Abstract
Abstract: At Bou-Azzer El Graara area in the central Anti-Atlas and in the Lower Cambrian, the ‘Calcaires inférieurs’ formation (basal conglomerates and limestones unit), together with volcanism and the Tikirt sandstones, constitute the first sedimentary cycle; evidence of the dislocation and the crustal extension on the Paleo-Gondwana. The palaeogeographic evolution of this area takes place in global geodynamic evolution, ending with the formation of Theic ocean.
