Deformation evidences on the glacier sediments from the northernmost el bolsón valley, northpatagonian andes

On the northeast face of Cerro Negro, in the northern extreme of the El Bolsón valley in the Patagonian Cordillera of Río Negro, a road cut left an outcrop of around 400-meters length of glacigenic deposits. In thislocation, some deformational features were observed, whose description and analysis a...

In thislocation, some deformational features were observed, whose description and analysis are objects of this work. Through the development of a series of sedimentary sections and profiles, the observed structures were interpreted as glaciotectonic in origin, resulting from the stresses applied from the movement of glaciers. However, still remain further research to be done in order to discard their potential connection with neotectonic processes. The folding direction indicates an advance from north to south, providing useful information on the study of ice flow direction in this Andean region during the Last Glacial Maximum. Moreover, two glacial advances were recognized, the first one having probably no geomorphological expression as it was overthrusted by a latter glacial advance. © 2015, Asociacion Geologica Argentina.
