2.5.17 Rekkem Formation - REK

Author: Van Grootel, 1990 ms

Description: Dark and medium grey, silty and clayey shale, with no sandstone present; compact, laminated or obliquely stratified; deposited as distal turbidites; 82% of the sequences are Tde, with a mean thickness of 3.5 cm; less frequently (3%) Tc(d)e and 15% Tbc(d)e; characteristic is the bioturbation with irregular tubes and absence of hemispheric pyritospheres.

Stratotype: borehole in Rekkem, south-west of Kortrijk, (BGS N° 96E77).

Area: Only in the subsurface of the SW part of the Brabant Massif.

Thickness: at least 13 m.

Age: Based on the chitinozoans, a tentative Pridoli age is proposed (Van Grootel, 1990 ms).
