Deep Structure of the Earth’s Crust Along the SVEKA Profile and its Extention to the North-East
A new integrated seismic and density model along the SVEKA profile in Finland is presented. The model has been obtained as a result of application of non-traditional approach to gravity data inversion that uses non-linear relationship between rock density, compressional and shear seismic wave veloci...

A new integrated seismic and density model along the SVEKA profile in Finland is presented. The model has been obtained as a result of application of non-traditional approach to gravity data inversion that uses non-linear relationship between rock density, compressional and shear seismic wave velocity. The distribution of P-wave velocity and S-wave velocity along the SVEKA profile was obtained due to re-interpretation of the original SVEKA’81 experiment data and new DSS data from the continuation of the SVEKA profile to the north-east. This seismic model and the new map of gravity field in Fennoscandia (1996) were used as a base for gravity modeling. The non-linear relationship between P-wave velocity, S-wave velocity and density was obtained as an inverse gravity problem solution and then used to calcu-late the density model along the SVEKA profile. Satisfactory fitting of observed and calculated model gravity field has been reached. It proves that using non-linear relationship between density, Vp and Vs for the purpose of gravity modeling can increase the quality of gravity inversion results. The new density model of the SVEKA profile explains the origin of some gravity field anomalies along the profile and reveals new details of the deep lithospheric structure of Fennoscandia. |
