This study relates to the input and fate of fossil organic matter (FOM) in the modern environment, and focuses on two experimental watersheds overlying Jurassic marls: Le Laval and Le Brusquet (1 km 2 in area), located near Digne, Alpes-de-Haute-Provence, France. Considering that FOM delivery is mainly a result of different processes affecting sedimentary rocks [(bio)chemical and mechanical wea...

Des dépôts offshores localisés à l’Est de la marge d’Abidjan (Côte d’Ivoire) ont fait l’objet d’analyse palynologique et palynofaciologique. Elle a porté sur des déblais forage partir desquels trente-deux (32) paires lames minces palynologiques été confectionnées. L’objectif était mettre en évidence les étages du Tertiaire limite K-Pg par palynomorphes stratigraphiques déterminer environnements...

Ditch samples from AP-4, ER-51 and UK-2 offshore Niger Delta were subjected to biostratigraphic organic geochemical analyses which entail foraminiferal, palynological, Spore Colour Index (SCI), Rock-Eval Pyrolysis Fourier Transform Infrared Spectroscopy (FTIR) analyses. The results have established N19 N17; N17, N16 N15; N9 N8 biozones; P600 P700 palynological zones. dominance of palynomaceral ...

Abstract Fire regimes are changing due to both anthropogenic climatic drivers and vegetation management challenges, making it difficult determine how climate alone might influence wildfire activity. Earth has been subject natural-background variability throughout its past variations in Earth’s orbital parameters (Milkankovitch cycles), which provides an opportunity assess climate-only driven wi...
