摘要
环江县北山地区铅锌矿均富集在同一地层层位——中上泥盆统,五圩—川山—驯乐NNE向深断裂控制着成矿带,矿床存在大量沉积成岩成矿组构,喷流沉积特征明显。其成矿地质背景、沉积相、礁硅岩套建造、同生断裂活动、赋矿层位等与邻区丹池锡-铅锌多金属矿集区类似,有巨大找矿潜力。
Lead-zinc deposits in Beishan region are located at the same stratum-Middle to Upper Devonian Series(D_2-D_3). The mineralization zone is controlled by Wuxu-Chuanshan-Xunle deep rooted fracture in NNE strike. The deposit is clearly characterized by sedimentation-exhalation,and rich in sedimental,diagenic and mineralized fabrics.There is a large prospecting potentiality in Beishan region because the geological surrounding, sedimentary phase, reefal limestone formation, syngenetic faulting activity and ore bearing layer are similar to the Danchi tin-lead-zinc polymetallic deposit in neighboring area.
