松辽盆地是中国东部中、新生代发育起来的大型断、坳陷沉积盆地,以陆相含油著称于世。在它的演化历史中,曾经历过多次构造上升与下降运动,形成巨厚的多旋回沉积岩系。其中三角洲相十分发育。近十年来,许多人对不同历史时期形成的三角州进行过大量报导和描述。其中王衡鉴等人较系统地对松辽湖盆三角洲进行了论述和分类。本文所论及的是松辽盆地南部出现较多,形成于早白垩世的三角洲。尽管这些三角洲之间千差万别,但从沉积古地理背景出发,可将其分为三大类。本文的分类与裘亦南等人的陆相三角洲分类大致相同。
The Songliao Basin is a large-scale, Cenozoic sedimentary basin developed in the Meso-Cenozoic in eastern China and known for its continental oil-bearing. In its evolutionary history, it has undergone many structural ascent and descent movements to form giant polycyclic sedimentary rock series. One of the most developed delta. In the past decade, many people have made extensive reports and descriptions of the delta states formed in different historical periods. Among them, Wang Hengjian and others systematically discussed and classified the Songliao Lake basin delta. This article deals with the delta that formed in the early Cretaceous in southern Songliao Basin. Although these deltas differ widely, they can be divided into three broad categories based on the paleogeographic setting. The classification of this article is roughly the same as the continental delta of Qiu Yinao et al.
