Background
The early Pleistocene La Reforma caldera lies along the Gulf of California immediately east of Tres Vírgenes volcano and SE of the late-Pleistocene El Aguajito caldera. The roughly 10-km-wide caldera contains basaltic, andesitic, and dacitic lava flows, and rhyolitic lava domes. A prominent arcuate caldera rim extends from La Reforma along the NW coast to near Punta Las Cuevas on the SE coast. The age of the caldera was determined by the K-Ar method to be between 1.6 and 1.4 million years old (Ma). A 1.09 +/- 0.11 Ma age was obtained on a ring-fracture lava dome. Andesitic lava flows were erupted on the flanks of the caldera both before and after caldera formation.---
