摘　　要：The relations between ultrabasic rocks and gold deposits in time, space and genesisare discussed in this paper. The research results show that the ore-forming materials of the golddeposits is characteristic of crust-mantle mixing. The formation of the gold deposits is relatedwith the activity of juvenile fluids along with the intrusion of ultrabasic dikes. The ascendingjuvenile fluids not only offered Part of the gold, water and mineralizers for gold ndneralhation,but also promoted the remobilization, defortion and enrichment of gold in crustal sediments.The relations between ultrabasic rocks and gold deposits in time, space and genesisare discussed in this paper.
