Background
The San Ignacio volcanic field lies north of the town of the same name and east of the town of Vizcaino. Miocene tholeittic basaltic-andesitic lava flows and somewhat magnesian Pliocene-to-Pleistocene andesites emitted from dozens of cinder cones overlie Tertiary sediments (Pallares et al., 2007; Calmus et al., 2003). Surface morphology implies that these Plio-Pleistocene flows were likely highly viscous, compared to their more fluid Miocene counterparts (Pallares et al., 2007). The San Ignacio field dates to about 0.65 to 5 Ma; most of the volcanic activity at this center occurred during the Miocene and early Pliocene (Calmus et al., 2003).---
