摘要
赋层于泥盆系中统棋梓桥组中段含生物碎屑白云岩中的铅锌矿床是近年来在临武长冲新发现的层控型铅锌矿床,作者在综合分析矿床地质特征和成因的基础上,认为前泥盆系矿源层经后期地下水热液或深循环热卤水溶液热液成矿;成矿经历了沉积-成岩阶段和后生交代阶段,属沉积+改造层控矿床。
The Lead-Zinc deposit in the bioclastic dolomite in the middle part of Qiziqiao formation of middle Devonian is a new stratabound lead-zinc deposit discovered in recent years in Changchong,Linwu.On the basis of comprehensive analysis of the geological characteristics and genesis of the deposit,the authors believe that the source bed of pre-Devonian system is mineralized by the later groundwater hydrothermal solution or the deep circulation hydrothermal brine solution hydrothermal solution;the mineralization has gone through the sedimentary diagenetic stage and the epigenetic metasomatism stage.It belongs to sedimentary + reformed stratabound deposit.
