在钻井、地震及露头资料综合研究基础上，研究塔里木盆地塔河-天山南地区早白垩世亚格列木期源汇系统及沉积体系配置关系，揭示出以雅克拉断凸为界，地层整体具有顶薄翼厚、南北分带的特点，从南、北两侧向隆起超覆，隆起顶部部分地层缺失。该区源汇体系明显受地貌控制，主要发育北部、南部和东部三大物源区，塔河和库车两大物源汇聚中心，围绕塔河汇聚中心形成了雅克拉断凸带短物源形成的扇三角洲群，亚肯、于奇、吉拉克、阿克亚苏及托普台物源形成的辫状河三角洲群。雅克拉断凸对沉积体系的分布具有重要的控制作用。

Based on drilling, seismic and outcrop data, the source-to-sink system and the configuration of sedimenta-ry systems in the Tahe and southern Tianshan areas during the Yageliemu period of the Early Cretaceous were studied. Bounded with the Yakela fault arch and characterized by significant north and south zonality in landform structure, the Cretaceous was thin on the top and thick on the flanks, and was partially missing on the top of the uplift. The source-to-sink system was obviously controlled by landform, developing 3 source areas (northern, southern and eastern) and 2 sink centers (Tahe and Kuqa). Surrounding the Tahe sink center, the fan delta group with the Yakela fault arch short source developed, and the braided delta group with the Yaken, Yuqi, Jilake, Akeyasu and Tuoputai sources de-veloped. The Yakela fault arch played a significant role in sedimentary system distribution.
