Cronología potasio-argón del Complejo Efusivo Copahue-Caviahue, Provincia del Neuquén

Potassium-Argon chronology of the Copahue-Caviahue Effusive Complex, Neuquen Province. K/Ar ages from the Copahue-Caviahue Effusive Complex indicate that there are discrete time intervals between the principal volcanic events related with its evolution. The principal units may be correlated with thr...
