Abstract

I welcome the opportunity provided by Demant and Vincent's discussion (1978) of Mahood (1977) to correct an error in my original interpretation of the geological evolution of the Sierra La Primavera. The paper was based on observations made during a single field season and on less than a dozen K-Ar dates; I attempted to indicate the preliminary nature of my conclusions in the title of the article. As pointed out by Demant and Vincent, the fundamental error in my interpretation was the assumption that the Tala Tuff was one of the younger eruptive units at Primavera when, in fact, it is one of the older. In this reply, I would like first to present my revised view of the geologic evolution of the Sierra La Primavera and, second, to reply specifically to som of Demant and Vincent's points... In order to continue, download the full paper in PDF.
