- Abstract:
- Through introducing the moveout correction technique in exploration seismology, we obtained a method to compute the receiver function beneath a station by stacking receiver function after normal moveout correction. We used the method to determine the SV-component receiver functions from 3-component broad-band digital recordings which were recorded by the Baoshan, Wanding, Cangyuan, Tengchong stations. The results show that, at the Baoshan, Wanding, Cangyuan stations, the depth of discontinuity is 700 km and it is deeper than the average of 660 km over the globe, meanwhile, there may be existed several discontinuities between 290 km and 500 km; however, the discontinuity beneath the Tengchong station is not clear at the depth of 700 km, and the depth of discontinuity in upper mantle is only 210 km, shallower than that beneath other 3 stations.
