Late Quaternary morphodynamics in the Quebrada de Purmamarca, NW Argentina

&
This study aims to document the geomorphic, sedimentary and paleopedogenic archives in the Quebrada de Purmamarca. The paleoenvironmental interpretation of these archives and the reconstruction of landscape evolution are mainly based on field observations and geomorphological mapping (May 2008). A series of aggradational terraces mostly consisting of coarse debris-flow deposits are the main focus of this investigation. While the associated cut-and-fill processes are probably the result of an interplay between climatic and tectonic controls, the...
