Abstract:

On the basis of gravimetric data, gravity anomaly maps were made, together with isostatic and elastic thickness analyses, with the aim of characterizing the crustal structure of the San Rafael block, situated in the south of the province of Mendoza. Based on the interpretation of anomaly map obtained of EGM2008 model and of the Moho undulations, it was observed that the San Rafael block is located on a tectonic slope. The Moho under the block is situated at a depth of 40-45 km. The differences between the hydrostatic Moho and the gravimetric Moho results indicate a lack of a root of approximately 8 km under the San Rafael block, which shows a clear lack of isostatic equilibrium, with a lack of a root to compensate the topographic expression of the block. This, together with the elastic thickness values calculated, are indicators that show that the crust is rigid enough to support the block. © 2016 Asociación Argentina de Geofísicos y Geodestas.
