| Abstract: | The S wave data are selected from the records of 1 946 earthquakes observed in the period from 1984 to 1993 by seismic network in the zone of 104～112°E, 31.5～38°N in Shaanxi, Shanxi, Henan, Hubei, Gansu and Ningxia Provinces.The S wave velocity image of the crust beneath the Weihe downfaulted basin and adjacent areas is obtained by means of seismic tomographic technique. The results show that the non uniform S wave velocity structure of deep crust is closely related to the difference of geotectonic ele |
