摘要
Abstract
Tangjiagou gold deposit is a medium-sized gold deposit in southwest of Mouping-Rushan gold belt in Jiaodong area.Its main overlying layers are metamorphic rocks in Proterozoic Jingshan group,Cenozoic and Quar-ternary.Structures are mainly composed of Paleo -proterozoic fold structures and Mesozoic faults.Among them, gold-bearing mineralization belts are controlled by fractures with the trend of NNE.Main ore bodies are distribu-ted in the trend of NNE,and ore types are mainly pyritized quartz vein and pyritized cataclasite.The thickness of main ore bodies has a positive relation with grade,and mineralization has the characteristics of multi-stage activi-ties.It is found that the intersection areas of ore-controlling structures and other structures and the corners of ore-controlling structures are favourable ore-contained places,while mineralized alteration superposition areas have great deep prospecting potentiality.It is predicated that intersection areas of gold mineralization fractural structures with the trend of NNE,sulfide enrichment belts and hidden faults,as well as iron and gold mineralization belts, and the contact areas of Jingshan group are metallogenetic favorable zones.关键词
