Inversion tectonics, interference pattern and extensional fault-related folding in the Eastern Anti-Atlas, Morocco

In: Swiss Journal of Geosciences, 2008, vol. 101, no. 2, p. 397-408

The Anti-Atlas belt of Morocco is a Variscan chain which appears as a huge anticlinorium oriented NE-SW. In the internal part of this structure, the actual relief shows the basement cropping out as inliers (Piqué 2001) or boutonnières. The cover, a thick pile of Paleozoic sediments up to 12 km thick, is gently folded and of low grade metamorphism in its lower level. The lack of major...

Géologie structurale de l'Anti-Atlas oriental, Maroc

Robert-Charrue, Charles ; Föllmi, Karl (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2006 ; 1889.

Le Sud marocain constitue, par ses conditions désertiques, un terrain propice aux études géologiques. Toutefois les études publiées sur la déformation de l’Anti-Atlas oriental sont rares. Cette chaîne fait partie de l’orogène varisque (~300 Ma) qui s’est formé à la suite de la collision d’anciens continents nommés Gondwana et Laurussia pour former le super-continent Pangée....

Tectonics of the Anti-Atlas of Morocco

Burkhard, Martin ; Caritg, Séverine ; Helg, Urs ; Robert-Charrue, Charles ; Soulaimani, Abderrahmane

In: Comptes Rendus Geosciences, 2006, vol. 338, p. 11-24

The Anti-Atlas is reviewed and examined in the light of its geodynamic significance as a Palaeozoic basin and fold belt. Shortening is accommodated by polyharmonic buckle folding of the cover in a thick-skinned fashion without the development of any significant thrust/duplex systems. The Anti-Atlas is heavily inverted deep intracratonic basin, rather than a former passive margin of the...

Folding and inversion tectonics in the Anti-Atlas of Morocco

Helg, Urs ; Burkhard, Martin ; Caritg, Séverine ; Robert-Charrue, Charles

In: Tectonics, 2004, vol. 23, p. 1-19

The late Variscan Anti-Atlas of Morocco shows some conspicuous deviations from the standard anatomy of foreland fold-and-thrust belts. Large basement inliers crop out at a very short distance of less than 50 km behind the southeastern front of the fold belt, reminiscent of Windriver-style basement uplifts. In contrast to the Rocky Mountain foreland, however, the Anti-Atlas basement uplifts...
