| Abstract: | This paper is based on the artificial source of shallow seismic acquisition method for detecting the active faults buried within Lhasa inter-mountain basin. The key technical problems are discussed for seismic profiling of buried faults in this geological condition. The choice of seismic instruments, scheme design, parameter selection, data processing, data interpretation and the method of fault recognition are put forward. The main parameters such as strike, dip direction, upper break-point and so on were ascertain in Niangre fracture, Nalinlaka fracture, Lhasa fracture and Duodi fracture, providing the first information for active fault research in Lhasa area. |
