    摘要:

    三叠纪中期至侏罗纪早期的印支运动动力来源于华北板块与扬子板块的聚敛,聚敛作用形成巨大的NE-SW向挤压力首先导致济阳坳陷北西向压性构造的形成,产生了一系列NW向褶皱隆起带及其伴生的宽缓向斜,其次在对济阳盆地产生多处NW向挤压逆冲构造,伴之以褶皱构造。印支运动还造成本区地势起伏不平,剥蚀程度差异还导致相对隆起区与相对低洼区相间排列,上古生界保留较完整。

    Abstract:

    The Indosinian movement, beginning from the mid-Jurassic to the early Jurassic, is the product of the convergence of North China and South China plate, and imposing a far greater effect on the tectonic conditions in Jiyang depression through the immense NE-SW direction stress. Firstly, it leads to the formation and widespread of compressional structure with west-north direction, a process giving rise to NW oriented draping uplift belt and concomitantly wide and low angle syncline. Secondly, several NW oriented extrusion thrustings are caused latterly, which are mainly reverse thrust and the less abundant drape structures. Otherwise, the Indosinian movements results as well in the considerable relief in the study area, a phenomena, relatively uplifts aligned alternatively with the relative low-lying area, caused by the erosion difference. Finally, the upper Paleozoic is well preserved.
