Abstract
Late Pleistocene glaciations in the NW Iberian Peninsula over Serra de Quei xa and Serra de Xures, all with granite substrata, were studied by mass spe ctrometry using cosmogenic Ne-21. Rock cores were drilled in glacial polish ed surfaces and push-moraine boulders, and were analyzed to determine their integral exposure time to cosmic rays. First results, which are consistent with the relative geomorphologic model estimates, allow the identification of at least three different glacial stages, with the latest terminating ab out 15 ka BP.
