Using both, the crustal magnetic lineations map of Mars published by the Mars Global Surveyor (MGS) MAG/ER experiment and the tectonic-structural features associated to the Tharsis uplift and mapped by ourselves, we have been able to generate a 2-D model of the crustal magnetization. Previous models assume uniformly magnetized strips whose dimensions are 200 km wide, 2000 km long and 30 km thick. A strip with these dimensions and with a magnetization of 20 A/m, would have a total magnetic moment of 2.4 X 1017 A-m2, that is agree with the 1500 nT measured by the MGS at 100 km high. If we assume different dips for the tectonic-structural features, then thickness of the magnetic strips changes according with the dip angles. These results imply that the magnetization volumes previously assumed would change if the thickness is modified. Topographic and gravimetric MOLA data have been used to determine crustal thickness of 20 km in the magnetic lineations area (Zuber et al., 2000), which could be useful to our model in order to modify the 30 km thickness initially suggested.
