Micromorphology and macrofabrics of Late Quaternary sediments in the Aragonese Pyrenees, Spain

  • Within the scope of the research project Post-LGM pedogenesis and geomorphodynamics in the Aragonese Pyrenees we used a combination of field and laboratory methods to differentiate and classify Late Quaternary sediments. Our analyses indicate no post sedimentary erosion of the LGM lateral moraines in the Aragon and Gallego valley. Precipitation of calcium carbonate led to the fixation of the diamictons and thus stabilized the glacial landforms. Clasts in the glacial sediments are orientated parallel to the Pleistocene glacial flow direction and therefore underpin the stability of the glacial deposits during paraglacial times. Grain size analyses and OSL ages indicate the covering of glacial sediments by an eolian deposit before the onset of the Holocene.
