|Premise||Definition extended after NAM and RGD (1980) . The lithological affix has been deleted.|
|Derivatio nominis||Named after the Eem-harbour in Rotterdam.|
|Type section||Location map||See figure (pdf)|
|Depth||1759 to 1778 m|
|Length||19 m along hole|
|Reference||NAM and RGD (1980)|
|Definition||A thin claystone section intercalated between the De Lier Member and the IJsselmonde Sandstone Member or Nieuwerkerk Formation, with marine fossils.|
|Upper Boundary||The upper boundary with the De Lier Member is of a more gradual nature.|
|Lower Boundary||The lower boundary, with the IJsselmonde Sandstone Member, is well-defined at the top of the sandstone. To the southeast of the basin, the member can overlie the coastal/fluvial-plain deposits of the Nieuwerkerk Formation|
|Distribution||Southern margin of the West Netherlands Basin, where the IJsselmonde Sandstone Member (or equivalent Nieuwer-kerk Formation) and the De Lier Member occur. Towards the basin centre the member loses its identity in the main Vlieland Claystone Formation.|
|Age||Late Barremian. Assemblages characterised by the pres-ence of Pseudoceratium pelliferum and Odontochitina operculata.|
|Depositional Setting||Palaeogeographical data and facies association suggest a marginal-marine deposition.|
|Sequence Stratigraphy||This member reflects the LZB 3.5 Maximum Flooding.|
