GONZLEZ DAZ, Emilio F.. Doctor Jorge Polanski (1892-1975). Rev. Asoc. Geol. Argent. [online]. 2011, vol.68, n.3, pp.357-364. ISSN 0004-4822.

Jorge Polanski abandoned previous orientation in geoform studies, more related to primary geographical concepts and, determining their real geomorphological identity, established a before and after in Argentina in the analysis of landscape geoforms. Polanski mostly follows the ideas of William Morris Davis, and he was in fact one of the leaders of the davisian school in our country. The geomorphological analysis of Polanski was based in the relationship between development and landscape evolution with geological structure, replacing old interpretations based on static principles and genetic processes that lack a precise definition. His concept of geomorphic unit explains the development of land morphology as a result of geomorphological processes and geological structure, coinciding in this way with the european concept of morphostructure. Polanski recognized the geoforms that characterized the morphostructure of the Bloque de San Rafael, Mendoza province, roughly known or incorrectly interpreted at the time, and characterized the piedmont environment, between the Mendoza and Diamante rivers. His large article of 1962 on this topic constituted a milestone reference on geomorphology, introducing new concepts as pediment, pedimentation o exhumed peneplain.

Keywords : Geomorfology; Morphogenesis; Geomorphological map; Geomorphic unit; San Rafael Block.
