This area, contammg many archaelogical sites, make possible the acoomplishment of some datations relating to different geomorphological processes. Two accumulative stages separated by erosion periods can be distinguished. The oldest accumulative level has finished elaborating after the Roman age; the la test accumulation does not provide any chronological accurancies, so long as it has not supplied any postroman remains. These changes in the geomorphological processes are supposed lO be due basically lo clima tic changes.
