吉林红太平铜多金属矿床地质特征及成因探讨

Geological features and genesis of Hongtaiping Cu-polymetallic ore deposit of Jilin Province

红太平铜多金属矿主要赋存于下二叠统庙岭组下岩段交互层中,矿体呈整合层状或扁豆状产于一定层位,交互层为矿源层。成矿物质来源于海底火山活动,外生沉积作用不明显。根据矿石的结构、构造反映了矿石原始沉积及同生特点和后期热液改造叠加特点。矿(体)化与侵入岩无成因联系。因此认为,该矿床为海底火山-沉积变质后改造矿床。

Hongtaiping Cu-polymetallic deposits mainly occurs in the alternating layer below rock section of Carboniferous-lower Permian Miaoling Formation.Ore body occurrence in concordant bedding layer or omphalopter certain horizon,alternating layer are source bed.Metallogenic material derive from submarine volcano activity,and exogenetic deposition is not obvious.The ore structure and formation reflects the original sedimentary features of ore,consortium and later hydrothermal superimposition features.Mineralization（ore body） and intrusive rocks without genetic connection.Therefore,this deposit is transformation deposits after submarine volcano-sedimentary metamorphism.
