Internal Structural Deformation of the Tazhong Lower Uplift, Tarim Basin

Abstract

Abstract:

Based on the interpretation of seismic profiles, the internal structural deformation of the Tazhong lower uplift were analyzed. The structural deformation in the study area was featured by the combined distortion of detachment and basementinvolved, as well as extension, thrusting, inversion and strike slipping. In the Tazhong lower uplift, the structural styles could be divided into five types, including compressional, strike slipping, extensional, inversion and plastic structures, and more subtypes could also be identified. Influenced by the early geological backgrounds and various kinematic mechanisms, the distribution features of the structures in the Tazhong area are different. The NWand NEstriking faults are thrust and strike slip faults, respectively. The extensional structures are mostly stituted in the Triassic, and the inversion structures are distributed in the Cambrian and Ordovician.

Key words: structural style, compression, strike slipping, extension, Tazhong lower uplift
