The central Atlantic magmatic province in the Ksour basin (Saharan Atlas, Algeria).

Résumé

The volcanic succession from the Triassic basin of the Ksour Mountains is formed by three basaltic units, interlayered with siliciclastic to evaporitic sedimentary levels and overlain by Rhaetian–Hettangian limestones. These basalts are low-Ti continental tholeiites that show, from bottom to 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 central Atlantic magmatic province (CAMP) associated with the central Atlantic rifting, at the Triassic– Jurassic (Tr–J) boundary.
