THE LAYERED STRUCTURE OF THE CURST AND MANTLE MEDIUM IN CENTRAL INNER MONGGOLIA

The layered structure model of crust and mantle in the various station regions have been obtained by the way of fitting synthetic seismograms with waveform of deep focus telcseismic record of the six stations in central Inner Monggolia.The results have shown that the medium model of jining station region is similar to that of the northwest baundary of North China plain,whoes crustal thickness is about 46 km, The crustal thickness under ihe regions of Bailingmiao, Walanhua, HuhehaOte, Helingeer and Qingshuihe five stations are about 54 km,with alternate high velocity layer and low velocity layer,which is similar to the struetture in the northwest and the southwest areas of our country.
