Melt inclusion and mineral geochemical analyses supporting the evaluation of petrogenesis, degassing, and metallogenic potential of mid-Cenozoic rhyolite magmas in northern Nevada, USA

This data release presents geochemical analyses of silicate melt inclusions, host quartz phenocrysts, and biotite phenocrysts in samples collected by the U.S. Geological Survey (USGS) from mid-Cenozoic rhyolitic rocks from northern Nevada. Igneous intrusions and volcanic rocks in this study encompass nineteen rhyolitic samples from five magmatic centers across northeastern Nevada. Rhyolites were emplaced throughout northeastern Nevada over about an 8 million year timespan (41–33 mega-annum) in a variety of eruptive styles and volumes, ranging from meter-wide dikes to caldera-forming ignimbrites, and were roughly contemporaneous with regional ore deposition. Samples were prepared for petrographic and scanning electron...
