Pressure–temperature–deformation–time path of a deformed garnet-bearing granite from the Paleoproterozoic Tandilia Belt, Río de la Plata Craton of Argentina
Abstract:The pressure-temperature (P-T) evolution of a deformed garnet-bearing granite of La Virgen hill, located 25 km south of the town of Azul, Argentina, was studied as an example of the slightly peraluminous and deformed granites widespread in the Paleoproterozoic Tandilia Belt of the Rio de la Plata Craton. An early isobaric magmatic-submagmatic cooling path followed by exhumation was derived by the appraisal of microstructures, chemical compositions of minerals and P-T pseudosection modeling in the system Si-Ti-… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
