摘要
常宁铜鼓塘富铜(银铀)矿床,以Ⅵ号主矿体为代表,具有以辉铜矿为主的矿物组合。本文根据Cu、(Ag)的地球化学行为,阐述了不同条件下,Cu、Fe与S、O的亲疏倾向,从而形成各矿体独具特色的矿物共生组合特征。进而讨论了矿床的特定成矿环境和典型岩溶成因。最后,笔者综合分析了多种有利成矿因素,指出金鸡岭背斜及其以北地段,是普查同类型富铜矿床的远景地区。
Tonggutang rich copper(silver and uranium)deposit in Changning countv, which can be represented by the main orebody Ⅵ,is of mineral assemblage dominated by chalcocite. Based on the geochemical behaviour of Cu、(Ag),this paper expounds the geochemical coherence and estranging relationship between Cu、Fe and S、O in different conditions, which causes to from diversified paragenetic association of minerals, unique to each orebody. Moreover,the specific oreforming environment and the typical karst origin of the deposit are discussed.Fina11y,the favourable metallogenic facors are comprehensivl analysed and it is pointed out that the Jinjiling anticline and its northword area is the target to be explored for rich copper deposit of the same kind.
