Comments on “Quaternary landscape evolution and erosion rates for an intramontane Neogene basin (Guadix–Baza basin, SE Spain)” by J.V. Pérez-Peña, J.M. Azañón, A. Azor, P. Tuccimei, M. Della Seta, M. Soligo, (2009) Geomorphology 106, 206–218

Pérez-Peٌa et al. (2009) recently estimated erosion rates for an intramontane basin based on the age of the petrocalcic horizon developed in the uppermost basin fill surface. This new interpretation contradicts well-established and reliable evidence for the origin of the travertines deposited after this surface was cut by a new exorheic drainage system. We argue that their interpretations are incorrect and that they have ignored much of the previous dating and field geomorphological evidence. Morphological, sedimentary and chronological evidence indicate that the reported incision rates are incorrect.
