Unraveling a distal segment of the West African Craton Paleozoic margin: Stratigraphy of the Mougueur inlier of the eastern High Atlas, Morocco

Because of its location in the boundary zone between the Anti-Atlas and the Atlas-Meseta crustal domains of Morocco, the Mougueur Paleozoic Massif is a key area to decipher the evolution of the Gondwana NW margin during the Paleozoic. In this work, we report for the first time the occurrence of Hirnantian sandstones, Silurian (Gorstian) graptolitic shales and probable Lower Devonian turbidites in the Massif. Comparison of our observations with regional stratigraphic data from literature allows us to suggest that the area was included in the distal part of the West African Craton passive margin during Cambrian-Devonian times.
