Abstract

Triangular slope facets or talus flatirons are presented as a useful tool for the calculation of scarp retreat rates in arid regions. In the central sector of the Ebro Basin, sequences of talus flatirons have been developed around mesas capped by Miocene limestone. These talus flatirons are grouped in 4 stages of slope evolution. The scarp retreat rate is related to the lithological and structural features of both the caprock and the underlying clay sediments and to the paleoclimatic evolution of the region that controls the intensity of weathering and water erosion processes that affect the slope system
