贵州省赫章县白腊厂观音山铅锌矿床地质特征及控矿条件分析

通过对赫章县白腊厂观音山铅锌矿床地层、构造及矿体特征的分析,从构造、含矿岩性、物源等方面对该矿床进行了控矿条件进行研究。矿床主要受北西向和北北东向两组构造控制,该构造既为含矿热液的导矿构造,也为该区铅锌矿体的容矿构造。矿体主要产于碳酸盐岩地层中,层控特征明显。成矿物质可能主要来源于地层,但有深部地壳或地幔硫的混合。综合研究表明,该矿床属于层控矿床,北西向和北北东向两组构造以及旁侧小褶皱分布区域可能为成矿远景区。

Analyses on Geologic Characteristics and Ore Control Factors of Guanyinshan Lead-zinc Deposit in Bailachang,Hezhang, Guizhou

By analysis the strata, structure and orebody of Guanyinshan lead-zinc deposit in Bailachang, the ore control factors of this deposit are studied in the structure, ore-bearing property and material source. The orebody is controlled by NW structure and NNE structure, this structure is not only the leading structure of ore-bearing geotherm but also ore-hosting structure of lead-zinc orebody. The orebody mainly occur in carbonate rock strata and the stratabound feature is obvious. The mineral material perhaps mainly came from strata, but some mixture of deep crust and mantle sulfur. The research shows this deposit is stratabound deposit, NW, NNE structure and nearby small fold area may be the prospecting area.
