【摘要】 本文利用地震测深资料得到的地壳波速结构,结合岩石学研究成果,建立该地区地壳结构的岩石(学)地球物理模型,并由此讨论该地区深部地壳结构的构造地质意义。指出,华南东部地区主要具由扬子古陆块与华夏古陆块相互作用引起的叠壳式陆内层块构造活动特征,且伴有异地块(?)增生于华夏古陆边缘更多还原

【Abstract】 By using the structure of crustal wave-velocity whichinferred from seismic sounding data and by referring to the petrographic research achievements, a petrographic-geophysical model of the crustal structure is set up and the tectonic significance of deep crustal structure is also discussed in this paper. The authors point out that there are superimposed intercontinental layer-blocked structures in the area between Yangtze Old Land and Cathaysia as well as the accretion of allochtonic block along the boundary of Cathaysis in South China.更多还原
