f Gravity Modelling - a Contribution to the Knowledge of Madrid Basin Structure (Spain)

The Bouguer anomaly pattern reflects the density variations of the crust due to the different forming rocks and geometry. Gravity procedures make possible to model the structure of the crust. In these procedures several limitations must be taken into account to start with, of geological nature ( geological mapping, structural data, boreholes,.. ) and geophysical nature as well (seismic, magnetic, ...) that would provide enough information and would reduce the degree of unaccuracy of the final model.
