Estimations of surface denudation are presented on three different types of relief, which have been eroded since the Late Miocene. These investigations were made in two steps: 1. the digital reconstruction of the initial surfaces and 2. calculating the altimetrically differences between these and the actual surfaces. Our results show an erosion of a few hundreds meters, which are compatible with the earlier geomorphological estimates, but are in a great contrast, when compared with the much greater (appr. 6 km) values yielded by the thermochronological analyses.
