We determined high-resolution 3-D P-wave velocity and anisotropic structures under the Helan-Liupan-Ordoss western margin (H-L-O)structural belt and its adjacent region using 13,506 P-wave high-quality arrival times from 2,666 regional earthquakes recorded by 87 seismic stations distributed in Northwestern China during 1980 to 2008.The results show that the prominent low-Vp anomalies widely exist in the lower crust beneath the study region and extend to the uppermost mantle in local area,which indicate that the lower crust contains relative high-temperature materials and/orfluids(Zhao,D.P.,et al.,2010).
