摘要
岩石层会聚地区，形变作用的体现是以造山带与盆地正负相伴生组成的地质景观为特色，青藏特提斯“造山拼合体”后陆的塔里木盆地就是一典型实例．笔者依据盒内区域地震地质解释断面反映的盆地实体形变特征及有限的钻井资料，结合盆缘地质露头，剖析塔里木盆地构造地史及其形变风格．认为，塔里木盆地构造演化受控于古亚洲与特提斯两大构造城。因其形变风格各异，导致盆内垂向上呈古褶隆与类前陆和新造山带与前陆盆地双层地质结构。
he deformation produced the geological landscape accompanied with orogen and basinin lithostratigraphic convergence zone and Tarim basin, as a typical instance of the Qinghai-Xijang (Tibet) Tethys orogenic backland. The tectonic history and deformational style of Tarim basin has been analysed based on regional geoseismic sections well data and outcropsin this paper. The writer considered the tectonic evolution of Tarim basin to be controlled byevolutionary process of the Paleo-asiatic tectonic domain and Tethys tectionic domain, and tobe so different in deformational style of Tarim basin that the two-storied geological structurecomposed of the Paleo-culminatuion/quasi-foreland and Neo-orogen/fore-land basin is madeon the vetical plane.
