| 摘 要： | 借助高精度层序地层学、构造地层学、精细沉积体系分析和构造-古地貌恢复的理论和技术手段,对坳陷期松辽湖盆开展了整体性和综合性的再评价。研究认为,拗陷期影响和控制松辽盆地沉积过程的最主要因素是环古松辽湖盆发育的内环坡折带和外环坡折带。可划分为两大类型,即张扭性和压扭性。张扭型坡折以泉头组为代表,压扭型坡折在姚家组最典型。它们各自控制着不同的沉积过程。在此基础上,建立了具有典型代表意义的古松嫩平原沉积模型和古松嫩湖泊三角洲沉积模型。提出了以内、外环坡折为基础的有利勘探方向。

| Abstract: | The characteristics of slope break during depression stage in the Songliao basin of NE China are analyzed and indicate that double flexure slope breaks extend in a circle across the basin.One is nominated inner slope break,and the other is external slope break.Under different regional stress fields,the control of slope break on sedimentary process is different.Under the extensional stress field,the sedimentary system of meandering river is found in the inner slope break and the braided river sedimentary sys... |
