Six motored augerholes (s1-6) have been carried out along a ~500-m-long N-S line across a surface sloping
gently southward (~1.7%) northeast of the village of Bilstain. There, sands and clays rest on the dolostones of the Dinantian 'Formation des
dolomies de la Vesdre' (s1-3, s5-6) or the limestones and shales of the upper Famennian 'Formation de Dolhain' (s4). They showed respectively:
(s1 and) s2 : 1.3 m brown weathering clay with angular dolostone debris, resting in situ on the fresh dolostone bedrock.
