Abstract:

The evolutions of Quaternary drainage pattern in the Northeast China Plain are discussed in the paper. According to analytical results of core samples, we found that during Paleogene and Neogene periods there was a large paleolake in Dalianhe-Xiangshun region that deposited more than 700 m of lacustrine-aluvial coal-bearing fragmental rocks, and proved that the upper Songhua River and the Mudan River flowed into the large paleolake at that time. Because of the rising of Yitong-Yilan rift, the lower Songhua River eroded headwards and captured upper Songhua River and Mudan River; for this reason, we believe, that the Songhua River and Mudan River had never been able to flow westwards to the Songnen Plain. The capture river systems of the Songhua River and Heilong River were formed between the end of Pliocene and beginning of the Early Pleistocene. After that period, another large paleolake was formed in the western Northeast China Plain during the Early and Middle Pleistocene, thus the surrounding rivers to flow into the paleolake to form a centripetal drainage.

Key words: capture river system, centripetal water system, paleodrainage pattern, Northeast China Plain and its neighboring regions
