重点研究了吐哈盆地构造单元的类型、构造属性及其与构造反转之间的关系等相关问题.吐哈盆地的构造单元可归为2种不同类型的体系:坳陷/隆起-凹陷/凸起类型的体系和构造带类型的体系.前者为沉积构造单元,具有同沉积构造的属性.可代表盆地形成时期的伸展性结构与构造;后者则为变形构造单元,具有"后生或次生"构造的属性,反映或代表了后期的构造反转.吐哈盆地"东西分块"应是同沉积期构造格局的表象,"南北分带"则主要是后期挤压与构造反转的结果.由此也进一步证明,吐哈原型盆地属伸展性盆地,后期则因挤压改造而发生了构造反转.前述各种特征则可能是此类构造反转盆地所具有的特殊的地质构造现象.

This paper focuses on such related aspects as the types and attributes of tectonic units, and the relation between die tectonicunits and basin inversion of Turpan-Hami Basin. The tectonic units in Turpan-Hami Basin fall into two systems of different types: diementary tectonic attribute, and represents die extensional framework and tectonics in die formation period of die basin; die latter is diedeformation tectonic unit widi "epigenetic or secondary"tectonic attribute, and reflects die basin inversion in die later stage. In dieTurpan-Hami Basin, me"E-W blocking"is die manifestation of synsedimentary tectonic framework, while me "N-S zoning"is mainlythe result of compression and tectonic inversion in later stage. This further improves that die original Turpan-Hami Basin is extension-aL The basin inversion occurred caused by die compression in die later stage. The above mentioned characteristics may be die specialgeotectonic phenomena which only this kind of inversion basin has.
