松辽盆地北部深部地壳结构及盆地成因机制

根据松深大部面地震反射结构及大地电磁测深资料，结合当前国际上对地壳结构的研究成果，将松辽盆地（北部）的地壳分为上，下2个部分。分析认为，上地壳上部呈现脆性，发育有近水平的韧性剪切带，由此认为松辽盆地主要是由拉张作用形成的。此次深部综合地质研究所获得的资料，是建立松辽盆地形成，演化模式的重要依据。

Crustal Structure beneath Northern Songliao Basin and Songliao Basin Genesis Mechanism

Based on seismic reflection structural characteristics interpreted from deep seismic profiling lines transversed the northern Songliao Basin and MT sounding data and on the conclusions drawn by other authors studying the crustal structure, it is thought that the crust for Songliao Basin can be divided into the upper and the lower part. From analysis,it is concluded that the upper part of the upper crust is brittle and the lower part is tenacity and deformed with the development of a shear zone. Therefore, it is concluded that the basin was formed by stretching. The results from the deep integrated geologic study played a very important role in establishing Songliao Basin evolution.
