Abstract
In recent stratigraphic studies of Tertiary ignimbrites in the Great Basin, correlation of units by distinctive lithologic features is independently verified by quantitative study of phenocrysts. The relative abundance of 6 mineral groups can be readily evaluated by area counts, with a binocular microscope, of etched and stained rock slices. The method obtains results rapidly and with sufficient accuracy to confirm field correlations, as is demonstrated by phenocryst study of 4 tuffs comprising the Quichapa formation.
