Reusel Member NLLFR


Premise Member defined by van Adrichem Boogaert and Kouwe (1997). In the NAM and RGD (1980) Nomenclature this interval has been erroneously interpreted as Ieper Clay Member and Brussels Sandstone Member.
  The unit can be correlated with the succession ranging from the Halen Member (base) to the Grandglise Member (top) of the Hannut Formation of the Belgian stratigraphy Marechal and Laga (1988) .
Derivatio nominis Named after the village of Reusel in the province of Noord-Brabant, in the vicinity of the type well.

Definition In the southeastern Netherlands the unit consists of two to three coarsening-upward sequences. The basal one is a small-scale alternation of hard siltstone and shale layers, capped by a thin clean sand. The upper unit has a sandier character with again a relatively clean thin sand at the top. The calcium-carbonate content decreases upwards, whereas the glauconite content increases in that direction leading to a soft-green colouring. The overall colour is light grey.
Upper Boundary The boundary with the conformably or slightly unconfomably overlying Basal Dongen Sand Member may be rather indistinct. However, the upper part of the Reusel Member is a coarsening-upward succession of, generally, more argillaceous, small-scale alternation of sand and clay layers with higher gamma-ray readings opposed to the clean, washed-out, fining-upwards Basal Dongen Sand with very low gamma-ray readings.
Lower Boundary .The lower boundary with the Landen Clay Member is somewhat gradual.
Distribution The unit is only present in the province of Noord-Brabant and in northern and central Limburg.
Age Late Paleocene. The upper part of the unit is generally barren, but near the base, zone NP 8 has been identified. The lowermost part of the member contains foraminiferal assemblages belonging to the FJ-Zone.
Depositional Setting Most likely, the unit is the distal marine expression of the northward progradation of a deltaic system. It corresponds with a probably NW-SE oriented deltaic lobe (perpendicular to the palaeo-coastline), which thins out northwards.
Sequence Stratigraphy The unit seems to correspond with the Late Highstand systems tracts of cycle TA 2.1, TA 2.2 and possibly TA 2.3.
