摘　　要：东乡枫林铜矿位于江西省抚州市东乡区北东6km处,是一个以铜为主的中型铜硫铁钨矿床。业界对东乡铜矿成因存有海底喷流沉积、海相火山沉积和岩浆热液型以及多因复成矿床之争议,本文充分利用前人的研究成果,结合矿石特征、石炭系地层成矿元素丰度、花岗斑岩体的赋矿特征,初步认为东乡铜矿为海相火山沉积+岩浆热液叠加改造的“多位一体”铜矿床。Fenglin copper mine is located 6km northeast of Dongxiang District,Fuzhou City,Jiangxi Province.There are many disputes on the origin of Dongxiang Copper Deposit,such as submarine exhalation deposit,marine volcanic deposit,magmatic hydrothermal type and polygenetic compound deposit.This paper makes full use of the previous research results,combines the ore characteristics,the abundance of ore-forming elements in Carboniferous strata and the ore-forming characteristics of granite porphyry,and preliminarily considers that Dongxiang Copper Deposit is a"multi-component"of marine volcanic deposit+magmatic hydrothermal superimposition and transformation Copper deposits.
