Due to the multi - period tectonic movement and evolution of mechanical mechanism , syndeposition structures occur extensively in jiyang sag , the base of the sag subsided alternatively during the fault depression , which resulted in sinking of top bending and complicated block structure accordingly , reconstructed the syndeposition intensively , and produced the special structural landscape in combination with all levels of faults and sedimentary formations within it 摘要济阳坳陷由于受到多期构造运动的影响,在前第三系古地形高点背景上广泛发育同沉积背斜构造,然而由于坳陷在断陷期基底滚动式沉降,造成挠曲顶部的塌陷,形成复杂的块断结构,使本区同沉积构造发生强烈改造,往往与各次级断层或沉积地层相复合,表现出独特的构造景观。
The study results on hydrocarbon preserving conditions have suggest ed that influenced by latter tectonic movements , especially by the yanshan ~ himalayan tectonic movement , obviously different hydrocarbon preserving conditions occur between the eastern and the western parts bounded by the qiyue mountain . the whole lower paleozoic hydrocarbon enclosing and preserving conditions for the shizhu synclinorium - fangdoushan antici inorium to the west of qiyueshan mountain have the advantage over those of the qiyueshan antici inorium - lichuan synclinorium to the east of qiyue mountain 通过油气保存条件的研究认为:受后期构造运动的影响,尤其是燕山期?喜山期构造运动的影响,造成区内以齐岳山为界东西油气保存条件存在明显差异,齐岳山以西的石柱复向斜?方斗山复背斜下古生界油气整体封存条件明显优于齐岳山以东的齐岳山复背斜?利川复向斜。
Therefore the flexural stress covers a large percentage of the total stress field . the study of the flexural stress field of the continental lithoshpere in western china will contribute a lot to the understanding of the tectonic evolution of continental lithosphere and the global plate tectonics 研究中国西部大陆岩石圈的挠曲应力场对于了解该区总应力场的性质、研究板内造山运动和青藏高原隆升以及地球动力学都具有非常重要的意义,有助于理解构造运动的动力机制和大陆岩石圈的运动特征。
There existed several strong reformation of late - yanshan movement and himalaya movement the generation , development , disappearance and reformation are tightly related to tarim block , tianshan belt and tethyan tectonic zone , especially tianshan belt , which makes the great difference between present and original basin 该盆地形成后经历了燕山晚期和喜山期构造运动的多期强烈改造;其产生、发展和消亡以及改造与塔里木地块、天山构造带、特提斯构造域的演化息息相关。其中尤以天山构造带的活动影响最大,从而造就盆地今古面貌差异巨大。
Many times structure movements of huanhua basin result in many times water progradation and retrogradation . cycle sediment in portrait and stratum lapout & denudation in plane and vary of different types sand body are resulted in sediment process . it provides better condition for subtle trap 研究表明,黄骅坳陷构造运动的多期性形成多次水进水退,在沉积上产生了纵向的多旋回性和平面上的地层超覆与剥蚀以及不同类型砂体的变化,为隐蔽油气藏的形成提供了良好条件,盆地中区是隐蔽油气藏较为集中的分布区。
