VELOCITY STRUCTURE OF THE CRUST IN EASTERN QINLING MOUNTAIN

A seismic sounding profile crossing the eastern Qinling Mountain was performed in the Western Henan Province, China. The data are interpreted with 2-D model in this paper. Our results show that the crustal structure are composed of several layers. The upper crust has variation of velocity from 4.0hm/s to 5. 5km/s. A LVZ occurs in the middle crust,and a little change of velocity (6. 5～6. 9km/s) exists in the lower crust. Three deep faults cutting the Moho discontinuity are also exhibited. These features reflect the thrusting reconstruction of tectonics of this area.
