| 摘 要： | 经过近几年的勘探工作新疆中生代盆地取得了大量物化探资料和钻井、测井、分析化验等地质资料．这些资料的积累，为深入探讨新疆中生代盆地的演化过程提供了丰富信息．应用含能源盆地沉积学研究的工作方法对盆地中生界格架、沉积体系类型及其展布、盆地的充填样式等方面进行了探讨．新疆侏罗纪盆地具有许多类似的特征．总体表现为张性构造背景条件下的盆地类型．这些盆地已成为残留盆地，原始沉积物源离目前盆地边界较远，大部分边缘相已被天山隆起过程中剥蚀，而非因天山逆冲掩覆．新疆侏罗纪呈现三隆四坳的古地理格局．分别为塔北、南天山、北天山隆起带和托云-和田、库车-焉耆、伊犁-乔尔玛、准噶尔-吐哈沉积坳陷带．各盆地沉积环境基本类似，多为浅水湖盆的河流．三角洲沉积环境．

| Abstract: | For exploration in the last few years, many data of seismic, physical and chemiscal exploration, and borehole data of the Mezosoic in Xinjiang have obtained. Based on these datases, we can analyses deeply the the evolvement of Mesozoic basin in Xinjiang have obtained.Based on these data,we can analyses deeply the evolution of Mesozoic basin in Xinjiang. In this paper, the great quantity of geology data will be brought forward and investigated for the filling style of the basins and the sedimentary tracts by the methods of sedimentology investigating in energy basin. There are many same characteristics about the basins in Xinjiang,most of the basins are the extensional basins and relic basins.The source area is far away from the margins of the basin.The marginal faults were mostly erosioned due to the uplift of the Tianshan mountains but overthrust by the faults.The framework of the palaeogeography represents as three upheavals and four depressions, they are Tuoyun and Hetian,Kuqa and Yanqi,Yili and Qiaoerma, Zhungeer and Tuha depressions, and Tazhong, south Tianshan, and north Tiansh rises.The controlling factors of sedimentary process in terrestrial basin are the structure , type and distribution of sedimentary system , as well as the type of Mesozoic prototype basin.Two Jurassic coal segment occurs in Xinjiang,which slightly differ in layers but has similar characteristic in forming environment.The coal of the early Jurassic,which belong to lower sequence ,is mainly formrf in terrestrial river coal environment. |
