In order to carry out a unified analysis and interpretation of the 2-D data from multiple profiles, constraints at the intersecting points of the profiles are taken into account, and solution of simultaneous equations with integrated data from all the profiles is accomplished by constructing a unified matrix of partial derivatives. The method is used to reprocess and reinterpret data from 6 wide-angle reflection/refraction Deep Seismic Sounding (DSS) profiles conducted in the Capital Area by the Research Center of Exploration Geophysics, China Seismological Bureau (CSB). As a result, a 3-D velocity structure and tectonic characteristics of the crust in this area are revealed. On this basis, and in the light of results by other geophysical techniques, the spatial scope of 4 crustal lowv elocity layers (bodies) and fault strikes are determined. |
