Abstract

The Madrid basin (Central Spain), is over 20.000 km2 in size. Its evolution was conditioned by basement uplifts (Central System and Toledo Mountains) during the Alpine orogeny. The Madrid basin is connected with the Loranca basin to the NE corner and with La Mancha basin to the S. It displays a continuous succession, accumulated from Late Cretaceous to the Late Miocene, of up to about 3.000 m thick at Pradillo well. Nevertheless, seismic permit to interpretet that, a depocenter close to Central System South Thrust. In this study four different methodologies were used, “Euler Deconvolution”, “Source Parameter Imaging”, “Analytic Signal” and “Tilt Depth, in order to obtain depth to basement estimations from aermagnetic data. These methods work for simple source geometries, estimating depths as a good starting point for a structural interpretation. In the Madrid Basin, this knowledge is important due to the geothermal and hydrological potential of the basin, as well as for CO2 storage.
