Peralkaline Silicic Volcanic Rocks in Northwestern Nevada

Donald C. Noble, D.W. Chipman, David Giles

Open publisher page 14 citations

Abstract

Late Tertiary silicic ashflow tuffs and lavas peralkaline in chemical character (atomic Na + K greater than Al), mainly comendites, occur over wide areas in northwestern Nevada and appear to be widespread in southeastern Oregon. Such peralkaline rocks-which are not uncommon in the western United States-and other chemically unusual silicic rocks are found near the margins rather than toward the center of the Great Basin.
