Lithological description
Dark to medium grey mostly shale and mudstone (compact bedded), also siltstone and fine sandstone (laminated or obliquely stratified), deposited as distal turbidites and less frequently as laminated hemipelagites; the decimetric sequences are most frequently (81%) Tde, with a mean thickness of 19 cm, less frequently (7%) Tcde and 12% Tbc(d)e; telson fragments of the Archaeostraca crustacean Ceratocaris sp. are not rare; characteristic is the bioturbation of the Te divisions, not present in the presumably underlying Ronquières Fm and the absence of the pyrite hemispheres often present in lower units.
Age
Based on the chitinozoans (E. lagenomorpha and B. lauensis): uppermost Gorstian and lower Ludfordian (Ludlow) (Van Grootel, 1990 ms).
Thickness
At least 24 m.
Area of occurrence
Only in the subsurface of the SW part of the Brabant Massif.
Type locality
Borehole in Bellegem, south of Kortrijk, (BGS N° 97E865 and 97E874).
