AARD DER GRONDLAGEN
------------------------------------------------------------------------------
Reworked Lillo Formation:
Very compact heterogenous shell layer with reworked shell fragments, flint
pebbles and clay streaks.
Reworked Deurne Sands and Kattendijk Sands:
Grey green heterogenous slightly clayey glauconitic sand; fossiliferous
sandstones and concentrations of "Terebratula" specimens (probably derived from
the Deurne Sands); very rare reworked shell fragments (probably derived from
the kattendijk Sands); flint pebbles, bones and shark teeth.
Antwerpen Sands:
Dark green medium fine slightly clayey fosiliferous very glauconitic sand;
typical variable shell layers with the guide fossil "pectunculus pilosus" (=
glycymeris lunulata baldii (GLIBERT & VAN DE POEL, 1965));
Sample 17: thin shell layer with "pecten tigerinus" (= pseudamussium
(Zygochlamys) tigerinum (muller, 1776))
Sample 16: thin shell layer with the guide fossil
Sample 15: well developped compact shell layer with the guide fossil,
very rare bivalved spec.
Sample 14: nests of fragile shells
Samples 12-13: dispersed small shells; Gastropoda
Sample 11: shell layer with the guide fossil, sometimes bivalved
Sample 10: dispersed small shells
Samples 8-9: massive shell layer with the guide fossil; locally less
fossiliferous sand between the samples 8 and 9
Sample 7: massive shell layer with fragile smaller specimens;
"Panopoea Menardi" in situ
Sample 6: thin shell layer with more dispersed specimens
Sample 5: well developped shell layer with the guide fossil, rarely
bivalved, orientated in all directions
Sample 4: shell layer with 'turritella" passing into the shell layer
of sample 5
Sample 3: thin shell layer with the guide fossil, many bivalved
specimens or loose valves, often with convex side upwards
Sample 2: thin shell layer with dispersed often bivalved specimens of
the guide fossil; clay streaks and sandstones at the base
Sample 1: thin shell layer with loose valves of the guide fossil,
convex side sometimes upwards.
