Abstract
This report summarizes the Cenozoic stratigraphy of sedimentary and volcanic rocks of the Marysvale volcanic field, Utah, by compiling all available published isotopic ages and by presenting new K-Ar, fission-track, and super 40 Ar/ super 39 Ar ages on igneous rocks of the volcanic field. This report shows that the igneous rocks of the field, which is one of the largest in the West, range from 34 Ma Oligocene to Quaternary.
