RT Journal Article T1 Depósitos de dunas ascendentes en la sierra de Los Tarjados, provincia de La Rioja, Argentina T1 Climbing dunes deposits in sierra de Los Tarjados, La Rioja province, Argentina A1 Tripaldi, A. A1 Limarino, C. O. AB Eolian climbing dunes found in the sierra de Los Tarjados (south of the La Rioja province> Argentina) are described in this paper. According to their morphology two mayor types of dunes have been recognized: 1) climbing dunes associated to ramp deposits, which can ascent the mountain front; and 2) climbing dunes do not related to ramps and where deflationary channel developed between the dune front and the cliff.
