摘要 贵州铅锌矿主要分布于黔西和黔东地区铅锌矿成矿带上,前人认为属低温热液矿床[1、2]。而新发现的五指山铅锌矿[3],结合区内铅锌矿床特征分析认为,主要为喷流沉积矿床。在黔西地区主要产出于泥盆—石炭系碳酸盐岩地层的4个成矿亚带中,为燕山期产物;而沿五指山北东向展布的一系列铅锌矿、织金—纳雍成矿亚带和黔东铅锌成矿带,产出于震旦—寒武系碳酸盐岩地层,为加里东期产物。该认识对研究贵州省铅锌矿床和指导找矿具重要意义。 Pb-Zn deposits in Guizhou are mainly distributed over the lead-zinc metallogenic belts in west Guizhou and east Guizhou.Geological features of the Pb-Zn deposits in Guizhou show that all the deposits are sedimentary exhalative deposits.The Pb-Zn deposits in west Guizhou occur in the Devonian and Carboniferous carbonate strata which may be divided into 4 metallogenic subzones,being the products in the Yanshanian epoch,while a series of Pb-Zn deposits distributed along NE-trending direction of the Wuzhishan Hill,and in the Zhijin-Nayong metallogenic subzone and the lead-zinc metallogenic belt in east Guizhou occur in the Sinian-Cambrian carbonate strata,being Caledonian products.
