Deux régions naturelles, géologiquement distinctes, caractérisent le Luxembourg. Les différences lithologiques et structurelles du sous-sol impliquent des paysages géomorphologiquement différents. Des types de végétations distincts s'y sont établis, les modes d'agriculture et les développements économiques sont différents, et ce dès le début de l'occupation de nos régions par l'homme.
The Grand-Duchy of Luxembourg shows on its small area of 2586 km2 a surprising geological diversity. It is divided into two major natural regions, which are geologically and geomorphologically different, the differences being the result of Late Tertiary differential uplift movements inducing erosional processes that uncovered the major unconformity zone between the Devonian and the Triassic rocks as seen today. The northern region, covering about a third of the surface of Luxembourg, is called ‘Eisleck' and belongs to the Ardennes - Rhenish Shield region, a part of the Hercynian mountain belt that extends through France, Belgium and Germany.
