Major Results
This study has contributed to the depiction of the Pyrenean planation surface on two main points: (i) it has confirmed that it formed below the present-day elevation of its remnants and was subsequently uplifted, and (ii) the Cretaceous 40Ar/39Ar ages of weathering have indicated that some Pyrenean low relief surfaces may be remnants of pre-orogenic surfaces.
