Abstract
The Landsat imagenary analysis of the calcareous High atlas (Morocco) leads to the reconstitution of the megafracture network which has controlled, for example, the progressive etting of a platform magmatism (from olivine-gabbros to plagioclasites and nephelinic/ pseudo-lencitic rocks) with its NiCu, FeTi and rare earth mineralisations.This network is made up of two conjugate systems (NNE-SSW and E-W) which limit rhomboidal blocks and whose last major tectonic activity spread from Upper Jurassic to Eocene times.This scheme of rhomboidal blocks, observed in the sedimentary cover, is interpreted here as reflecting the main structural pattern of the calcareous High Atlas basement.
