| 摘 要： | 以剖面和测井资料为依据,在研究了库车地区古近系地层的岩性组合、相序特征、沉积构造等岩性特征基础上,认为该区古近纪时期总体上为河流--湖泊沉积环境.库车地区构造运动、海平面变化、气候条件和物源供给等因素相互作用,共同控制了该区的沉积演化格局,分别发育了冲积扇、扇三角洲、辫状河三角洲、曲河流三角洲、滨浅湖和海湾、泻湖等沉积...

| Abstract: | This paper makes research on lithologic character association,sedimentary facies and sedimentary structure of the Paleogene in the Kuqa depression,Tarim basin based on profile and logging data.The research indicates that the Kuqa depression in the Paleogene was in a fluvial-lacustrine environment.The sedimentary pattern was controlled by tectonism,fluctuation of sea level,climate and provenance.Sedimentation in the Kuqa depression in the Paleogene may be divided into 2 stages. |
