Résumé
Itinerary 8 aims to extend the understanding of Neogene landscape evolution already partly gained from the Roussillon, Conflent and Capcir basins. Focus is on the sediment record contained in the westernmost part of the Cerdagne Basin, which displays fossil-bearing late Miocene stratigraphic sequences. Another highlight is the population of range-flank erosion surfaces that grade to the margins of the clastic basin and of range-top erosion surfaces that have been preserved among the surrounding massifs of the Axial Zone. An additional focus is on tectonic geomorphology and on the impact of Pleistocene glaciation among the surrounding massifs. Late Pleistocene and older glacial landforms and deposits are particularly well documented because sequences of moraines and glacifluvial terraces are well preserved across the Cerdagne Basin floor.
