Description
Abstract
ABSTRACT Some triangular slope facets are localized to the south of Bardenas Reales (central-west of Ebro Basin), elaborated on Tudela Formation deposits, Aragonian in age. Three of them have been dated by OSL resulting on ages of: 35,588±2,488 yr. BP, 35,355±2,446 yr. BP and 40,185±2,411 yr. BP. The origin of these facets is ought to an alternation between acumulation and incision phases produced by vegetation cover variation percentage. Those vegetation cover changes are estimated to be due to climatic changes.
