Abstract

The relations between ultrabasic rocks and gold deposits in time, space and genesis are discussed in this paper. The research results show that the ore-forming materials of the gold deposits is characteristic of crust-mantle mixing. The formation of the gold deposits is related with the activity of juvenile fluids along with the intrusion of ultrabasic dikes. The ascending juvenile fluids not only offered part of the gold, water and mineralizers for gold mineralization, but also promoted the remobilization, deposition and enrichment of gold in crustal sediments.
