    • Data release of geospatial map database, argon geochronology and geochemistry data for: Geologic map of the San Antonio Mountain area, northern New Mexico and southern Colorado

    Metadata Updated: January 20, 2026

    This dataset accompanies publication "Geologic map of the San Antonio Mountain area, northern New Mexico and southern Colorado". Data presented here include the digital geologic database, 40Ar/39Ar geochronology and major and trace element chemistry from lava flows and an ignimbrite. The geologic database includes spatial feature classes and non-spatial tables that collectively contain the geologic information presented in the map plate. 40Ar/39Ar geochronologic analyses and geochemical data constrain temporal and stratigraphic relations for deposits associated with the Taos Plateau volcanic field, late Oligocene to Miocene basaltic volcanism, and the San Juan Mountains locus of the Southern Rocky Mountains volcanic field along the western margin of the San Luis Basin situated in northern New Mexico and southern Colorado, USA.
