他什店煤田位于库尔勒市东北十八公里,焉耆中新生代沉积盆地西南缘.盆地南北两侧为东西向构造带所限,西南和东北两侧为北西西向构造带所截,形成一个轴向呈北西向延伸的菱形山间盆地.其中沉积了三叠系、侏罗系、第三系和第四系.新生界与侏罗系呈不整合接触.侏罗系主要出露于盆地西南侧,在哈满沟、他什店一带,元古界变质岩系直接掩覆其上.中生代以来,该区经过多期构造变动,不同期次的构造彼此迭加,相互干扰,构造较为复杂.该区经过几年的地质勘探工作,对煤田内出现几组不同期次、不同方向的构造形迹进行了研究,初步搞清构造分布规律,扩大了煤田范围,证实勘探区是一个大型煤田.
The Tashidian Coalfield is located 18 kilometers northeast of Korla to the southwestern margin of the Mesozoic-Cenozoic sedimentary basin in Yanqi, and is restricted by the east-west tectonic belt on both sides of the basin, with the northwestern-western tectonic belt cut off on both sides of the southwest and northeast to form an axial Triassic, Jurassic, Tertiary and Quaternary sediments were deposited in a rhombic inter-basin basin extending from north to west.The unconformity contact between the Mesozoic and the Jurassic was observed in the Cenozoic.The Jurassic mainly appeared in the southwestern part of the basin In the area of Hamangou and Shushidian, the Proterozoic metamorphic rocks directly cover the surface of the Paleozoic.After the Mesozoic, the structure of the Paleozoic passes through multiple stages of tectonic movements, and the structures of different periods overlap and interfere with each other, resulting in a complex structure. After several years of geological prospecting work in the area, several sets of coalfield structures with different periods and directions have been studied. The tectonic distribution law has been initially clarified and the coalfield has been expanded to confirm that the exploration area is a large-scale coalfield.
