| 摘 要： | 新疆西昆仑汗铁热克一带地处塔里木盆地西南缘，构造上属塔里木盆地与西昆仑造山带的结合部位，侏罗纪地层包括积莎里塔什组、康苏组、扬叶组、塔尔尕组和库孜贡苏组。根据岩性、颜色、粒度分析及沉积相标志等方法，将汗铁热克一带侏罗纪沉积环境与沉积相划分为冲积扇、扇三角洲和湖泊相，其沉积特征为侏罗纪早期快速充填，中期稳定沉降，晚期短暂的沉积间断后充填，并系统分析了研究区在整个侏罗纪沉积环境演化规律。

| Abstract: | The Hantiereke area, Xinjiang is located in the southwest edge of the Tarim basin as well as the junction between the West Kunlun orogenic belt and the Tarim basin, where Jurassic strata consist of Shalitashi Formation, Kangsu Formation,Yangye Formation, Targa Formation and Kuzigongsu Formation. Based on lithology, color, grain-size and sedimentary facies, the deposit setting and sedimentary facies of this area can be divided into alluvial fans, fan delta and lake facies, which are characterized by rapid filling during the early Jurassic, stable subsidence in the middle Jurassic and continual filling after a brief depositional break in the late Jurassic. In addition, the evolution of depositional environment throughout the Jurassic had been analyzed systematically for the study area. |
