【摘要】 根据地震资料、钻井和野外调查等研究,认为天井山构造带广泛发育重力滑动构造、断层转折褶皱、倒转背斜和双重构造等构造样式.天井山构造带变形具有垂向分层特点:上部构造主要为断层转折褶皱,02tjs10测线附近变形强度最大,向两端变形逐步减弱;下部构造为多个逆冲岩片叠置所构成的双重构造.通过构造物理模拟实验,证实天井山构造带在北西—南东向挤压应力作用下变形序列为前展式逆冲叠瓦式构造组合;天井山构造带存在多个滑脱层系,才会形成分层变形、垂向叠置的不协调收缩构造变形.该研究可以为天井山构造带乃至龙门山油气勘探提供指导.更多还原

【Abstract】 According to the comprehensive study of the earthquake and field surveys,Tianjing mountain Tectonic zone has wide range of developmental of structural styles such as gravitational gliding tectonics,fault-bend fold,overturned anticline and dual structure.The deformation characteristics of Tianjing mountain Tectonic zone is vertical stratification.By the construct physical simulation experiments,proving that the Tianjing mountain tectonic zone thin-skinned structure which developed in Indosinian is controlled by south-north compressive stress and northwest-southeast gravity gliding.In the Himalayan period,the deformation sequence of Tianjing mountain tectonic zone is piggy-back thrust imbricate structure combination controlled by south-north compressive stress.The Tianjing mountain tectonic zone has more than one detachment systems.In the decollement,there are hierarchical deformation and vertical stacking of uncoordinated contraction of tectonic deformation formed.更多还原
