Naaldwijk Formation

Code
NUNA
Status
Formal (Weerts 2003).
Lithological description

Highly variable. Generally, grey fine to medium sand, calcareous, shelly. Grey to blue silt and clay layers, organic, shelly. Common coarse lags and clayey fills. Thin discontinuous peat layers.

Depositional setting

Shoreface, nearshore, coastal dune, beach, beach ridge and washover, beach plain, tidal basin (including estuarine, lagoonal, tidal channel, channel margin, sandy tidal flat, mudflat; Westerhoff et al. 2003; Weerts 2003).

Definition of lower boundary

Regionally, unconformable contact with or gradual transition from clay or fine sand into peat (Basisveen Bed, Nieuwkoop Formation). Where this peat is absent, unconformable contact, commonly marked by a channel lag, with till (Drente Formation), marine sand and clay (Eem Formation), medium to coarser fluvial sand and gravel (Kreftenheye Formation), periglacial sand and silt (Boxtel Formation), or fluvial silty clay (Wijchen Bed, Kreftenheye Formation; Echteld Formation).

Definition of upper boundary

Commonly exposed at the surface or seabed. Locally covered by peat (Nieuwkoop Formation), fluvial sand and peaty clay (Echteld Formation), or open-marine sand (Southern Bight Formation) or mud (Urania Formation) (Rijsdijk et al. 2005).

Thickness indication
Up to about 75 m underneath high dunes and in thick channel fills.
Geographical distribution
The seaward boundary with the marine Southern Bight Formation is diffuse. The lower shoreface, formed under the influence of shoaling waves, grades into the inner shelf where wave processes have less impact on the seabed. The depth of this transition varies as a function of wave climate, and is typically between 15 and 20 m.
