Genèse de systèmes karstiques dans la craie de la Basse Meuse (Frontière Belgo-Néerlandaise).
Different karst phenomena were intersected by underground and open-air quarries in Cretaceous chalks of the Belgian-Cutch border zone along the Meuse river. Dolines and more than one thousand solution pipes were observed. Solutions pipes can attain a depth of sixty metres. These may intersect endokarst features : sub-horizontal galleries developed along joints, round galleries without visible fissure and sponge networks. Occasionally, surfaces sculpted by cupolas and arched cavites stopping upwards were observed. At deeper levels, pluridecametric nodes of weathered chalk are developed under the base water level.
