4 ) analyses boundary faults of the cenozoic longmenshan foreland basin , and thinks the basin boundary faults , being active fault , are thrust and dextral strike - slip . so the longmenshan foreland basin is dextral strike - slip foreland basin 4 )通过对新生代龙门山前陆盆地边界断裂的考察分析，认为盆地边界断裂具逆冲推覆及右旋走滑作用特点，为活动断裂。
At the same time , i discussed the tectonic - sedimentary configuration , sedimentation and sequence evolutive character of the northeast sichuan foreland basin in the xujiahe age , late trias . in conclution , i drawed the following conclusions 在此基础上，深入讨论和论证了川东北前陆盆地晚三叠世须家河期沉积盆地的构造?沉积格局，以及沉积、层序演化特征。
Based on the theories of petroleum system and reservoir geochemistry , the kuche foreland basin is selected to study some geochemistry problems on the process of petroleum from source to trap in this work 以含油气系统和油藏地球化学的理论、方法为指导思想，选择塔里木库车前陆盆地为研究对象，重点进行了烃源岩生物标志物组成特征的剖析和典型油气藏形成机理的地球化学研究。
Available knotty problem about exploration situation require petroleum resources theory , technology , operating position manipulation , together with carefully research about source rocks characteristics , foreland basin evolutionary 这些问题需要紧密结合前陆盆地构造发育和含煤地层沉积的特点，研究烃源岩分布差异性特征，从煤系烃源岩、天然气成藏理论和勘探技术等方面加以解决。
The present longmenshan foreland basin lies between the longmenshan thrust belt and the longquanshan fault . the dayi conglomerate at the bottom of the chengdu basin , although people of the past having studied a certain degree , hasn " t same sugest 大邑砾岩的地质时限为上新世-早更新世，时代界定在4 . 6ma - 0 . 82ma之间，显示该区第三纪与第四纪之间是连续沉积的，其间不存在构造事件。
