Controls on Quaternary incision of the Northern Pyrenean foreland: Chronological and geomorphological constraints from the Lannemezan megafan, SW France
We analyse the Lannemezan megafan in the Northern Pyrenean foreland (SW France). Cosmogenic nuclide surface exposure points to Quaternary abandonment and incision. Long-term incision of the foreland is linked to autogenic processes. Quaternary climatic cycles may have influenced the fan evolution.
