description: The volcanic succession from the Triassic basin of the Ksour Mountains is formed by three basaltic units, interlayered with silico-clastic to evaporitic sedimentary levels and overlain by Rhaetian-Hettangian limestones. These basalts are low-Ti continental tholeiites which show, from the bottom to the top, the same chemical evolution as the basalts from the Triassic basins in the Moroccan High Atlas. This volcanism represents the easternmost witness of the CAMP province associated with the central Atlantic rifting, at the Triassic- Jurassic boundary.
