%X It is difficult to explore in high velocity basalt shield area. The methods of wide angle seismic technology are put forward to solve this problem, taking a distinguish area of our country as an example. At first, the condition under which the wide angle seismic signal exists and the problems which are faced on in application have been theoretically discussed. The kinetic characteristics of the wide angle seismic signal and the effect of the wide angle reflection for noise have been analyzed by the forward theoretical model. The phenomena of the correction stretch and the characteristics of the dynamics and the wave field have been discussed in this paper. The wide angle seismic data have been processed exactly and the sub basalt seismic imaging has been achieved based on these methods.
