Een tijdelijke ontsluiting van het Zand van Kiel (Formatie van Berchem) te Mortsel (België)

A temporary exposure of the Lower Miocene Kiel Member (Berchem Formation) is described, located south of Antwerp in the municipality of Mortsel (Belgium). The glauconitic sands were decalcified, given the absence of calcareous shells. Locally, pseudo-layering was observed due to rusty discoloration of the sediment, caused by post-depositional oxidation. Some small glauconitic sandstone fragments were found, containing an imprint of Haustator eryna (d’Orbigny, 1852).
