PRELIMINARY APPROACH TO GEOPHYSICS OF BASINS

The studies on tectonic history,subsidence and accumulation evolution of basins as well as the dynamic forces on basins with the application of geophysical data and information combined with geological information are the main subjects of the geophysic analysis of basins.Through various techniques of geophysical investigations,the lithospheric geophysical information and data could be obtained and the tectonic-geophysical models for basin origins could be proposed on the basis of man-machine combined interpretation(mathematical forward and inverse computation).Consequently,the geophysical background can be provided for the dynamic simulations quantitatively on various geological models of basins and the appraisal of oil/gas prospects in basins.
