黔东南天柱县巴宗金矿区地质、化探特征及其找矿潜力

Geological and Chemical Prospecting Features and Prospecting Potential of Bazong Gold Mine in Tianzhu County of Southeast Guizhou Province

巴宗矿区位于黔东南天柱县境内,具有良好的金矿成矿地质条件。在前人1∶20万所圈定的化探异常的基础上,通过开展1∶5万水系沉积物测量和1∶1万土壤地球化学以及1∶5万构造地球化学测量工作,分析样品中Au、As、Sb、Hg、Cu、Pb、Zn等元素含量,在综合考虑异常区地质概况,各元素异常的空间分布特征、异常元素强度和规模,共圈定6处综合异常(水系沉积物化探异常5处,土壤化探异常1处),为后续的矿产勘查提供了勘探靶区。通过对巴宗矿区地质及化探特征的综合分析,认为该地区具有金矿产资源勘查的潜力。

Bazong gold mine is located in Tianzhu County of southeast Guizhou province, and it has good geological conditions for gold mineralization. On the basis of delineated 1 ： 200 000 geochemical anomalies, and by conducting a 1：50 000 stream sediment survey and l： 10 000 soil geochemical survey work, the content of Au, As, Sb, Hg, Cu, Pb, Zn and other elements in samples was analyzed. Considering the geological situations of abnormal areas, the spatial distribution characteristics, strength and sizes of abnormal elements, 6 comprehensively abnormal places were delineated （5 from the stream sediment geochemical anomalies and 1 from soil geochemical anomalies） , serving as target areas for subsequent mineral exploration. Based on the comprehensive analysis on the geological and geochemical characteristics of Bazong mining area, it is believed that the region has the potential of prospecting for gold mineral resources.
