Utilização de Dados Gravimétricos Derivados de Altimetria Por Satélites e Geofísica Marinha no Estudo de Estruturas do Embasamento na Região da Bacia de Santos, Sp

Gravity data obtained from satellite altimetry can contain high frequency signals related to features that are not shown in the bathymetric models. This paper models the depth variations of the crust mantle interface (CMI) and the structures of the basement from gravity data inversion. The effect of the sedimentary cover is estimated from the thickness model available by NOAA and adapted to a model of sediment compaction. Bathymetric data of bathymetric Char General of The Oceans (GEBCO) and crustal thickness data obtained by seismic tomography are integrated in the inversion process, which includes the flexural isostatic model. This analysis results in the final inverted topography of the basement in the area of the Santos Basin, which coincides with the bathymetry only where there is no sediment cover and may reveal structures that are of interest for oil exploration.
