Tracing the origin of organic matter in river deltas using the dual isotopic composition of carbon (δ 13 C and Δ 14 C)
River deltas play a crucial role in the global carbon cycle, acting both as significant carbon sinks and as sources of CO2 to the atmosphere. The Rhône River delta is a key site for studying these processes due to its high sedimentation rates and its unique radiocarbon signatures influenced by anthropogenic activities. This study compiles over 10 years of research to assess the sources and fate of organic matter (OM) in the Rhône River delta, usi…
U/Th and 14 C Crossdating of Parietal Calcite Deposits
14 C and U/Th methods were used to date three thin carbonate layers deposited on decorated walls of Nerja Cave (Malaga, southern Spain) in order to constrain the age of the parietal non-figurative marks situated under these carbonate layers. Modern formations were also dated to estimate the detritic contribution for the U/Th method and the dead carbon proportion for 14 C dating. We sampled two locations with ocher painting marks. In one case (mar…
Sur la présence d’ursus arctos au début de l’Holocène dans le Moyen Atlas (Maroc) - datations et implications paléoenvironnementales
Dans le Moyen Atlas, près de Boulmane les formations calcaires d’El Minchare abritent une grotte profonde (Ifri Oussaïd) s’ouvrant au-dessus du plateau à 2075 m d’altitude. Les fouilles de ce site ont livré, de 2005 à 2007, des charbons associés à plusieurs ossements dont au moins 156 restes d’ours brun (Ursus arctos) appartenant à cinq individus. L’étude paléontologique atteste d’un ours de petite taille (Ouchaou, 2008). Les niveaux à charbons d…
