【摘要】 概述了青海门源─福建宁德地学断面的综合地球物理研究结果．综合研究以贯穿断面的深地震测深剖面资料为基础．综合地球物理模型表明了各大地构造单元的结构特征及相互关系．断面显示了太平洋板块、印度板块与欧亚板块之间相互作用的结果．断面西段由于印度板块与欧亚板块碰撞，急剧的岩石圈缩短使地壳增厚；断面东段则处于西太平洋裂陷引张状态，形成一系列张性断裂和断陷盆地，导致岩石圈变薄，地壳亦随之减薄．本文还讨论了断面中几个重要构造单元的动力学问题．更多还原

【Abstract】 This paper outlines the geophysical results on the Geoscience transect from Menyuan of Qinghal Province to Ningde of Fujian Province. The study i based on the data of deep seismic sounding(DSS)profiles on the transect.The comprehensive geophysical model shows the features of each tectonic units and their interrela tion.The transect maps reflect the results of interaction between Pacific Ocean plate, Indian plate and Eurasia plate.On the west section of the transect, the crust is thicken by rapid shorten of lithosphere due to the collision of Indian plate and Eurasia plate,and on the east section,the rifting and extension of the western Pacific Ocean has generated a series of extensional faults and rifted basins,produced thinned lithosphere,and crust also has thinned.In addition,this paper discusses the geodynamics of several significant tectonic units on the transect.更多还原
