Data release for geochronology and geochemistry of volcanic rocks in the Southern Rocky Mountains and Taos Plateau volcanic fields and other Oligocene to Pleistocene volcanic rocks within the southern San Luis Basin and San Juan Mountains, southern Colorado and northern New Mexico

Metadata Updated: October 28, 2023

The dataset includes whole-rock geochemistry and 40Ar-39Ar geochronology for Pleistocene to Oligocene volcanic and intrusive rocks. These data support figures and tables in days 2 and 3 of the Field-trip guide to continental arc to rift volcanism of the southern Rocky Mountains-Southern Rocky Mountain, Taos Plateau, and Jemez Mountains volcanic fields of southern Colorado and northern New Mexico (Thompson and others, 2022). Additional 40Ar-39Ar geochronology data are included for age reported in the Geologic map of Ute Mountain quadrangle (Thompson and others, 2014b) and the Geologic map of Sunshine quadrangle (Thompson and others, 2014a). Other samples not associated with any of these referenced publications are also included. > There may be slight variation in the ages reported here and other previously reported ages on the geologic maps for the Sunshine and Ute Mountain quadrangles (Thompson and others 2014a,b) and some ages originally reported on the Geologic map of the San Antonio Mountain area (Turner and others, 2017) due to statistical methods used in calculating the age.
