Enormous volumes of low - δ18O rhyolite in the Central Snake River Plain, Idaho
Oxygen isotope analyses illustrate interactions between surface waters and magmas. That is because the earth’s only low-δ18O reservoir is meteoric water – water from rain and snow. This talk will give a crash course in oxygen isotopes, describe the unusual physical features of Snake River Plain rhyolites, and compare the two current models for the formation of low-δ18O rhyolites along the Yellowstone Hotspot track.
