Description

Description

Mergel mit linsenförmigen Kalkbänken. Reich an biogenen Komponenten: Korallen, Brachiopoden, Mollusken. Mehrere Meter mächtige Folge heller grobbiodetritischer Kalkbänke und weisser Mergellagen mit Terebrateln, deren oberste zahlreiche, bis 2cm grosse Onkoide enthält.

Thickness

Max. 1 m (Gonzalez & Wetzel 1996). Faible épaisseur d'env. 3–5 m (Fischer et al. 1971), voire max. 10–20 m dans la région du Chasseral (Aufranc et al. 2017).

Dating Method

Ammoniten: The basal Movelier Beds were deposited during the latest Parkinsoni Zone as indicated by several finds of Parkinsonia planulata Quenstedt and Parkinsonia parkinsoni Sowerby. A few fossils document that the upper Movelier Beds could be of earliest Bathonian age (e.g. Prinsonia sp., from Les Malettes, Canton Jura). However, these finds have all been made by private collectors and are not exactly located in sections (Gonzalez & Wetzel 1996).

Conditions of formation

On top of the hardground that sealed the Upper Oolitic Series, a diverse fauna lived in marly background sediments (Movelier Beds). The substitution of oolites by marls was interpreted by Gonzalez (1996) as a relative highstand of sea-level. The sedimentation was controlled by storms in bathymetrically deeper areas in the east and west and might have been influenced by tides in some areas in the western and central Jura (Gonzalez 1993). The dominant transport directions were again from north to south, showing a dominance of ebb-tides. In some western areas coral agglomerations occur. (Gonzalez & Wetzel 1996).

They consist of marls alternating with lenticular limestones, both rich in complete as well as destroyed biogenous components, such as corals, brachiopods and mollusks.
