Abstract:ABSTRACT. This paper presents the estimates of effective elastic thickness (T e) from free-air anomalies/geoid undulations and topography data in the southern São Francisco Craton, by using admittance function technique. The gravity field elements have been calculated from geopotential model GGM02C (GRACE mission).The observed admittance was computed by dividing the cross-spectra of the free-air anomalies/geoid undulations by the power of topography. Theoretical admittances were estimated based on two hypothes… Show more
