Boxtel Formation

Code
NUBX
Status
Formal (Schokker et al. 2005; Schokker et al. 2007).
Lithological description

Light yellow to dark brown very fine to medium sand, silty. Greyish brown to dark grey loam, sandy. Thin peat and gyttja layers, commonly sandy, partly detritic. Locally, fine to medium sand with granule lags. Palaeosols. Common cryoturbation.

Depositional setting

Aeolian (drift sand, river dune), periglacial aeolian (coversand, loess, desert pavement), periglacial lacustrine, small-scale fluvial or fluvioperiglacial (brook; including channel (sand), overbank and flood basin (silt and clay), periglacial slope, alluvial fan, swamp (peat and gyttja).

Definition of lower boundary

Usually, sharp contact with (partly ice-pushed) coarser fluvial and glaciofluvial deposits (Koewacht, Beegden, Kreftenheye, Sterksel, Waalre, Drente and Peelo Formations) or sandy silt (Wijchen Bed, Kreftenheye Formation). Locally, sharp contact with Neogene and Cretaceous marine deposits. Gradual transition into fluvial sand (Koewacht, Kreftenheye and Stramproy Formations), glaciofluvial sand (Schaarsbergen Member, Drente Formation) or peat (Woudenberg Formation). Offshore, commonly sharp contact with marine sand (Eem Formation).

Definition of upper boundary

Commonly exposed at the surface. Elsewhere, erosive contact with tidal sand and clay (Naaldwijk Formation), fluvial sand and clay (Kreekrak and Echteld Formations), glacial deposits (Dogger Bight Formation) or marine sand (Southern Bight Formation). Sharp contact with or gradual transition into peat (Basal Peat Bed, Nieuwkoop Formation) or into fine glaciofluvial sand (Well Ground Member, Dogger Bight Formation). Partly marked by bioturbation.

Thickness indication
Up to about 35 m in the Roer Valley Graben, up to about 10 m elsewhere

Previous name(s)
Merger of former Twente Formation, Asten Formation, Kootwijk Formation, part of the former Eindhoven Formation (all deposits south of the southernmost ice-sheet extent), and the fine-grained part of the Tienhoven Deposits (Van der Meene et al. 1988). Old Coversand (Van der Hammen 1971), Young Coversand. Includes river dune sand formerly assigned to the Kreftenheye Formation (Doppert et al. 1975).
