摘要
且溪科铅锌矿位于湖南省保靖县。区内倒转褶皱和断裂构造彼此贯通,形成良好的导矿构造系统,对区内铅锌矿的控制最为明显。铅锌矿体呈似层状形态大致顺层产于寒武系下统清虚洞组灰色中层夹薄层条带状粉—细晶云岩、砾屑白云岩和层间碎裂岩、角砾岩内。矿区铅锌矿床的形成是区域构造、矿区地质构造、沉积建造、热液活动等多种地质作用的综合产物,其中矿区地层岩性与岩相、构造是本矿床成矿控制的主要因素。位于麻栗场断层上盘褶皱构造内的寒武系下统清虚洞组上段白云岩,是该区铅锌矿的主要找矿方向,有希望找到大中型铅锌矿床。
There is a good ore-controlling structure system at Qiexike lead and zinc mine situated at Baojing country of Hunan province which the overturned fold and fracture structure are run-through in it.The stratiform-like ore body of the lead and zinc mine is from Qingxudong gray middle and folium banded microlite and conglomerate dolostone, as well as the cataclasite and breccia in Lower cambrian system.The deposit formation of the lead and zinc mine is the combine of region structure, geological structure of the ore district, sedimentary formation and thermal activity. The critical factor of the minerogenetic control in the ore district is lithology and lithofacies of stratum and structure. As the main exploration orientation for the lead and zinc mine of this district, the Qingxudong upside dolomite in the fold structure of Ma Lichang fault in upside of lower cambrian will find the largr-medium scale lead and zinc deposit.
