Characteristics of endogenic mineralizations in the Th¹ch Kho¸n – Ba V× area
TrÇn Anh Ngoan
Endogenic mineralizations in the Th¹ch Kho¸n – Ba V× area are rather rich and various of two genetic types - Hydrothermal and pegmatite. The mineralizations are controled by igneous intrusions, fault structure and favourable petro-stratigraphic factors.
Iron, zinc, gold and pyrite mineralizations in Th¹ch Kho¸n are related to igneous intrusion of the §iÖn Biªn Complex. Copper, gold, pyrite and asbestos mineralizations in Ba V× are related to volcanites of the Viªn Nam Formation and Ba V× ultramafic intrusion.
Mineralization of radioelements are related to the Th¹ch Kho¸n pegmatite field.
Non-metallic mineralizations have large commercial values.
