| 摘 要： | 西昆仑造山带位于青藏高原的西北缘、塔里木盆地的西南缘, 是中央造山带的重要组成部分, 经历了长期、复杂的沉积-构造演化.叙述了西昆仑造山带5个地层分区出露的岩石地层及其对应沉积盆地类型, 进而对西昆仑沉积盆地演化历史进行了探讨.西昆仑新元古代-中生代的沉积盆地演化过程可划分为如下3个阶段: (1)新元古代大陆裂解、洋壳形成阶段; (2)早古生代-中三叠世板块机制演化阶段; (3)晚三叠世以来陆内演化阶段.

Evolution of Neoproterozoic-Mesozoic Sedimentary Basins of West Kunlun Area |
| |
| Abstract: | West Kunlun orogenic belt is located in the northwest margin of the Qinghai-Tibet Plateau, and in the southwest edge of Tarim basin. This belt is an important part of the central orogenic belt. It has experienced a long and complicated tectonic-sedimentary evolution. This paper presents lithostratigraphy of outcrops in five stratigraphic subregions and their corresponding sedimentary basin types in West Kunlun orogenic belt. The evolutionary history of sedimentary basins in West Kunlun is explored and divided into following three stages from Neoproterozoic to Mesozoic in this study: (1) the stage of continental break-up and the formation of oceanic crust in Neoproterozoic; (2) the stage of plate mechanism evolution in Early Paleozoic-Middle Triassic; (3) the stage of evolution in intracontinental since Late Triassic. |
