Code
ZEZ1F
Status
Formal (Van Adrichem Boogaert & Kouwe 1994).
Lithological description
Grey to brownish limestone or dolomite; some anhydrite may be present in the unit. On wireline logs it often shows a blocky appearance. Some claystone beds occur in the unit. On the Peel Block, in adjacent parts of Germany and possibly elsewhere small bryozoan build ups have been encountered on structural highs (Geluk, 2000, 2007; Geluk & Röhling 2016).
Depositional setting
Shallow marine, carbonate slope.
Definition of lower boundary
Not yet determined.
Definition of upper boundary
The Z1 Fringe Carbonate Member is overlain by either the Z1 Middle Claystone or the Z1 Fringe Sandstone members.
Thickness indication
Up to 127 m.
Geographical distribution
