AN APPROACH TO MAJOR TECTOGENESIS OF TARIM BASIN

摘要: 塔里木运动造就了现今盆地构造格局的最初雏形。加里东中期运动使塔里木由寒武一奥陶纪时的克拉通内拉张盆地转化为志留一泥盆纪挤压盆地,天山早期运动、天山晚期和末期运动以及印支运动产生的3次构造反转、块断活动、隆升剥蚀和准平原化作用,对塔里木构造变形有着重大影响。喜马拉雅运动使盆缘山系强烈挤压缩短和隆升剥蚀,盆地发生强烈挠曲沉降。塔里木盆地主要构造运动的发生与板缘的伸展张裂、俯冲消减和碰撞闭合作用有关。Abstract: It is indicated that the embryo of modern Tarim basin was brought about by Tarim orogeneses. The midCaledonian movement resulted in that the introai-cratonic extensional Tarim basin during Cambrian-Ordovician transformed into a compressional basin during Silurian-Devonian. Because of early-Tianshan, and late-Tianshan orogeny and Indosinian orogeny, three tectonic inversions, block-faulting, elevation, erosion and peneplanation occurred, which affected the structural deformation of the Tarim to a large extent. Owing to the Himalayan movement, the Tianshan and Kunlun mountain belts around the basin rapidly compressed, shortened,uplifted, and denuded, and an intense flexural subsidence of the Tarim continental lithosphere took place. The major tectonic movements of the basin are related to streching, rifting, subduction and collision and closing atthe plate margins.
