Abstract

To deal with magnetic modelling, remanent magnetization as well as susceptibility of the rocks that generate an induced magnetic field by the interaction with the Earth Magnetic field has to be addressed. In presence of primary and/or secon- dary fields, it is essential to consider the total magnetization as the sum of induced and remanent components, so that modelling integrates the effect of the intensity, inclination and, to a lesser extent, declination of the total magnetization generated by the source bodies. In this context, magnetic properties and density have been measured in drilled samples, with the aim to model and fit magnetic and gravimetric anomalies of the Central High Atlas Range, in the following units: paleozoic sediments, CAMP basalts, jurassic limestones and gabbros, trissic redbeds, cretacic limestones and cenozoic rocks. The contrasted petrophysical properties between units, whose geometry is constrained by means of field data (map- ping and dipping), allow us to refine the cross sections and suggest possible variations in the thickness and/or configura- tion of the anomaly source bodies.
