新疆的库车—拜城—阿克苏一带,广泛沉积中、新生代沉积,从沉积物组合、分布范围等特点考虑,三叠系至下第三系的沉积基本是在天山山前拗陷范围内的盆地中进行的,特别是早第三纪时期,浅水盆地蒸发岩相更为明显,而至晚第三纪,边缘凹陷的特点才逐渐表现出来,因此,本文将这一范围仍称之为库车盆地。 Xinjiang Kuqa - Baicheng - Akesu area, extensive deposition of Mesozoic and Cenozoic sediments, sediment assemblage, the distribution range and other characteristics, the Triassic to the Lower Tertiary deposition is basically within the Tianshan piedmont range , Especially in the early Tertiary period, the evaporite facies in shallow basins became more obvious. By the late Tertiary, the characteristics of marginal depressions gradually showed itself. Therefore, the scope of this article is still referred to as Kuqa Basin.
