Abstract:
The Chagojansky ore knot is located in the Amur region Russia. It is dated for an intruzivno-dome raising in a northeast part of Keruleno-Arguno-Mamynskogo of a composit file which is combined multiphase granitoid intrusion Paleosoic and the bottom chalk, with relic the roof executed carbonatic and terrigenno- sedimentary breeds early paleopaleosoic. As the basic mineralization control knot structures the Chagojansky anticline broken by a series of radial and concentric breaks on a number sink and lifted blocks acts. Are revealed ore mineralization gold beresitic, jasperoidic, quartzitic-propulitic, skarnic and quartz- polevoshpatovyh metasomatite formations. The most perspective is jasperoidic the formation (Karlin type). In knot territory the big group ore mineralization gold Karlin type and a number of sites of distribution carbonatic the formations which earlier have been not studied on this type gold ore is known.
