摘　　要：陵北地区浅层玄武岩十分发育,常规纵波地震勘探因透射能量弱,难以取得较好的资料。这里提出应用广角转换波地震勘探方法来进行探测,理论分析和实际资料的采集、处理都充分说明,在浅层里存在高速层的地区,广角转换波勘探方法是行之有效的。In the north jiangling, the acquisition of qualitative P-wave seismic data is very difficult because of feebleness of the wave energy duo to the developed basalt in the shallow strata. This paper presents the wide angle seismic prospecting method. Both the theory analysis of data acquisition and processing of show that the wide angle seismic prospecting is effective in the region with high-velocity strata in the shallow.
