【摘要】 在前人研究成果基础上,对龙门山冲断带差异构造变形特征,构造几何样式,构造演化等几个方面进行了综述。研究表明,龙门山冲断带具有明显差异构造变形特征,即东西分带、南北分段、上下分层,同时发育大量构造变形样式,如断层相关褶皱、三角带、飞来峰、双重构造等等,在经历了多期复杂构造演化之后,构造变形样式具有多期叠加特征,最后提出详细地表构造地质建模、地震剖面精细解释及合理模型的建立,同时结合多种量化测试分析手段能够有效推进龙门山冲断带复杂构造样式与多期构造演化阶段分析研究工作,以及推动该地区的油气勘探。更多还原

【Abstract】 Reviewing the achievements in the Longmen Mountain thrust belt, especially the differential structural deformation, the geometrical styles of deformation and structural evolution. Typically differential structural deformation in the Longmen Mountain includes the zonation from west to east, segmentation from north to south, delamination from down to up, and lots of styles of deformation developed in the Longmen Mountain thrust belt, such as fault related folds, triangle belt, klippes, duplex and so on. meanwhile, it has experienced multiphase of structural evolution with the result of superimposed character. At last, it is put forward that the geological model based on the surface, the seismic sections elaborated explained, the reasonable geological model and several quantizing methods all may impulse the study of the complicated structural styles, the characters of its evolution and the hydrocarbon exploration activity in the studied area.更多还原
