主　　题：high-resolution refraction ray hit analysis A'nyemaqên suite zone basement structure 

摘      要：Based on the results obtained from Pg wavefront imaging in active source deep seismic sounding, we propose a new ray hit analysis method for high-resolution seismic refraction profile data processing. This method can be used to further determine possible refraction interface, especially spatial location of basement and its pattern characteristics in complex upper crustal structure region, making data processing for high-resolution refraction profiles more fine. We use this method to study the crystalline basement structure of east part of A＇nyemaqên suite zone at northeast side of Qinghai-Xizang Plateau and the basement patterns as well as its spreading features at the east part of Anemaqen suite zone and its adjacent region were determined.
