| 摘 要： | 本文依据地震地层学原理,结合层速度和砂岩百分比的研究,描述了辽东湾南部下第三系地震相和沉积相类型及特征,确定出近岸水下扇沉积体系、三角洲—滑塌浊积扇沉积体系、滨浅湖—滩坝沉积体系和深湖—深水浊积扇沉积体系,指出这些沉积体系的平面分布具有不对称性,垂向演化具有继承性和新生性的特点。最后预测了有利勘探地区。

| Abstract: | This paper describes the types and characteristics of seismic facies and sedimentary facies of Eogene in southern Liaodong Bay on the basis of seismic stratigraphic principles and interval velocity and velocity spectrum. The authors have determined the following depositional systems, i. e. nearshore submerged fan, delta-slumping turbidite fan, shallow lake-beach/bar, and deep lake-deep water turbidite. Distribution of the depositional systems has asymmetry in plane and successional difference in vertical. Finally, favorable exploration area has been predicted. |
