Largest volcanic field within the Rio Grande Rift and unusual silicic shield volcanoes
The Taos Volcanic Field is the largest volcanic field within the Rio Grande Rift. It is petrologically and volcanologically diverse, including compositions from tholeiite to rhyolite, and vent morphologies from cinder cones to steep-sided domical volcanoes. The field covers over 7,000 km2 and shares the broad valley floor with the Rio Grande which cuts through extensive sheets of thicks lavas, the Serviellta basalts, to form the Rio Grande Gorge. It is bounded on the east side by the Sangre de Cristo Mountains and on the west by the Tusas Mountains. On the north it terminates near the Colorado border and on the south squeezes into the narrow constriction between the Taos basin and the Espanola basin.
