Die Antiklinale von Wavreille

With your back towards the old lime kiln, take a moment to admire the Wavreille anticline. It is mentioned in almost every Belgian geography manual and is classified as a listed site. An anticline is a dome-shaped fold that appears in the landscape as a hill levelled out by erosion. The layers were formed by layer upon layer of sea-sediments accumulating during millions of years. The thus formed layers appear at the surface in longitudinal strips that are symmetrical in relation to the axe of the crease. The sheer weight of the superimposed strips ends up turning into stone the sediments contained in the calcium carbonate that makes up at least 50% of limestone. The ceaseless movements of the earth's crust and the incessant overlaps and creases created by the continental drift (2 to 15cm per annum) end up creating anticlines.
