| 摘 要： | 对可可西里中新统五道梁群油页岩研究表明：油页岩有机质丰度中等一高；有机质类型以腐泥型（Ⅰ）-腐殖腐泥型（Ⅱ，）为主。有机质的热演化以低成熟为主；总体上为较好的烃源岩，中新世时可可西里盆地为封闭、干热的以碳酸盐岩沉积为主的盐湖盆地。封闭与还原性静水环境为有机质的堆积和转化形成油页岩提供了条件。

| Abstract: | The examination of the abundances and types of organic matter and levels of thermal evolution of the oil shales from the Wudaoliang Group in the Zonag Lake area in the Hoh Xil Basin shows that the organic matter is characterized by moderate to high abundances, sapropelic type （I） - humosapropelie type （ H t ） organic matter and low maturity, indicating potential source rocks. The Hob Xil Basin was once an enclosed carbonate-dominated salt lake basin in the xerothermic conditions during the Miocene. These enclosed and reduced stillwater conditions may facilitate the accumulation of organic matter and formation of the oil shales in the study area. |
