The Balbuena Formation, integrant of the Pampean magmatic arc in the Sierra de Ambargasta, Province of Santiago del Estero

A set of dikes in the Eastern Sierras Pampeanas (29°25′ - 29°35′S y 63°43′ - 64°00′W) trending from 90° to 120° azimuths and with thickness less than 10 m wide are assigned to the Balbuena Formation. These dikes are basaltic, andesitic to dacitic in composition representing basic to intermediate mem...
