De Lutte Formation

Code
DCHL
Status
Formal (Van Adrichem Boogaert & Kouwe 1995).
Lithological description

Predominantly reddish-brown, but also greenish-grey or variegated, silty to very fine-grained sandy mudstones. Sands are light grey, white, pink, or red, subangular to rounded, fairly- to well-sorted, fine- to medium-grained, with intercalations of coarse-grained, pebbly sand and conglomerate. Mudstone intercalations are between 10 and 100 m thick (average around 50 m). Carbonaceous particles are common in some intervals, but coal seams are practically absent.

Depositional setting

Predominantly well-drained, distal flood-plain setting. Sands mainly deposited by sheet floods or minor fluvial systems. Sandstone and mudstone beds reflects outbuilding of fluvial-fan systems onto the flood plain.

Definition of lower boundary

Placed at the top of the uppermost major sandstone bed of the Tubbergen Formation. Conformably overlies the Tubbergen Formation.

Definition of upper boundary

Truncated by an unconformity, which also marks the top of the Limburg Group. The unit can be succeeded by the Lower Rotliegend, Upper Rotliegend or Zechstein Group.
