Sr isotopic geochemistry of voluminous rhyolitic ignimbrites and related rocks, Batopilas area, western Mexico

Abstract

The middle Tertiary ignimbrites of the Sierra Madre Occidental of western Mexico form the largest continuous rhyolitic province in the world. Minor amounts of intermediate lavas occur interlayered with the ignimbrites, and Sr isotope data on the complete range in rock compositions must be considered when evaluating hypotheses for the origin of the rhyolites. Initial 87Sr/86Sr ratios of andesites, dacites and rhyolites from the Batopilas region of western Chihuahua lie in the range 0.7042–0.7050, showing no systematic variation with rock composition. The data reported here support a crystal fractionation hypothesis for the origin for the voluminous rhyolitic ignimbrites.
