Recent Tectonics in the Origin and Evolution of Gran Bajo del Gualicho,Argentina |
| |
| Abstract: | The results of an interdisciplinary research program on the Gran Bajo del Gualicho (Rio Negro, Argentina) are reported. Geological, morphological, gravimetric, and geochemical studies provide the basis for a reconstruction of the possible origin and evolution of this endorheic depression. On the basis of the available data, the hypothesis is advanced that the depression had a tectonic origin (according to NNW-SSE and ENE-WSW tectonic lines) and subsequently was shaped by exogenous forces that obscured the original fault scarps and caused the depression to assume its present characteristics. |
