Short summary

The Aar and Mont Blanc regions in the Alps are large granitoid massifs characterized by high topography. We analyse when these granitoids were first exhumed to the surface. We test this by tracking specific garnet grains, which are exclusively found in the granitoid massifs, in the sediments contained in the alpine foreland basin. This research ties in with ongoing debates on the timing and mechanisms of mountain building.
