层序地层控制下的滩相发育演化规律 -以城口-鄂西地区飞仙关组为例
飞仙关组,鲕粒滩,层序,海槽
Draft Pending
基于野外露头剖面、岩石薄片、测井、录井、地震等资料，分析了城口鄂西地区飞仙关组滩相沉积特征及演化规律。笔者在前人研究基础上建立了飞仙关组层序地层格架，由下至上将飞仙关组分为两个三级层序，五个四级层序（即Ⅰ、Ⅱ、Ⅲ、Ⅳ、Ⅴ层序），下部三级层序分为两个四级层序，上部三级层序分为三个四级层序。在层序地层学的基础上分析研究区滩相发育及其演化过程。研究区飞仙关时期具有西南高东北低，东陡西缓的古地貌特征，西侧鲕粒滩主要发育在层序Ⅳ海侵体系域中，至中部鲕粒滩发育层位上升至层序Ⅳ中的高位及层序Ⅴ的海侵体系域中，而到了东侧鲕粒滩全部发育在层序Ⅴ的高位体系域中。台地边缘滩表现出随海槽边界的退缩不断向海槽方向不断迁移，且发育的层位不断抬升的特征，且不同体系域鲕粒滩表现出不同特征。平面上台缘鲕粒滩主要沿着古地貌和海槽的迁移而不断迁移变化。古地貌高度和海槽两个因素共同影响滩相的发育和演化
