Abstract

 Moshan gold deposit which was discovered in the northeastern of Queshan rock mass and controlled by the small-sized faults and fractures,belongs to fracuture zone alteration rock pattern gold deposit.According to the comprehensive analysis of ore characteristics,main metallic mineral characteristics and gold mineral characteristics,the mineral assemblage of ore and their formation order were determined and the formation of Moshan gold deposit was dividen into three mineralization stages.This paper holds the viewpoint that mineral assemblage of Jiaodong gold deposits are distinctly different from those of orogenic gold deposits and epithermal gold deposits,and they are a unique deposit type.The research shows that gold minerals of ore are native gold,and particle size of gold mainly varies between middle and coarse,visible gold is occasionally found,in addition,the mineral composition and particle size of gold mineral in eastern Shandong have obvious differences those in northwestern Shandon,fracture development in the host rock and the long term-influence of the early Cretaceous magmatism in mining area are the main cause of forming coarse gold.
