摘要 以往针对保山地区三叠系大水塘组中硅质岩的研究甚少,在1∶5万金鸡村、板桥街两幅区域地质调查项目中,通过研究硅质岩的沉积地球化学特征表明,保山地区三叠系上统中的硅质岩为热水沉积,形成于大陆边缘构造背景。 Chert in Baoshan Area Triassic series Dashuitang Formation little, in 1:50000 Jinji Village, the Panehiao Street two regional geological survey project in chert Sedimentary geochemistry through research thathydrothermal deposition in Baoshan Area in the upper Triassic series s chert formed in the background of the continental margin.
