SEISMIC CHANGING WAVE METHOD TO PROSPECT CRUST AND UPPER MANTLE STRUCTURE IN HAICHENG SEISMIC AREA

Zhno Guomin ( Seismological Brigade of Liaoning Province ) Liu Zhirong; Li Aimin ( Liaoning Seismological Bureatu )  
In order to study the prospecting effect of seismic changing wave method, and to increase the informations on deep cnust and upper mantle structure in Haicheng seismic area, two sounding profile of changing wave weve arranged along DSS profik in this region. The interpretation of data show that the deep crust structure is layer in Haicheng seismic area the Moho depth is shallow in the south(32-33km) and deep in the north(36~38kin). The prospecting effects in some important geological structures, such as the location of upper mantle upwarp and its depth, deep and large faults in prospecting area, are consistent with DSS method. Meanwhile, some informations on upper mantle structure. have been obtained.
