【摘要】：在野外剖面觀測和樣品分析測試的基礎上,以地球化學特征分析為依據(jù),研究了柯坪沖斷帶下寒武統(tǒng)肖爾布拉克組下段碳酸鹽巖烴源巖古氧相。柯坪沖斷帶寒武系肖爾布拉克組下段發(fā)育烴源巖,橫向分布穩(wěn)定,主要發(fā)育于局限臺地相沉積環(huán)境。寒武系肖爾布拉克組下段烴源巖有機質(zhì)碳含量較高,有機質(zhì)類型為Ⅰ-Ⅱ型,達到了高成熟階段,具備生烴潛力。肖爾布拉克組烴源巖沉積時期,古生產(chǎn)力較高,為有機質(zhì)沉積提供了良好的物質(zhì)基礎。V/(V+Ni),U/Th和δCe等參數(shù)指示出其為缺氧的沉積環(huán)境,為有機質(zhì)的保存提供了有利的條件,具有一定的勘探潛力。
[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，
