摘要
利用地质和人工地震测深剖面资料 ,研究了青藏高原东北缘的地质构造背景、地壳结构和莫霍面形态 .主要结果是 :1给出了青藏高原东北缘的大地构造分区和主要深大断裂的特征 ;2主要利用人工地震测深资料得到莫霍面的基本特征 ;3地表断裂与莫霍面的某些特征有较好的对应关系 。
WT5BZ]The geological structure background, the crustal structure and the Moho shape in the northeastern margin of the Qinghai Tibetan plateau are studied in this paper based on artificial seismic sounding profile as well as geological data. The main results are summarized as follows: ① The geotectonic subdivisions and the characteristics of main deep and large faults in the northeastern margin of the Qinghai Tibetan plateau are presented; ② The general features of the Moho are obtained mainly based on artificial seismic sounding data; ② The surface faults have good relation with some features of the Moho, which suggests that such complex crustal structure might be the preparation environment of strong earthquakes.
