Abstract
Modelling of five profiles in the NE area of Madrid Basin shows that low anomalies are related to both the thicker sediments infill of the Basin and the basement rocks like gneiss and grani tes. The highs are related to thick sequences of alternating slates and quarzites, outcropping or underlaying a thin caver. The main gradients are related to the marginal faults of the Basin. The existence of a granitic body and a NE-SW striking fault, was also detected. Out of the data obtained in the models, an isobaths map has been depicted of Madrid Basin which shows a fault bounded structure.
