AARD DER GRONDLAGEN
------------------------------------------------------------------------------
Reworked Lillo Formation:
Very coarse dark brown sand with dispersed flint pebbles and rare reworked
shell fragments; thick gravel with dark small rounded flint pebbles and shark
teeth at the base.
Kattendijk Sands:
Grey green fine slightly clayey glauconitic sand with dispersed flint pebbles,
nearly unfossiliferous; at the base gravel with flint pebbles, sandstones,
bones and shark teeth (sample 19c);
Antwerpen Sands:
Dark green medium fine slightly clayey fossiliferous very glauconitic sand;
typical variable shell layers with the guide fossil "Pectunculus pilosus" (=
Glycymeris lunulata baldii ( GLIBERT & VAN DE POEL, 1965));
Sample 19 a-b: nearly unfossiliferous except fragile shell layer with
"pecten tigerinus"; bioturbation sports; oxydation and
cementation of the sediment at the top
Sample 18: at the top thin shell layer; sandstones
Sample 17 a-b: thin shell layers
Sample 16: dispersed shells
Sample 15: very massive shell layer with loose valves of the guide
fossil and nests of shell fragments
Sample 14: nearly unfossiliferous
Sample 13: thin layer with shell fragments
Sample 12: very thin shell layer
Sampme 11: well developped shell layer with less specimens of the guide
fossil but more specimens of smaller species of Mollusca.
Sample 10: nearly unfossiliferous
Sample 09: fairly well developped shell layer, sometimes bivalved
specimens of the guide fossil
Sample 08: nearly unfossiliferous
Sample 07: massive shell layer with very small to large specimens of
the guide fossil
Sample 06: concentrations of shells with "Panopoea menardi" in situ
Sample 05: a-b: dispersed shells; bioturbation spots
Sample 04: thin shell layer with "Turritella" and the guide fossil
Sample 03: thin shell layer with the guide fossil
Sample 02: dispersed fragile shells of the guide fossil
Sample 01: thin shell layer with small slightly weathered specimens of
the guide fossil; sandstones.
