Specific features of gold ore formation in the southeastern Baikal-Patom metallogenic province (Dzhalagun ore field)

Abstract

In the course of geological prospecting fulfilled with participation of the FGBI TsNIGRI within the Chayangro ore cluster of the Dodykhta-Uryakh ore region in the southeastern Baikal-Patom metallogenic province, the Dzhalagun lode gold prospect within the ore field of the same name was studied and its economic significance has been proved. It has been substantiated that the Dzhalagun gold prospect is closely similar to the typical gold ore deposits of the Bodaibo ore region in sense of the ore formation phasing, the character of the hydrothermal metasomatic processes, and the structure of the mineralized vein-veinlet zones. At the same time, a series of specific geological features of the Dzhalagun ore field and the prospect have been determined as to the structure and composition of the ore-hosting rocks, the intrusive magmatism, the hydrothermal metasomatic processes, and the mineral composition of the vein-veinlet mineralization.
