Beschreibung
The Moctezuma volcanic field occupies a 380 km2 area along the foothills of the Sierra Madre Occidental in NW México. An early stage of tholeiitic basaltic volcanism originating from fissures along the eastern boundary of the graben produced a broad mesa within a large graben in the Moctezuma Basin. Younger alkalic basaltic volcanism produced five scoria cones concentrated along a crudely N-S trend in the center of the graben. These produced lava flows that traveled primarily SW. The youngest cone is Cerro Blanco, which produced lava flows to the SW and was Potassium-Argon dated at about 0.53 +/- 0.2 million years.---
