Journal ArticleDOI
Conjunctive use of spectral gamma-ray logs and clay mineralogy in defining late Jurassic–early Cretaceous palaeoclimate change (Dorset, U.K.)
TL;DR: In this paper, the spectral gamma-ray (SGR) response of resultant sediments is compared with the influence of organic matter on SGR, showing that elevated thorium may be used as a proxy for humid palaeoweathering.
Journal ArticleDOI
Subtropical climate conditions and mangrove growth in Arctic Siberia during the early Eocene
Guillaume Suan,Speranta-Maria Popescu,Jean-Pierre Suc,Johann Schnyder,Séverine Fauquette,François Baudin,Daichi Yoon,Karsten Piepjohn,Nikolay N. Sobolev,Loïc Labrousse +9 more
TL;DR: The early Eocene (ca. 56-47.8 Ma) was an interval of exceptional warmth with reducedpole-to-equator temperature gradients as discussed by the authors, which has proven difficult to reproduce with the most elaborate climate models.
Journal ArticleDOI
Paleohydrological and paleoenvironmental changes recorded in terrestrial sediments of the Paleocene-Eocene boundary (Normandy, France)
Sylvain Garel,Johann Schnyder,Jérémy Jacob,Jérémy Jacob,Christian Dupuis,Mohammed Boussafir,Mohammed Boussafir,Claude Le Milbeau,Claude Le Milbeau,Jean-Yves Storme,Alina I. Iakovleva,Johan Yans,François Baudin,Christine Fléhoc,Florence Quesnel +14 more
TL;DR: In this article, the authors focus on the organic matter content of the Vasterival section of the Cap d'Ailly area (Upper Normandy, France) in order to constrain the paleoenvironmental and paleohydrological changes that occurred at the Paleocene-Eocene boundary.
Journal ArticleDOI
Organic matter characterization and distribution in sediments of the terminal lobes of the Congo deep-sea fan: Evidence for the direct influence of the Congo River
Elsa Stetten,François Baudin,Jean-Louis Reyss,Philippe Martinez,Karine Charlier,Johann Schnyder,Johann Schnyder,Christophe Rabouille,Bernard Dennielou,Jennifer Coston-Guarini,Audrey M. Pruski,Audrey M. Pruski +11 more
TL;DR: In this paper, the authors determined the quantity and quality of the organic matter reaching the terminal lobe complex at five sites with marked morphological differences that may influence the distribution of organic matter.
Journal ArticleDOI
Depositional environments and characterisation of the organic matter of the Lower Mundeck Formation (Barremian ?–Aptian) of the Kribi-Campo sub-basin (South Cameroon): Implications for petroleum exploration
Marie-Joseph Ntamak-Nida,François Baudin,Johann Schnyder,Jean-Claude Makong,Paul Bertrand Komguem,Guy Martin Abolo +5 more
TL;DR: The shaly facies show good potential as oil-prone source rock, with TOC content around 4.4% and some intervals with an optimum potential to yield 45 kg hydrocarbons/t of rock as mentioned in this paper.
