Stacked fining-upward sequences. Grey ro greyish white very fine to very coarse sand, micaceous, multi-coloured with reddish particles in coarse fraction, locally gravelly (in lags). Bluish grey to brownish grey clay beds and laminae, silty to sandy, with sporadic peat layers and siderite.
Fluvial and estuarine (Rhine), including high-energy channel (lags marking channel base) and point bar, as well as low-energy abandoned channel (laminated clay with interbedded sand), floodplain (humic fine-grained facies with local peat or lignite layers), levee and crevasse (intercalated sand and clay). Estuarine and lagoonal (silty clay with local organic and sand layers).
Locally, gravel lag. Unconformable, commonly sharp contact with paler fluvial sand and clay (Kieseloolite Formation) or glauconitic and shelly shallow-marine sand and clay (Breda, Oosterhout and Maassluis formations).
Commonly, sharp contact with paler small-sclae fluvial or aeolian sand (Stramproy Formation), coarser and more gravelly fluvial sand (Peize, Beegden, Sterksel, Urk and Kreftenheye formations), or shelly marine sediment (Eem Formation). Gradual transition into tidal sand and clay (Naaldwijk Formation).
