Geology of the Karalon Gold Ore Field in the Mid-Vitim Highlands

Аннотация

The paper present new data on the geology of the Karalon gold ore field in northern Buryatia, including its regional position and a brief description of the mineralization, gold–sulfide and gold–quartz–low-sulfide ore objects, host rocks, and complexes, which are components that make up juvenile Late Neoproterozoic Earth’s crust formed in the course of rifting. Paleozoic dike series are characterized, as well as the ore-controlling complex of beresite–listvenite metasomatic rocks. Regularities in the emplacement of gold objects and their control are generalized. Veins and veinlets of gold–quartz mineralization are hosted in gently and steeply dipping structures in the ore field, which formed prior to the intrusive Dogaldyn massif of subalkaline rocks 252 Ma ago.
