摘要
通过地震剖面反射结构分析,结合区域构造变形特征研究,认为天山南地区发育有压缩构造样式、扭动构造样式和复合构造样式等多种构造样式的构造。压缩构造样式主要包括背冲式和冲断式基底卷入型构造、叠瓦状双重构造和冲隆式盖层滑脱构造;扭动构造样式包括正花状、负花状和半花状构造;复合构造样式包括继承性挤压复合构造、挤压一扭张性复合构造和挤压一走滑复合构造。构造演化主要经历了塔里木克拉通形成、塔里木克拉通盆地形成和发展、前陆盆地形成和发展阶段等3个阶段。
The analysis of reflection configuration on seismic profile and the regional structural deformation characteristics indicate that there are many structure patterns in south Tianshan area,such as compressive structure pattern,shear structure pattern,and com- pound structure pattern,etc.The compressive structure mainly in- eludes base-involved structure(back thrust pattern and thrust pat- tern),imbricate duplex structure and cover-slipped structure.The shear structure includes positive-flower,negative-flower,and semi-flower shape structures.The complicated structure includes inherited extruding complicated structure,extruding-stretching complicated structure,and extruding-slipped complicated struc- ture.Structure evolution is divided into three phases,including the creation of Tarim carton,the creation and development of Tarim carton basin,and the creation and development of foreland basin.
