Title: Geology of volcanic and subvolcanic rocks of the Raton-Springer area, Colfax and Union Counties, New Mexico

Abstract

The most prominent geomorphic features of the Raton-Springer area are the widely distributed volcanic and subvolcanic rock formations, consisting of cinder cones, domes, lava-capped mesas, a domed sill complex, and dikes. Rock compositions range from mafic to salic, and many are alkalic. Rock names used in this report are based on the classification of La Roche and others (1980). Sixteen new K-Ar age determinations and three new fission-track age determinations are given here for selected rocks in this area. Reconnaissance geologic mapping of the Springer and Raton 30 feet x 60 feet quadrangles (September 1980 to May 1982) and preparation of the resulting maps provided much field and laboratory data about the igneous rocks of this part of the Great Plains. No published geologic map or report describes adequately the distribution and character of the alkalic rocks of this area. This report presents new descriptive information on field relations, chemical analyses, and K-Ar ages of igneous rocks in the area with the hope that others will be encouraged to investigate the geology of this interesting area in greater detail.
