Lithocodium and Bacinella signature of a late Hauterivian, local microbial event: the Urgonian limestone in South-East France
Autor: Marc A. Conrad, Bernard Clavel
Publikováno v: Geologia Croatica, Vol 61, Iss 2-3, Pp 239-250 (2008)
Sediment binding crusts of Lithocodium aggregatum and associated Bacinella irregularis abound in a shallow water limestone layer, in South-East France. The sudden appearance of these crusts denotes a local, conspicuous change in the otherwise balance

Revised dating of the major earliest Cretaceous transgression in S Aquitaine (SW France)
Autor: Bruno Granier, Bernard Clavel
Publikováno v: Cretaceous Research
Cretaceous Research, Elsevier, 2019, 99, pp.246-254. ⟨10.1016/j.cretres.2019.03.004⟩
The oldest dating of the earliest Cretaceous transgression in S Aquitaine (SW France) was long considered Aptian. In 1954, Cuvillier and Debourle report from the subsurface the find of a microfossil assemblage that they ascribe to the Valanginian. In

Comments on 'Estimating the impact of early diagenesis on isotope records in shallow-marine carbonates: A case study from the Urgonian platform in western Swiss Jura' by A. Godet et al. [Palaeogeography Palaeoclimatology Palaeoecology 454 (2016) 125-138]
Autor: Bernard Clavel, Jean Charollais, Bruno Granier
Publikováno v: Carnets de géologie (Notebooks on geology). 16:417-429
A recent paper by Godet et al. on Urgonian carbonates from the Swiss Jura concluded that diagenesis may hinder chemostratigraphic correlations of deep- to shallow-water facies. Although we agree with this conclusion we question their arguments and in

The Cretaceous of the Swiss Jura Mountains: an improved lithostratigraphic scheme
Autor: Bernard Clavel, Bruno Mastrangelo, André Strasser, Antoine Pictet, Marc A. Conrad, Jean Charollais
Publikováno v: Swiss Journal of Geosciences. 109:201-220
In the course of the HARMOS project of the Swiss Geological Survey, the lithostratigraphic subdivisions of the Cretaceous sedimentary rocks outcropping in the Swiss Jura Mountains were revisited. New formation names are proposed where only inadequate

Ammonitofaune du Barrémien de la coupe de L'Estellon (Baronnies, France) : résultats biostratigraphiques préliminaires
Autor: Robert Busnardo, Jean Charollais, Bernard Clavel, Bruno Granier
Publikováno v: Carnets de géologie (Notebooks on geology). :139-162
L'etude de l'ammonitofaune de la coupe de L'Estellon (departement de la Drome, France) permet de dater les episodes de la sedimentation gravitaire dans ce secteur de la Fosse vocontienne. Ils couvrent pratiquement l'ensemble du Barremien, depuis la Z

Mapping the rise and demise of Urgonian platforms (Late Hauterivian - Early Aptian) in southeastern France and the Swiss Jura
Autor: Marc A. Conrad, Jean Charollais, Robert Busnardo, Bruno Granier, Bernard Clavel
Publikováno v: Cretaceous Research. 39:29-46
Lower Cretaceous carbonate deposits historically called “Urgonian limestones” are widely exposed around the margins of the Vocontian basin in southeastern France and in the adjacent Swiss Jura. This paper presents the history of their rise, growt
