The significance of scarp retreat for cenozoic landform evolution on the Colorado Plateau, U.S.A.

SCHMIDT, K. H.

Description :
In examining whether the denudational efficiency of scarp retreat was sufficient to account for the wide erosional gaps in the sedimentary cover, rates of scarp retreat were determined by using the information of dated volcanic material and by applying a new method, which calculates the amount of retreat from the width of beheaded valleys of known age. Rates of retreat range from 0.5 to 6.7 km/my. The results show that the rates of retreat are controlled by the thickness and resistance of the caprocks.
