摘要
清江铁金矿床位于湘中地区,出露铁矿体和金矿体两种矿体。铁矿体呈层状赋存于震旦系下统江口组中,具有典型的“江口式”铁矿床特征,并经历多期区域变质作用,形成沉积变质型铁矿床。金矿体富集于江口组中的节理裂隙及层间破碎带等,受东西向构造控制,为岩浆热液型金矿床。
The Qingjiang iron-gold deposit is located in the central Hunan area,and there are two types of iron ore and gold ore bodies.Iron ore bodies exist in layers in the Lower Sinian Jiangkou Formation,with typical"Jiangkou"iron deposit characteristics,and undergo multi-stage regional metamorphism to form sedimentary metamorphic iron deposits.The gold ore body is enriched in the joint fissures and interlayer fracture zones in the Jiangkou Formation.It is controlled by the eastwest structure and is a magmatic hydrothermal gold deposit.
