|Premise||Member defined by van Adrichem Boogaert & Kouwe (1994).|
|Type section||Location map||See figure (pdf)|
|Depth||3836 to 3851 m|
|Length||15 m along hole|
|Definition||The Z2 Fringe Sandstone Member consists of a light-coloured sandstone, fine- to medium-grained and well-cemented with calcite, dolomite and silica cement, and some interbedded claystones that increase in abundance towards the centre of the basin.|
|Lower Boundary||Along the basin fringe, in places where a sandy development prevails, it may be impossible to distinguish the underlying Red-brown Salt Clay Member with certainty. In such cases this unit and the Z2 Sandstone Member may be lumped with the underlying Z1 Sandstone Member into an informal unit: the Zechstein Fringe sandstone (ZEFRS). An example of such a development is found in well Q16-02 (see pdf) , interval 3836 - 3862 m below rt.|
