The Yucca Mountain area in southern Nevada is being evaluated for its suitability as a potential site for the construction of an underground, high-level nuclear waste repository. With support from the Department of Energy, the US Geological Survey is conducting detailed petrographic, geochemical, and isotopic analyses of samples collected from drill cores and from outcrops. The geochemical and isotopic compositions of the volcanic rocks of Yucca Mountain derive from those of their parental magmas, from changes resulting from the eruptive processes and from post-depositional alteration. In this study, geochemical and isotopic data were acquired on samples from reference sections selected in areas where the effects of the post-depositional alteration has been minimal. These data will be used as baseline information for delineating and correlating zonal features in the volcanic rock alteration that may occur in the thermal aureole of the potential repository after it has been loaded with nuclear waste.
