Miocene mollusc-bearing sediments were encountered on dumping places on the left bank of the river Scheldt near the city of Antwerp. These sediments are proven to originate from excavations for the underground railway in the centre of Antwerp (Teniersplaats-Keiserlei). Unfortunately the unusual digging methods made in impossible to study the section in the excavation. From the sediments on the dumping place and from informations obtained on the spot, it can be determined that the Oligocene Septaria clay at this place is overlain by some 20 meters of Miocene sands, in which both the Sands of Edegem and the Sands of Antwerp are represented, on top of which some six meters of Pliocene/Plistocene deposits occur.
