Cross-sections through the Belgian Variscan Massif

Abstract

Two profiles through the Belgian Ardennes are described and depicted. The Cambrian to Silurian rocks, folded during the Caledonian orogeny, show a weak metamorphism. The cover, consisting of Devonian and Carboniferous, thickens towards the south and is thrown into a number of major folds during the Variscan orogeny. This was accompanied by a second stage of low-grade metamorphism.
