摘　　要：贵州省天柱县大河边重晶石矿床,是全球最大的重晶石矿床,累计提交的重晶石资源储量逾1.8亿吨。重晶石大规模成矿与Rodinia超大陆裂解密切相关,其产出构造背景特殊,位于南华裂谷与铜仁古裂谷的交汇位置。本文从构造背景、矿床地质特征和典型观察点等方面较详细介绍天柱大河边重晶石矿床特征,并选择一些代表性的露头点和钻孔岩矿芯进行观察等。由于具有较强的典型性和代表性,贵州省天柱县大河边重晶石矿床被选为中国地质学会第十七届矿床会议野外考察路线之一。Dahebian barite deposit of Tianzhu county in Guizhou province is the biggest barite deposit of the world which committed barite resource more than 0.18 billion ton totally.The extensive barite mineralization has deep relation with Rodinia supercontinent breakup,the occurrence structural background is special and it located in the joint area of Nanhua rift and Tongren ancient rift.In this paper,it detailed introduced the characteristics of Dahebian barite deposit in the strctural background,geological characteristics and typical observation point,observed some typical outcrops and drilling rock and ore core.Because the typicalness and representativeness,Dahebian barite in Tianzhu county,Guizhou province was selected as one of the survey routes of the 17th Mineral Deposits Conference of the Geological Society of China.
