【摘要】 以冬瓜山层状铜矿床为例,通过成矿地质背景和矿床地质特征研究,探讨层状铜矿床成因。研究发现冬瓜山层状铜矿床是在原始矿胚层沉积基础上,经燕山期岩浆热液叠加成矿作用所形成层状铜矿床,成矿作用经历了两个成矿阶段:早阶段是由泥盆至石炭纪喷流沉积形成的块状硫化矿床,晚阶段受燕山期岩浆改造而形成的热液交代型矿床。更多还原

【Abstract】 Cited Dongguashan sedimentary hydrothermal diplogenetic stratified copper deposit as an example,and based on the studies of regional geological settings and deposit geological characteristics of Dongguashan stratified copper deposit;the authors discussed the genesis of stratified copper deposit.It is concluded that the mineralizing processes of Dongguashan copper deposit could be divided into two stages:stratified sedimentary deposit or proctored layer formed in late Devonian to late Carboniferous periods as its first stage;the pre-existed proctored deposit was diplogenetic alternated by magmatic hydrothermal fluid derived from Yanshanian magmatic activities as its second stage.更多还原
