Silurian

Code
OS
Status
Informal. Only a few wells in the Netherlands have reached rocks older than the Devonian. The limited data do not allow for a formal lithostratigraphical description of the strata encountered. First mentioned in Van Adrichem Boogaert & Kouwe (1994).
Lithological description

Mudstones, dark grey to black.

Depositional setting

Foreland basin. Well O18-01 lies close to well 53/16-1 in the UK sector of the North Sea and the turbidite facies in both indicate a Silurian deep-water basin extending from the UK to Belgium and the Netherlands (Pharaoh 1999; De Vos et al. 2010).

Holostratotype
Depth (thickness) AH:
2952 - 3051 m (99 m)
Comments:
This is not a formal stratotype. This well merely demonstrates the possible presence of rocks of Silurian age in the Dutch subsurface.
