Synergy between multispectral remote sensing and ground data for the design of a new geodynamic model of the Paleozoic basin opening of central Jebilet (Morocco)

The geodynamic model of the Palaeozoic basin opening of central Jebilet has been unknown before this study in spite of the abundance in the geological studies carried out in the studied sector using conventional methods. This is due to the scarcity of the key beds and synsedimentary structures. Using the synergy between the image data of the Landsat satellite TM sensor and the ground data, we have highlighted, herein, new structural data allowing the design of a new model of the Palaeozoic basin opening of central Jebilet. This opening could have been made according to dextral submeridian transverse faults with the individualization of subequatorial normal faults.Original Abstract: Le modele geodynamique d'ouverture du bassin paleozoique des Jebilet centrales est reste jusqu'a nos jours mal connu, malgre l'abondance des etudes geologiques qui ont ete faites par les methodes conventionnelles, a cause de la rarete des reperes lithostratigraphiques et des structures synsedimentaires. Grace a la synergie entre les donnees image du capteur TM du satellite Landsat et les donnees du terrain, nous avons mis en evidence de nouvelles donnees structurales, permettant de proposer un nouveau modele d'ouverture du bassin paleozoique des Jebilet centrales. Cette ouverture se serait faite selon des decrochements dextres submeridiens, avec l'individualisation de failles normales subequatoriales.
