Code
ZEFC
Status
Informal (Van Adrichem Boogaert & Kouwe 1994).
Lithological description
Claystone and sandstone.
Depositional setting
Fluvial (?).
Definition of lower boundary
Not yet determined.
Definition of upper boundary
Not yet determined.
Thickness indication
Not yet determined.
Geographical distribution
Towards the edge of the basin, the evaporite members are progressively replaced by claystone and sandstone members. Wire-line logs generally provide sufficient ground for recognising the basin cycles in the fringe area. For those rare cases where no cycle (i.e. formation) boundaries can be distinguished, e.g. in the outer basinfringe-clastics, the informal formation name Zechstein Fringe clastics (ZEFC) has been proposed.
Regional correlation
