| The units—Derong and Muli county lacated in the combining site of the southwest of Sichuan province and the Yunnan province,in the south of Yidun-Zhongdian islang arc belt,which is a concentrated zone of nonferrous and rare metals in the middle-north of the Sanjiang tectonic belt.There are complex regional geology background,fractures,magmatic rocks and the notable geophysical character, geochemistrical character and remote sensing character.We both discovered middle or big porphyry copper deposit in Yunnan province and the east of the research area in Muli county. Therefore,doing synthesis research,summarizing metallogenic regulation in research area are very significant.Through the research of the typical copper deposits'geological characters,such as Yangla,Pulang and Mofancun copper deposit, generalize the distribution regulation of the regional minerals,controlling factors and prospecting indicators.Contrasting Zhujiding,Hongzhuo and Rexiang copper sites founded three years ago with the typical deposits in geology background,mineralization characters, controlling factors and genetic model.we gain the conclution that the geology background of the Hongzhuo is similar to the Pulang-Xuejiping porphyry copper deposit.And Hongzhuo belong to the east extention of the Pulang-Xuejiping -Zhuoma porphyry copper belt.Zhujiding copper deposit and the north of the area's geology is different from the Pulang-Xuejiping -Mofancun's,so it is hard to prospect porphyry copper, but probably finding hydrotherm copper deposit.According to the 1:200000 original streaml sediment geochemistry grid data and the 1:50000 geochemistrical achievement,associated with the geological background,.And we consider the influence of the stream sediment's anomaly's high copper background in bedrock,which are the Emeishan basalt rocks (or it's equivalence srata) and granite batholites (stock). Associated with the minerogenic regularity and the factors,we screen 20 prospecting target areas... |
