BackgroundThe Camargo volcanic field is located in the northern Bolsón de Mapimí graben in north-central México, about 150 km SW of Big Bend National Park in Texas. More than 300 volcanic vents, mostly cinder cones and lava cones, are located in a broad 2500 km2 lava plateau that extends 60 km E-W and 70 km N-S. It is mostly Pliocene in age, but an early Pleistocene age of 1.43 +/- 0.05 Ma was obtained on one sample. The best-studied vent of the field is 1.63 Ma Cerro el Salto (also known as La Olivina), a cinder cone whose spinel-lherzolite xenoliths were once mined for peridot.
