Oosterhout Formation

NUOO

Formal (Doppert et al. 1975). Amended (Ebbing & De Lang 2003).

Light grey to greyish green very fine to medium sand, locally clayey, glauconitic, with shells. At the top, dark grey to greyish brown clay, silty or sandy. Shell banks (crags). Locally, yellow to reddish brown medium sand, fossiliferous, partly cemented by iron(hydr)oxides.

Shallow-marine (shelf and shoreface; clay with tempestites), estuarine, deltaic, beach and nearshore (sand and shell banks; Hodgson 1989).

Sharp contact with more glauconitic, finer and less shelly shallow-marine sand (Breda Formation) where the base is clayey, gradual transition where the base is sandy.

Locally exposed at the surface (yellow to reddish brown cemented sand). Elsewhere, gradual transition into (where top is sandy) or sharp contact with (where top is clayey) slightly coarser and less glauconitic shallow-marine sand (Maassluis Formation), sharp contact with coarser fluvial and coastal sand and gravel (Kiezeloolite, Waalre and Peize Formations), or gradual transition into aeolian or local river sand (Stramproy Formation).

Up to 150 m.

Landward transition into and interfingering with coastal-plain and fluvial deposits (Kiezeloolite Formation).

North Sea: Brielle Ground Formation (defined and mapped in conjunction with the British Geological Survey; Long et al. 1988; Rijsdijk et al. 2005: UK: informal Trimley Sands, Corraline Crag and Red Crag Formations (Mathers & Zalasiewicz 1988; Gibbard et al. 1998); GER: Nütterden and Weeze Schichten; BEL: Lillo, Poederlee, Kattendijke and Kasterlee Formations (Vernes et al. 2018).

late Miocene to Pliocene.

Named after the city of Oosterhout, in the southern Netherlands.

Kattendijk (non-glauconitic part), Luchtbal and Kallo Sands, part of the Merksem Formation, Lievelde Deposits, Scheemda Formation (cf. Van den Berg & Gaemers 1993).
