The epicentral distance in 30°~90° and the magnitude greater than 5.5 level, 261 earthquake events are selected to invert the deep structure of the Longmenshan Fault Zone and adjacent areas by the received function. Compared with the inversion results in 2007, the following conclusions can be arrived: 1) two profiles both show that the steep descent appears in the center of the Longmenshan nappe; and 2) to the south, the depth of the Moho tilts down 68 km, then rises, but to the north, the depth of the Moho tilts down 58 km, then rises. So this paper considers that on the eastern margin of the Songpan-Ganzi massif, the thickness of the crust shows that the south is thick and the north thin and the east is thick and the west thin.
