Through synthetic seismogram we can use geological horizon calibrate the seismic profile, and establish the corresponding relationship between seismic data and geological data.

First reflection waveform characteristic parameters that exhibit lithologic variation are determined by defining geological characters of seismic horizon with the aid of waveform analysis.

An intensive geological survey and study on the lateral section prove that the the Tangshang Formation in different basins of eastern Zhejiang is not of the same horizon.
