29 p, 17.9 MB Interplay of Multiple Sediment Routing Systems Revealed by Combined Sandstone Petrography and Heavy Mineral Analysis (HMA) in the South Pyrenean Foreland Basin / Coll, Xavier (Universitat Autònoma de Barcelona. Departament de Geologia) ; Roigé, Marta (Universitat Autònoma de Barcelona. Departament de Geologia) ; Gómez-Gras, David (Universitat Autònoma de Barcelona. Departament de Geologia) ; Teixell Cácharo, Antonio (Universitat Autònoma de Barcelona. Departament de Geologia) ; Boya, Salvador (Universitat Autònoma de Barcelona. Departament de Geologia) ; Mestres i Andreu, Narcís (Institut de Ciència de Materials de Barcelona)
Combined sandstone petrography and heavy mineral analysis allow to decipher different sediment routing systems that could not be resolved by one method alone in the South Pyrenean foreland basin. We apply this approach to deltaic and alluvial deposits of the southern part of the Jaca basin, and in the time equivalent systems of the nearby Ainsa and Ebro basins, in order to unravel the evolution of source areas and the fluvial drainage from the Eocene to the Miocene.

22 p, 2.5 MB Links between fish abundance and ocean biogeochemistry as recorded in marine sediments / Kavanagh, Lucas (McGill University, Montréal. Department of Earth and Planetary Sciences) ; Galbraith, Eric (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals)
Fish populations are linked to ocean biogeochemistry by their reliance on primary production for food, and dissolved oxygen to breathe. It is also possible that marine fish modify biogeochemical dynamics, as do freshwater fish, through top-down trophic cascades, but there has been relatively little consideration of this possibility. [...]
