摘要
研究了鄂尔多斯奥陶系碳酸盐岩中沥青Ａ和沥青Ｃ的生物标志物特征，表明沥青Ａ和沥青Ｃ之间在生物标志物组成上存在着明显的差异，产生这些差异的原因主要是氧化还原环境、成熟度及粘土矿物含量的不同。结合沉积相分析。
The biomarker characteristics of bitumen A and bitumen C of the Ordovician carbonate rocks in Ordos Basin are studied in this paper. The results show that there are some differences between bitumen A and bitumen C in biomarker compositions because of unlike in its redox environment, maturation and clay minerals content. Combining with sedimentary facies analyses furtherly, the authors inquire into the distribution patterns of bitumen A and bitumen C in different sedimentary environments.
