摘要(Abstract)：

鄂尔多斯盆地南缘晚三叠世的湖盆充填与秦岭造山关系密切,秦岭造山对延长组沉积研究十分重要.结合露头与岩心、沉积与物源区资料,分析晚三叠世秦岭造山与事件沉积的耦合性.结果表明:(1)物源区隆升,造山带前缘快速下沉,湖平面上升,南陡北缓的不对称盆地形成;盆地南缘快速堆积的三角洲前缘沉积在重力失稳条件下向造山带前缘滑塌形成浊积岩、砂质碎屑流,频繁的地震导致大量的砂岩脉形成.(2)盆地南缘火山喷发,一方面导致生物组合发生变化;另一方面由于凝灰岩富营养组份导致湖水中生物繁盛,并最终促成优质烃源岩的形成.该研究结果对寻找烃源岩、判断沉积相、分析构造背景,以及油气勘探具有一定指导意义.
