文摘
- •
Anti-Atlas and Ougarta Variscan belts connect obliquely in the Tafilalt-Maider area.
- •
Fold interferences there occur in a thick-skinned tectonic regime.
- •
Fold trend is controlled both by basement faults and superposed stress events.
- •
Paleofault inversion and stress rotation account for a croissant-shaped anticline.
- •
Opening of barite veins postdates the Variscan folding.
