Sedimentary environments and controlling factors of Permian source rocks in northeastern Sichuan Basin:A case study of Muguakou profile in Chengkou

  • 摘要: 基于前人研究资料和野外露头剖面详细观测及样品实测数据,以川东北城口木瓜口二叠系剖面为例,通过常量元素(氧化物)、微量元素等参数进行古环境条件恢复,分析了古环境与烃源岩发育的相关性,并探讨了烃源岩纵横向分布的主控因素。研究认为:(1)在横向上,研究区二叠系深水陆棚相、台盆相烃源岩最发育,有机质丰度也相对高,台内洼地亚相烃源岩丰度较低;(2)在纵向上,二叠系烃源岩主要发育于海侵半旋回中,最大海泛时期烃源岩有机质丰度指标最好;(3)古生物生产力和有机质保存是控制烃源岩有机质丰度的主要因素,并且只有当古生产力高,有机质保存好时,源岩的有机质丰度最好,两者缺一不可。
