Descripción
The results obtained in this work evince that the metallic mineral deposits located in the northern region of the Chilean-Pampean flat slab (in northern Chile and north-western Argentina), at approximately 27 300 S, would be related to the subduction of the Copiapo aseismic ridge. The analysis of the gravity anomalies and vertical gravity gradient allows inferring a deflection and truncation of the main trend of the Andean structures at the extrapolated zone of the Copiapo ridge beneath South America. Thus, the general NNE-trend of the Andean structures are rotated locally to an ENE-strike within the area of the Ojos del Salado e San Buena Ventura lineament. We explain that this anomalous behavior of the gravity derived anomalies is related to the deformational effects imprinted by the ridge subduction. Regions with a low subduction angle (<30 to horizontal) are related to large mineralization due to fluids released by dehydration of the subducting crust. In addition, a higher degree of mantle melting could be produced by a thicker oceanic crust. Therefore, we interpret that the processes associated to the subduction of the Copiapo aseismic ridge (emplaced on a thickened oceanic crust due to a local compensation of the seamounts) are the cause of formation and emplacement of big metallic mineral deposits in this region of Chile and Argentina.
