3.1. Meuse group (authors: Gullentops & Paulissen)

Description: This group unites all fluvial deposits in the Meuse basin, essentially of the River Meuse and its tributaries, mostly draining the Ardennes. These sediments, from the highest terraces to the actual alluvial plain, are divided into formations according to the evolution of the drainage in the basin, which is reflected in the lithological constitution. All names and type localities are chosen from a small area to assure the correct vertical succession of the terraces. Each formation comprises several terrace levels of lower rank. The first two Formations belong to the Mio-Pliocene and are described here for completeness.
