摘　　要：对织金矿区晚二叠世碎屑岩与碳酸盐的沉积特征信岩石中的B、Ga、Sr、Ba的含量与其它微量元素含量的分布,进行了对比分析,并且结合上述地层中的生物组合及化石进行了地球化学特征与沉积环境的分析与探讨从而推断当时的沉积环境为过渡相偏海相的沉积特征图2,表3。This paper analyzes the sedimentary characteristics of clastic rock and carbonate rock of upper Permian in Zhijin mining area,compares the content and distribution of B,Ga,Sr,Ba and other trace elements in these rocks.On this basis,combining with the assemble of fossil organism,the author discusses the geochemical characteristics and sedimentary environment.It is concluded that the sedimentary environment at that time was transitional facies by marine facies.2figs.,3tabs.,4refs.
