英文摘要	In the northern part of Tarim basin, the Tabei Rise is one of the tectonic units richest in oil and gas accumulation. Based on the Paleozoic intra-craton uplift, it developed into the forebulge of Kuqa peripheral foreland basin in terminal Permian-Early Triassic. During Cenozoic it subsided entirely and became a residue of paleo-uplift buried beneath the foredeep of the intracontinental foreland basin in northern Tarim. The existing division of the tectonic units of Tabei Rise cannot accurately reflect its real tectonic framework. New evidence indicates that the redivision of the tectonic units of Tabei Rise is likely: (1) to cancel the Halahatang Sag and Caohu Sag and redefine the Lunnan Lower Uplift, which includes the former Lunnan Lower Uplift, Halahatang Sag and the Northern part of Caohu Sag. The redefined Lunnan Lower Uplift is a large anticlinal nose developed in pre-Carboniferous. The southern part of the former Caohu Sag reallocates to the Northern Depression. (2) The -6500m altitude contour of the Middle Ordovisian top surface is considered to be the southern boundary of Tabei Rise. The contour fairly well reflects the tectonic configuration of the Tabei Rise, particularly the configuration of the large anticlinal nose. (3) The Luntai Uplift and Yingmaili Lower Uplift are delineated clearly by a Paleozoic structure line composed by the Yangtal-Yingmai 8 fault and the Yingmai 4-Yingmai 1 anticline. On the two sides of this line, each Paleozoic reflecting layer exhibits remarkable abrupt throw, and the magmatism, stratigraphy, structural deformation and evolution history are also contrasted obviously. The redivision of Tabei Rise includes five secondary tectonic units, i.e. the Korla nose-shaped uplift, Luntai Uplift, Lunnan Lower Uplift, Yingmaili Lower Uplift and Akesu Nose-shaped Uplift. This paper will provide the definition and scope of the Tabei Rise and its secondary tectonic units as well as brief description of their evolution.
