Location: Aiguille du Belvédère summit, Aiguilles Rouges massif, Western Alps, France.
Description: This project is part of the PhD thesis of Antoine Mercier, that aims to understand the geometry and kinematics of the alpine deformations in the Mont-Blanc/Aiguilles Rouges area. Atop the Aiguilles Rouges massif, a remaining of the Mesozoic cover can be observed atop the basement. At the bottom of the series, the Triassic unconformity is characterized like at other locations in the massif by an undeformed sandstone layer. Above, the Triassic dolomites are affected by west-verging folds and are crosscut by a flat decollement, with above Liasic black shales being strongly shistosed and stretched.
