摘要：

松辽盆地上侏罗一下白垩统,可划分出两个地震超层序和四个地震层序.根据地震反射的内部结构、几何形态,划分出水下扇与扇三角洲、湖泊、河流、浊积扇和火山岩及火山碎屑岩等5类沉积体.

Abstract:

Songliao Basin is composed mainly of Upper Jurassic-Lower Cretaceous sediments and could be divided into four seismic sequences and two supersequences.According to the texture and geometry of the basin's seismic reflectance,sedimentary bodies such as subaqueous fan,fan delta,lacustrine,fluvial,turbidite fan,volcanic rocks and volcaniclastic rocks have been recognized.
