塔里木新元古代-古生代沉积盆地演化

塔里木盆地位于中国西北新疆维吾尔自治区南部，夹持在天山与昆仑山褶皱带和阿尔金山之间，是一个长期发展形成的大型叠合盆地.在综合研究前人资料的基础上，通过对塔里木地区岩石地层、沉积建造的对比分析，划分出塔里木新元古代-古生代的被动陆缘、夭折裂谷、碳酸盐岩台地、碎屑岩陆表海、残余海盆、混积陆表海、陆内裂陷盆地、前陆盆地共8种沉积盆地类型，并分析盆地形成演化的大地构造环境:新元古代早期，塔里木进入稳定的盖层发展阶段；青白口纪发育裂谷和被动陆缘，南华纪-早震旦世发育夭折裂谷和大陆冰川；古生代主要发育碳酸盐岩台地、碎屑岩陆表海和混积陆表海；受北侧哈萨克斯坦-准噶尔板块碰撞的影响，南天山石炭纪洋盆于晚石炭世-早二叠世末俯冲消减；中二叠世始，塔里木大部分演变为前陆盆地. 

Evolution of Sedimentary Basins in Tarim during Neoproterozoic-Paleozoic

Tarim basin, located in southern Xinjiang Uygur Autonomous Region of Northwest China, held among the Tianshan, Kunlun and Altun fold belts, is a large, superimposed basin which has a long evolutional history. Based on the comprehensive study of the previous results, we conduct a comparative study of lithostragraphy and sedimentary, and divide the Tarim area into 8 types of sedimentary basin during Neoproterozoic-Mesozoic, including passive continental margin, failed rift, carbonate platform, clastic epeiric sea, residual sea, mixed clastic-carbonate epeiric sea, inland graben basin, and foreland basin.The tectonic environments of basin formation and evolution are analyzed in this paper: Early Neoproterozoic, Tarim turned into stable stage of cover development.During Qingbaikouan, rift and passive continental margin were developed.Nanhua-Early Sinian, mortality rift and continental glaciers were developed.Carbonate platform, clastic epeiric sea and clastic-carbonate epeiric sea mainly developed during Paleozoic. The collision between Tarim and Kazakhstan-Junggar plate led to later subduction of the southern Tianshan oceanic basin of Carboniferous at the Late Carboniferous-Early Permian. At the beginning of Middle Permian, most of the Tarim evolved to foreland basin.
