摘要/Abstract

摘要： 黔北桑木场背斜位于上扬子地块黔北隆起区毕节弧形褶皱带与赤水克拉通盆地的交汇部位，属于有利的铅锌成矿区带。区内铅锌矿的赋矿层位主要有震旦系灯影组、寒武系清虚洞组、高台组及石冷水组，矿体多产于背斜核部并受断层或裂隙控制。通过对地层岩性特征、地表矿化特征、控容矿构造特征、化探异常特征、物探异常特征等进行综合研究，选择在成矿有利地段进行了工程验证，为进一步开展桑木场背斜铅锌矿深部找矿工作提供了思路。

Abstract: The Sangmuchang anticline in northern Guizhou is located at the intersection of the Bijie arcshaped fold belt and the Chishui craton basin in the northern uplift of the Upper Yangtze block,which belongs to the favorable leadzinc deposit metallogenic zone.The orebearing horizons of leadzinc deposits in the area mainly include the Sinian Dengying Formation,Cambrian Qingxudong Formation,Gaotai Formation,and Shilengshui Formation.Ore bodies are mostly produced in the anticline core and controlled by faults or fissures.Through comprehensive research on formation lithology characteristics,surface mineralization characteristics,volumecontrolling ore structure characteristics,geochemical anomaly characteristics,geophysical anomaly characteristics,etc.,the project is selected to be verified in favorable areas of mineralization,which can provide idelas for the next adeep prospecting work in Sangmuchang anticline leadzinc deposit.

Key words: Leadzinc deposit,Deep prospecting,Engineering verification,Case analysis
