摘　　要：钡矿资源是重庆市优势矿种资源之一,赋矿层位与下寒武统巴山组关系密切,区域找矿前景巨大。本文以重庆城口县巴山钡矿床为研究对象,分析其矿床地质特征及矿床成因。研究表明:矿层赋存于下寒武统巴山组二段,由3个矿层组成;巴山钡矿床的矿石类型较复杂,可划分为5个自然类型;矿床的形成经历了生物富集和沉积作用阶段,钡物质析出和迁移阶段,毒重石(重晶石)富集成矿阶段,研究结果可为区域找矿勘查工作提供参考。Barium ore is one of the dominant mineral resources in Chongqing.The ore bearing horizon is closely related to the Bashan formation of lower Cambrian.This paper analyzed the geological features and genesis of Bashan barium deposit in Chengkou County,Chongqing.The results showed that the ore bearing horizon occured in the second member of Bashan Formation of lower Cambrian and were composed of three ore beds.The ore types of Bashan barium deposit were complex and were divided into 5 natural types.The formation of the deposit experienced the stages of bioconcentration and sedimentation,barium material precipitation and migration,and witherite(barite)enrichment and mineralization.The results can provide reference for regional prospecting work.
