The Absaroka volcanic field is comprised of predominant andesitic volcaniclastic rocks and less abundant potassium-rich mafic lavas (shoshonites and absarokites). Strontium and lead isotopic variations preclude a simple derivation from an isotopicall

Variations in the ratio of K(2)O to SiO(2) in andesitic rocks suggest early and middle Cenozoic subduction beneath the western United States along two subparallel imbricate zones dipping about 20 degrees eastward. The western zone emerged at the cont

The Heart Mountain detachment fault is a nearly horizontal fault along which a large slab of nearly flat-lying Paleozoic sedimentary strata and Eocene volcanic rocks became detached and slid laterally southeastward. During sliding, the slab broke up
