摘要
以沉积大地构造背景分析为基础,指出塔里木板块南缘由拉张背景转变为挤压,大地构造运动造成的东西向坳隆相间的古地形控制了塔里木盆地内柯坪塔格组的沉积格局和沉积发育史.结合沉积相的精细解释,将柯坪塔格组划分为潮坪—陆棚—潮坪三个沉积演化阶段.
Taking the analysis of sedimentary tectonic background as the foundation, it is indicated that the tectonic background of the southern of the Tarim plate is from tension to compression. The depositional framework and development of Kepingtage For- mation in Tarim Basin have been controlled by the ancient landform elevation caused by tectonic movement with latitudinal alter- nating depressions and uplifts. Combining with fine interpretation of sedimentary facies, Kepingtage Formation may be divided in- to three depositional evolution stages： tidal flat, shelf and tidal flat.
