Lauterecken formation
The Lauterecken formation is a lithostratigraphic rock unit of the Rotliegend of the Saar-Nahe-Basin in the history of the earth . It follows the Quirnbach Formation and is overlaid by the Meisenheim Formation . The chronostratigraphic dating is still uncertain. It is likely to be in the basal Permian ( Asselium ).
Naming and conceptual history
The Lauterecken formation is named after the town of Lauterecken in the Kusel district in Rhineland-Palatinate . The name was introduced in 1971 by Otto Atzbach and Klaus Schwab in the explanations of the geological map of Rhineland-Palatinate 1: 25000 sheet number 6410 Kusel as Lauterecken layers . Jürgen Boy and Jürgen Fichter used the term in 1982 in the form of Lauterecken layers . Karl Stapf then changed the term in 1990 in line with the guidelines for lithostratigraphy in the Lauterecken formation .
Definition, Correlation and Age
The formation consists mainly of gray, clayey to fine silty, mostly carbonate sediments, with a few conglomerates , coal seams and limestone. The deposits are also reddish in color in some sections of the profile. Their thickness varies from 200 m in the Kusel area to 350 m near Meisenheim, and 190 m in the Palatinate Mulde. The lower limit is formed by the base of the Feist conglomerate, the upper limit is the base of the Obereisenbach bank. The formation is lithologically divided into the following banks:
- Rötherhof Bank
- Medard Bank
- Tilting bench
- Wiesweiler Bank
- Odenbach bank (with coal seam)
- Feist conglomerate
There is no further breakdown into sub-information.
Storage room and fossils
The deposit area was predominantly characterized by large and mostly shallow lakes, which were crossed by rivers and built deltas in these lakes. The Feist conglomerate is to be interpreted as the deposit of a branched river system. Have been found in fossils: plant remains, ostracods , syncaride crabs , branchiopoda , mussels , xenacanthide sharks , hybodontide sharks , Acanthodier , bony fish , lungfish , coelacanths and rarely amphibians residues.
