| 摘 要： | 通过区域地球物理场多重信息的综合研究 ,可将东北东部地球物理及地质块体划分为A、B、C三类。它们在空间上有序的分布 ,特征上各自相异。揭示出所共处的区域岩石圈的大地构造环境演化历史的全过程。B类地块代表了太古宙陆块的形成 ;C类地块反映了古亚洲构造域复杂的造山过程 ;A类地块则揭示出中生代以来壳幔作用动态过程—拆层作用和盆山构造的形成及对前期构造的强烈改造

| Abstract: | Through the comprehensive study to the multiple information of the regional geologic physical field The geophysics and geological masses of eastern part of the Northeast can be divided into three classifications (A,B and C) In space,showing a regular distribution;in characteristics,showing various differences That revealed the whole evolutionary process of the geotectonic environment of the regional lithosphere The"B"mass indicated the forming of the Archeozoic landmass The"C"mass only indicated a complex orogenic process of the Paleo-Asiatictectonic domain The"A"mass revealed a post-Mesozoic dynamic process of the crust-mantle action-the decoupling process tectonism of the forming of basin-range structure,and the intense transformation of previous tectonism |
