| Abstract: | Teleseismic body wave traveltime tomography is used to inverse the three-dimensional seismic velocity structure beneath Shizigou in the western Qaidam basin.The travel time are picked from the continuous observation data on a small seismic array of stations deployed during 2004-2007.The tomographic results obtained indicate that a NW-trending low velocity anomaly just beneath the target region insert northeastwards with a high dip angle.In the north, northeast and east of the low velocity anomaly, some high... |
