摘要
笔者总结了西昆仑—帕米尔造山带及塔西南前陆盆地板内变形的各类构造模式、构造分带、新生代变形格局及构造演化,提出其新生代板内变形具有弧形构造分段性和阶段性演化的特点,发现了依格孜牙、柯克亚、桑株—杜瓦、卡兹克—阿尔特薄皮弧形推覆构造、齐姆根主弧形构造段及玉力群—克里阳构造段的三角带构造及叶尔羌—棋盘对冲过渡型弧形构造。认为对冲过渡型弧形构造及各弧形构造分段间的斜冲走滑带是塔西南前陆盆地板内变形的特殊产物。
This paper summarizes various structural models, structural belts, Cenozoic deformation frameworks and tectonic evolution concerning intraplate deformation in the West Kunlun - Pamir Cenozoic erogenic belt and Southwest Tarim foreland basin and suggests that the Cenozoic intraplate deformation be characterized by segmentation and stage evolution. The Yigeziya, Kok-yar, Sanju -Duwa and Kazike -Aerte thin-skinned arcuate nappe structures, triangle zones of the Qimugen main segment and Yuliqun - Kiliyang segment and Yarkan - Qipan ramp transitional arcuate structure have been found and it is considered that the ramp transtional arcuate structure of Yarkan - Qipan and oblique thrust/strike-slip faults between various arcuate segments are the special intraplate deformation product of the Southwest Tarim foreland basin.
