Code
ZEFRS
Status
Informal (Van Adrichem Boogaert & Kouwe 1994).
Lithological description
Sandstone.
Depositional setting
Sabkha to shallow marine, possible tidal influences (Geluk et al., 1996, 1997).
Definition of lower boundary
Not yet determined.
Definition of upper boundary
Not yet determined.
Thickness indication
Not yet determined.
Geographical distribution
In the basin fringe area, in places where a sandy development prevails, it may be in some cases impossible to distinguish the Red-brown Salt Clay Member with certainty. In such cases this unit and the Z1 Fringe Sandstone Member may be lumped with the overlying Z2 Fringe Sandstone Member into an informal unit: the Zechstein Fringe sandstone member (ZEFRS).
Regional correlation
Not yet determined.
Age
Wuchiapingian.
Type section
Well:
Depth (thickness) AH:
3836 - 3862 m (26 m)
Comments:
Example of sandy development, but no type section.
Origin of name
None.
Previous name(s)
None.
