| 摘 要： | 松辽盆地白垩系青山口阶下部广泛分布一套富含有机碳的黑色泥岩、页岩沉积,它具有干酪根碳同位素正偏、重排甾烷含量低,普遍存在伽马蜡烷生物标志化合物等有机地球化学特征,代表了白垩纪温室效应时间窗内古湖泊贫氧环境条件下的沉积产物。结合生物地层研究成果,认为青山口阶下部曾发生过古湖泊缺氧事件,其层位大体可与白垩纪古海洋Cenomanian-Turonian界线事件层进行对比,由此提出了松辽盆地青山口阶下部的时代归属于晚白垩世Cenomanian晚期—Turonian早期的新观点。 |
| 关 键 词： | 黑色页岩 碳同位素 生物标志物 缺氧事件 青山口组 白垩系 松辽盆地 |

| Abstract: | The Songliao Basin was a big lake during the mid-Cretaceous,where dark mudstones and shales of the Qingshankou Formation were distributed in the basin.The dark mudstones and shales in the Member 1 of the Qingshankou Formation are of high organic carbon and low diasteranes contents.Organic geochemical characteristics are illustrated by biomarkers of 28-,30-bisnorhopane and gammacerane,and positive excursion of kerogen isotopes.It is suggested that the dark mudstones and shales in the Member 1 of the Qingshan... |
