AARD DER GRONDLAGEN
------------------------------------------------------------------------------
"Quaternary":
dark brown clayey sand with rare reworked shell fragments and dispersed flint 
pebbles.

Reworked Lillo Formation:
Very compact heterogenous shell layer with reworked shell fragments, flint 
pebbles, sand and clay streaks.

Kattendijk Sands:
Grey green fine slightly clayey fossiliferous glauconitic sand; shell layer 
with the guide fossil "Isocardia cor" (= Glossus humanus (LINNAEUS, 1758)); 
dark rounded flint pebbles; at the undulating base gravel with dark rounded 
flint pebbles, bones, clay spots, sandstones often including "Ditrupa" and 
Gastopoda, and shark teeth.

Deurne Sands:
Grey green medium fine locally fossiliferous glauconitic loose sand; typical 
whitisch bioturbation spots with dark contour of glauconite; dispersed nests of 
Bryozoa, "Distupa" and "Mannia nysti" (DEWALQUE)"
(Brachyopoda); poorly developped gravel at the base with dark small flint 
pebbles, small bone fragments and rare shark teeth.

Antwerpen Sands:
Dark green medium fine slightly clayey fossiliferous very glauconitic sand, at
