Geologists agree that the collision of the Indian and Asian plates caused uplift of the Tibet Plateau. However, controversy still exists regarding the modes and mechanisms of the Tibetan Plateau uplift. Geology has recorded this uplift well in the Qaidam Basin. This paper analyzes the tectonic and sedimentary evolution of the western Qaidam Basin using sub-surface seismic and drill data. The Cenozoic intensity and history of deformation in the Qaidam Basin have been reconstructed based on the tectonic developments, faults growth index, sedimentary facies variations, and the migration of the depositional depressions. The changes in the sedimentary facies show that lakes in the western Qaidam Basin had gone from inflow to still water deposition to withdrawal. Tectonic movements controlled deposition in various depressions, and the depressions gradually shifted southeastward. In addition, the morphology of the surface structures in the western Qaidam Basin shows that the Cenozoic tectonic movements controlled the evolution of the Basin and divided it into （a） the southern fault terrace zone, （b） a central Yingxiongling orogenic belt, and （c） the northern fold-thrust belt; divided by the XI fault （Youshi fault） and Youbei fault, respectively. The field data indicate that the western Qaidam Basin formed in a Cenozoic compressive tectonic environment caused by the India--Asia plate collision. Further, the Basin experienced two phases of intensive tectonic deformation. The first phase occurred during the Middle Eocene--Early Miocene （Xia Ganchaigou Fm. and Shang Ganchaigou Fro., 43.8- 22 Ma）, and peaked in the Early Oligocene （Upper Xia Ganchaigou Fro., 31.5 Ma）. The second phase occurred between the Middle Miocene and the Present （Shang Youshashan Fro. and Qigequan Fro., 14.9-0 Ma）, and was stronger than the first phase. The tectonic--sedimentary evolution and the orienta- tion of surface structures in the western Qaidam Basin resulted from the Tibetan Plateau uplift, and

The Lishu Depression， located in the southeastern region of the Songliao Basin， exhibits diverse fault types and complex tectonic evolution characteristics， however， the slipping direction and activity duration of strike-slip faults， as well as the overall tectonic evolution process remain unknown. This study applied a method for determining the slipping direction and activity duration of strike-slip faults， and reconstructed the tectonic evolution process of the Lishu Depression using balanced cross sections. The determination of the slipping direction of strike-slip faults was based on the analysis of the dislocation distance of a specific set of strata on two fault walls within the anticline zone， and the activity duration of strike-slip faults was defined by the sedimentary period of the strata cut by faults， and the variation characteristics of formation thickness. The slipping direction and activity duration of the strike-slip faults in the study area suggest that the depression experienced a left-lateral strike regime during the sedimentary periods of 135–131.8 and 124.5–112 Ma. However， during the sedimentary periods of the Yingcheng Formation (131.8–124.5 Ma)， the region was influenced by a right-lateral strike background. The study area experienced a continuous process of extension from 145.6 to 124.5 Ma， and compression commenced from the depositional period of the Nenjiang Formation (88.5 Ma)， as shown by negative values of the extension rate. The findings of this study hold significant theoretical implications for the identification of the slipping direction and distance of strike-slip faults within comparable depressions. Moreover， these results have practical implications for further hydrocarbon exploration in the Lishu Depression.

松辽盆地梨树断陷下白垩统储层内发育不同类型沥青,沥青的形成时间及成因尚不明确,沥青发育特征与天然气成因关系密切,研究沥青与油气成因的关系有助于明确下一步天然气勘探方向。为此,综合利用流体包裹体观察及测温、沥青激光拉曼光谱、天然气组分等分析手段,研究不同类型沥青的赋存状态、成熟度、形成时间及成因,并综合判识了该区油气藏类型,明确了沥青发育程度与油气成因的关系。研究结果表明:(1)梨树断陷下白垩统储层内存在碳质沥青和沥青质沥青两类沥青。碳质沥青呈规则状半充填或完全充填于粒间孔内,不具荧光,拉曼光谱可见明显的D峰和G峰;沥青质沥青呈脉状充填于裂缝内或不规则状充填于孔隙内,具棕褐色荧光,拉曼光谱中D峰弱发育或不发育。(2)碳质沥青成熟度较高,为原油在上白垩统嫩江组沉积期裂解形成;沥青质沥青反射率较低,为成藏期油气运移分异形成。(3)研究区油气藏类型多样,后五家户、孤家子和金山等地区以气藏为主,皮家、十屋、四五家和八屋等地区以气藏和无油环凝析气藏为主,苏家屯和秦家屯等地区以带小油环凝析气藏及无油环凝析气藏为主。结论认为,碳质沥青发育程度与天然气成因密切相关,后五家户、孤家子和金山等地区的气藏碳质沥青含量低,为腐殖型干酪根裂解形成的煤型气;皮家、十屋、四五家和八屋等地区的气藏和无油环凝析气藏碳质沥青含量较高,为干酪根裂解和原油裂解混合成因;苏家屯和秦家屯地区带小油环凝析气藏和无油环凝析气藏碳质沥青含量高于0.25%,主要为原油裂解成因。
