【摘要】：在野外剖面观测和样品分析测试的基础上,以地球化学特征分析为依据,研究了柯坪冲断带下寒武统肖尔布拉克组下段碳酸盐岩烃源岩古氧相。柯坪冲断带寒武系肖尔布拉克组下段发育烃源岩,横向分布稳定,主要发育于局限台地相沉积环境。寒武系肖尔布拉克组下段烃源岩有机质碳含量较高,有机质类型为Ⅰ-Ⅱ型,达到了高成熟阶段,具备生烃潜力。肖尔布拉克组烃源岩沉积时期,古生产力较高,为有机质沉积提供了良好的物质基础。V/(V+Ni),U/Th和δCe等参数指示出其为缺氧的沉积环境,为有机质的保存提供了有利的条件,具有一定的勘探潜力。
[Abstract]:On the basis of field profile observation and sample analysis and geochemical analysis, paleo oxygen facies of carbonate source rocks in Lower Cambrian Scholburak formation of Keping thrust belt are studied. The lower member of Cambrian Scholburak formation in Keping thrust belt developed source rocks with stable lateral distribution and mainly developed in the confined platform facies sedimentary environment. The source rocks of lower Cambrian Scholburak formation have high organic carbon content and organic matter type 鈪，
