| 摘 要： | 在松辽盆地晚白垩系青一段优质源岩中检测出了芳基类异戊二烯烃化合物，该类化合物以低碳数为主，主要分布在C13~C23之间，最高含量可占芳烃馏份的30%以上。该类化合物的检出以及根据饱和烃生物标志化合物特征分析，认为青一段源岩沉积时期水体具有盐度分层，湖底为微咸—半咸化、强还原的、富硫的环境，有机质除了以藻类贡献为主外，还有绿硫菌的贡献。芳基异戊二烯化合物检出和分布反映了古松辽湖在青一段沉积时期可能存在海侵，海侵方向从盆地东南向西北。

| Abstract: | Aryl isoprenoids have been detected in late Cretaceous shale in Qn1,Songliao basin. It range from C13 to C23,and these compounds have a high concentration in some samples, the highest concentration can be above 30% of aromatic hydrocarbons. These samples are distributed in Chaochang area in southeast Songliao Basin. Aryl isoprenoids and some saturated hydrocarbon biomarkers suggested that the source rocks were deposited under a brackish and reducing and sulphate or sulphied rich water .The algae and Chlorobiaceae are the main source of organic matter in source rocks.The distribution of Aryl isoprenoids indicated that there was a marine transgressional event in Songliao Lake during the late Cretaceous and its direction may be from the southeast to northwest. |
