| 摘 要： | 松辽盆地南部泉四段沉积体系具有特殊性。在前人工作基础上，对泉四段沉积厚度、砂体发育、气候条件、静水水体发育等沉积特征进行详细解剖，重新厘定泉四段沉积时期，气候干燥，总体为冲积扇—河流沉积体系，平面上发育有三大物源、6个水系，建立了松辽盆地南部泉四段沉积体系模式。并提出了“特殊环境使河流体系下游出现枝状河流域和河漫湖沉积，呈现多物源、多沉积中心沉积特征”的新观点。

| Abstract: | Sedimentary system of Quan-4 Member in south Songliao Basin is distinctive.Based on study by predecessors,this paper has carried out a detailed anatomy on sedimentary features of Quan-4 member such as sedimentary thickness,sand body development,climate conditions,and quiet water body development.It is recognized that sedimentary age of Quan-4 Member has a dry climate,overall as an alluvial fan-fluvial sedimentary system.Three big material sources and six water systems have developed on the plane,resulting in the sedimentary system pattern of Quan-4 Member in south Songliao Basin.A new point has been brought forward that specific environment has caused occurrence of branched fluvial domain and fluvial overflow lacustrine sedimentation,presenting features of multi-sources and multi deposit centers. |
