    Abstract:

    Deep seismic sounding (DSS) played crucial role in the crustal and mantle velocity structure detection, crustal deformation analysis and dynamics research of plateau uplift and craton destruction. However, the deep dynamic research with DSS data is still limited at the results description stage. For this reason, this paper summarizes the continental dynamic research methods based on the deep seismic sounding data. Results show significant and dramatic application of DSS data in the dynamic research. Wide angle reflection and refraction seismic phases are notable respond to dynamic process and lay the foundation of dynamic research. Crustal velocity contrast and analysis is important to verify the tectonic units and its evolution. Crustal factors, including thickness, Poisson’s ratio, velocity, especially the abnormal velocity zones, can provide insight to the crustal growth and deformation. Moreover, the phenomenon of S- wave split and Pn velocity versus azimuth are identified as seismic anisotropy indication and provide independent evidence for the dynamic research. With modern structure analytical methods, crustal structures models can be divided into three types of crustal- dynamical styles, and then the lithosphere evolution could be inferred from deconstruction of the models. Furthermore, DSS data provide constraints on the reconstructing petrologic composition modeland supply key factors of temperature and rheological properties for the dynamic simulation. This paper is essential to excavate the potential value of DSS data in dynamic research, as well as to link the DSS a close association with other geosciences disciplines.
