| 摘 要： | 对塔里木盆地阿瓦提-满加尔坳陷三叠—侏罗纪的沉积物源从时空变化上进行了探讨.利用砂岩和砾岩的成分分析, 从纵向上研究沉积物源的演化, 认为包括沙雅前陆隆起在内的毗邻造山带的隆升是随着古生界的揭露而逐步隆起的; 利用岩相展布, 从平面上分析了沉积物源的变迁, 认为包括沙雅前陆隆起在内的周边物源区是与沉降中心同步发生反时针旋转的, 这种旋转与塔里木盆地的顺时针旋转有关

| Abstract: | This paper is focused on the
provenance evolution and migration of Triassic and Jurassic Awat-Manjia'er depression of
the Tarim basin. The compositional analysis of sandstone and conglomerate suggests that
the adjacent orogenic zone including the Shaya forebulge was gradually uplifted with the
exhumation of the Paleozoic. The analysis based on lithofacies distribution suggests that
the surrounding provenances including the Shaya forebulge rotated anti-clockwise
contemporaneously with the subsidence center. This rotation may be caused by the clockwise
rotation of the Tarim basin. |
