ores is established; the single type composition of the mineral phases in the ferruginous quartzites, shales and metasomatites is determined, that evidences for its belonging to a single long developing ore-forming system. The generalized model of the formation of the noble-metal- bearing ore-forming system in case of genetically variable sources of material is given.

Keywords: noble metals, mineralogy, iron ores, carbonaceous shales, types of mineralization, ore-forming systems, model of formation.
