【摘要】 为研究华北地台、西拉木伦加里东褶皱带及贺根山海西褶皱带交界地区的深部构造,在辽西-内蒙地区进行了转换波地震测深。本文给出了转换波测深的基本结果,同时试图通过对转换波方法本身的进一步研究,给出更多的关于地壳结构和间断面性质的信息,并据此进行测深结果的构造意义的讨论。更多还原

【Abstract】 To study the crustal structure of the boundary area of the north-China plateform and the Xar Moron Caledonian fold belt, teleseismic P-to-S converted wave prospecting was carried out in the region of western Liaoning and Inner-Mongolia. This paper reflects the results of the prospecting. Moreover, through systematic studies of the capability and limit of teleseismic P-to-S converted wave prospecting, more information about the reliability of the results, the structure of discontinuities such as Moho and the properties of the crust, as well as their tectonic implications, was obtained. The result shows that there is a distinct change in the properties of the crust between Linxi and Xar Moron river, which is near the newly determined geological boundary of the north-China plateform and the Xar Moron Caledonian fold belt.更多还原
