|Premise||Member defined by van Adrichem Boogaert and Kouwe (1997). This unit formed part of the Landen Clay Member of NAM and RGD (1980) . It is distinguished in Belgium as a member of the Heers Formation Marechal and Laga (1988) .|
|Derivatio nominis||The member has been named after the hamlet of Gelinden belonging to the municipality of Heers in Belgium.|
|Type section||Location map||See figure (pdf)|
|Depth||1395 to 1412 m|
|Length||17 m along hole|
|Reference||Type section is only valid for the Netherlands.|
|Definition||Hard and soft, mainly grey-white to yellow-brown, argillaceous marl with many burrows and yellow concretions. The lowermost beds generally consist of dark green marly clay.|
|Upper Boundary||The upper boundary is a more gradual transition to the Landen Clay Member, which is expressed on gamma-ray logs by higher readings for the Landen Clay Member. On resistivity logs the marl can be very clearly distinguished by higher readings than the overlying Landen Clay Member.|
|Lower Boundary||The lower boundary is formed by the sharp transition to the sands of the Heers Member, with relatively low gamma-ray readings.|
|Distribution||The member is present in the provinces of Noord-Brabant and the northern part of Limburg, northern Flevoland and the northern part of Gelderland.|
|Age||Late Paleocene (Thanetian). The foraminiferal assemblages belong to the FJ-Zone and are characterised by the presence of Trochammina inflata. Nannofossils are virtually absent.|
|Depositional Setting||Probably shallow open marine.|
|Sequence Stratigraphy||The unit seems to correspond with the Transgressive systems tract of cycle TA 2.1.|
