Abstract

The thickness of the crust and its seismic velocity ratio Vp/Vs below the KHAV and SERG seismic stations installed in Dornod Mongolia were determined by the teleseismic receiver function H-k stacking inversion. The crustal thickness under the KHAV station was determined to be 33.1 ± 0.9 km, the seismic velocity ratio Vp/Vs was 1.82 ± 0.04, and the Poisson's ratio was 0.283 ± 0.014. The crustal thickness under the SERG station was determined to be 35.2 ± 0.6 km, the seismic velocity ratio Vp/Vs was 1.75 ± 0.02, and the Poisson's ratio was 0.257 ± 0.007.
