CONTROLLING STRUCTURES OF QIANHE GOLD DEPOSIT AND THEIR RELATIONSHIP WITH GDLD DEPOSITION

Qianhe gold deposit is mainly controlled by a EW fault developed on the north of the regional Lushi-Panhe-Machaoying fault. According to the relationship between faults, altered minerals and their paragenic characteristics, six structural activities and six corresponding stages of mineral development are recognized. The second to fifth stages are those of deposition characterized by silicification,epidotization,sericitization and chloritization,Ore bodies are mainly controlled by cataclast belt and joint-controlled bodies occurs largely on sides of controlling faults. The contents of elements Ag, Cu, Pb, Zn, Mo and Ni are all increased along the fault belt. And Ag, Cu, Pb and Zn higher in the east and Bi, Mo, Cr, Co and Ni higher in the west of the deposit. Ag, Cu, Pb, and Zn are rich in the upper part of ore bodies; Bi, Mo, Cr, Co, Ni are rich in the middle and lower part, Such a conclusion can be reached that the ore bodies seen in the east belong to the middle and upper part of a large body and those in the west to the middle and lower part. More attention should be paid to the lower part of the east part.
