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. [...]
