Applied research of Rayleigh wave sounding method in uranium resources exploration in Wulanchabu depression of Erlian Basin

According to the characteristics of shallow bury depth of uranium resources, and small difference of wave impedence between surrounding rock and ore-bearing target layer in Wulanchabu depression of Erlian Basin, this paper discusses the possibility of the Rayleigh wave sounding method for shallow strata detecting. Study shows that Rayleigh wave sounding method can get the horizon information of target layer, which can make up the shortage of the reflection wave seismic sounding application, and also has positive guiding significance for shallow strata sedimentary positioning and regional geological prospecting work.
