Resumen:
La Resina Complex: evidences for an AMCG suite in the sierra de La Huerta, San Juan province. This contribution presents a geological characterization of the proterozoic anorthosites, granites and amphibolites comprised in the La Resina Complex, located in western Sierra de la Huerta. The presence of massif-type anorthosite associated to granite suggests an AMCG (Anorthosite-Mangerite-Charnockite-Granite) suite. Particularly, the anorthosite bodies exhibit comparable characteristics to the ones from the sierra de Maz and Espinal, which also show a mesoproterozoic age. This would suggest a correlation with the anorthosites from the Grenville province and a common origin related to the Rodinia break-up.
