| 摘 要： | 从柴达木盆地西北地区古近纪古—始新世、渐新世古地形、古物源及沉积体系构成与分布的演变方面,剖析了柴西古近纪沉积充填过程及控制因素。受阿尔金断裂在新生代走滑过程中近南北向挤压分量的作用,柴达木盆地西部地区形成了多隆多坳的地形格局。下干柴沟组沉积期（约60～40 Ma）,随阿尔金山的快速隆升,在阿尔金山前形成数个沉降中心,...

| Abstract: | Quantitative studies on the Paleogene sedimentary filling history and analysis of its controlling factors were carried out based on studies of topography,sediment provenance,constitution and distribution of sedimentary system in Qaidam basin.Western region of Qaidam basin can be divided into several secondary uplifts and depressions controlled by Cenozoic strike-slip process of Altyn Tagh.In Xiagancaigou depositional stage(about 60~40 Ma),with the fast uplift of Altyn Tagh,several subsidence centers were cr... |
