Background:
The Cerro Mencenares volcanic complex along the Gulf of California is situated at the northern extent of the Loreto Basin, SE of Bahia Concepcion (Dorsey and Umhoefer, 2000). It's eruptive history, which involves three eruptive events, likely played a role in the development of the Loreto Basin. Cerro Mencenares itself is a large stratovolcano; the complex consists of this composite cone and several peripheral centers that cover an area of about 150 km2 (Bigioggero et al., 1995). The volcanic products generally consist of Pliocene to lower Pleistocene andesitic to rhyolitic domes, flows, and pyroclastics (San Juanico Unit), along with dacitic and andesitic-basaltic lava flows (Mencenares Unit) (Dorsey and Umhoefer, 2000; Bigoggero et al., 1995). Younger silicic domes and minor basaltic lava flows make up the San Basilio-San Juan Unit (Bigioggero et al., 1995). The volcanic tuffs and breccias on the flanks of the complex are often interbedded with marine mudstones and limestones (Bigioggero et al., 1995; Dorsey and Umhoefer, 2000).---
