During the late Maastrichtian to early Danian the Neuquén Basin of Argentina was adjacent to an active volcanic arc to the west and an extensive land area to the northeast. Mineralogical and geochemical studies of the Bajada del Jagüel in the Neuquén Basin indicate a generally warm climate with seasonal changes in humidity and an open seaway to the South Atlantic that maintained marine...

Late Cretaceous to early Paleocene climate and sea-level fluctuations : the Tunisian record

Adatte, Thierry ; Keller, Gerta ; Stinnesbeck, Wolfgang

In: Palaeogeography, Palaeoclimatology, Palaeoecology, 2002, vol. 178, p. 165-196

Climate and sea-level fluctuations across the Cretaceous–Tertiary (K–T) transition in Tunisia were examined based on bulk rock and clay mineralogies, biostratigraphy and lithology in five sections (El Melah, El Kef, Elles, Ain Settara and Seldja) spanning from open marine to shallow inner neritic environments. Late Campanian to early Danian trends examined at El Kef and Elles indicate an...
