The age of a basalt from Potrero de la Aguada, Sierra de Las Quijadas, province of San Luis (Argentina)

Abstract

?The age of a basalt from Potrero de la Aguada, Sierra de Las Quijadas, province of San Luis (Argentina)?. More than ten years ago, one of us gave the first radimetric dates for basalts from sierra de Las Quijadas (province of San Luis). Later, those were objected considering new dates. The revision was then necessary, and so now we put on the table a basalt of 106 ± 5 m.y., which is with security a product of the same efusive moment.
