摘要
Abstract
The Taopingshan mining area is located in Liancheng county,Fujian province.It is a lead-zinc polymetallic deposit.On the basis of fully collecting and absorbing the geological data of the mining area,systematically studied and analysed the geological,geochemistry and scientific data of the Taopingshan mining area,it is considered that the evolution of Late Paleozoic and late Mesozoic tectono-magmatic rocks and the spatial-temporal distribution of ore-forming factors are the important basic geological problems that restrict the prospecting in Taopingshan mining area.The results of EPMA analysis of pyrite in the mining area show that the ore-forming hydrothermal solution mainly comes from volcanic magmatic hydrothermal solution,and the characteristics of sulfur,lead isotope tracer geochemistry are analyzed,it is inferred that sulfur in ore-forming process mainly comes from lower crust or upper mantle,and lead comes from orogenic belt and upper crust.Based on other typical deposits in the region,ore-forming factors are determined to guide the prospecting for these deposits under the nappe,coal measures and Mesozoic volcanic-sedimentary strata in southwestern Fujian.关键词
