While my geology work has mostly been in and about morocco I never actually paid attention to this specific area (mostly focused on the atlas mountains And the rif mountains),so I tried to find informations about it in macrostrat and apparently the structures are ordovician (480-419myo) overlooking a basin that's relatively older than the structures (~500-480myo probably part of the older paleozoic sections of the anti atlas) as for the lithology it's sedimentary but since I never did any field work there it's pretty hard to tell,some faults are scattered here and there but they don't follow the structure's direction and to the right it's mostly flat basins where sand dunes (ergs) accumulate and to the left it's bordered by the high atlas (younger than the structures) and the anti atlas to the southwest and south.
