摘要:

根据地震剖面解释成果,分析了塔里木盆地塔中低凸起内部主要构造变形特征。塔中地区构造变形以层内滑脱和基底卷入并存,伸展、逆冲、反转与走滑相伴生为主要特征,主要构造样式可分为挤压构造、走滑构造、拉张构造、反转构造和塑性流动构造等5大类,进一步可细分为多个亚类。受早期构造背景和区域动力学机制变化影响,塔中地区不同构造样式分布具有一定规律性,NW向和NE向断裂分别具有挤压逆冲和走滑性质,拉张构造发育在深部中、下寒武统和浅部三叠系内,而反转构造主要发育在深部寒武系和奥陶系内。

关键词: 构造样式, 挤压, 走滑, 伸展, 塔中低凸起

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
