Abstract The Early Cretaceous Weissert event, characterized by a positive carbon isotope excursion and coincident with the Paraná‐Etendeka volcanism, saw a biogeochemical chain of events that ultimately led to an increase in carbon burial. A concl

International audience; Sediment routing systems (SRSs) are a critical element of the global response to ongoing climate change. However SRS response to climate forcing is complex, fragmentary, and obscured when viewed over short, human time scales (

International audience; Variscan shear zones in the Armorican Massif represent sites of strong fluid‐rock interaction. The hydrogen isotope composition of muscovite (δDMs) from syntectonic leucogranite allows to determine the source of fluids that

While marine records of the Eocene-Oligocene transition indicate a generally coherent response to global cooling and the growth of continental ice on Antarctica, continental records indicate substantial spatial variability. Marine Eocene-Oligocene tr

Publikováno v: Journal of African Earth Sciences. 104:140-158

The Early Cretaceous Bima Sandstone is a continental succession in the Upper Benue Trough, Nigeria formally divided into the Lower, Middle and Upper Bima Members. Sedimentological data presented here indicates a two member model (Lower and Upper Memb
