Geological and geochemical features of the auriferous Butarny deposit
Tóm tắt
The Butarny deposit is characterized by the development of mineralization of gold-quartz and gold-rare metal mineral associations related to Late Cretaceous granitoid magmatism and metasomatism imposed during the Late Jurassic tectonomagmatic epoch. Ores on the Butarnoe site were formed during the vein quartz-sulphide stage and partially oxidized in a zone of hypergenesis. The gold found there is fine-grained and is also related to arsenopyrite and scorodite and, to a lower degree, to quartz and iron hydroxide
