Isotopic and Geochemical Signatures of Mantle and Crustal Contributions in Rhyolites from Okataina and Taupo volcanoes, New Zealand

The data here was collected at Oregon State University (major and trace elements) and New Mexico State University in order to address rhyolite petrogenesis in the Taupo Volcanic Zone (TVZ), New Zealand. Each sheet contains data for 18 eruptions from Okataina and Taupo Volcanic Centers, the two most recently active centers in the TVZ. Major element concentrations, trace element concentrations, and Pb and Sr isotopic compositions were collected for each eruption and are tabulated in individual sheets, along with standard measurements for each technique. Major and trace elements were measured in pumice glass fragments (each on the same fragments), while isotopic compositions were measured in dissolved pumice powder from the same sub-samples as the in-situ techniques. The dataset also includes a suite of previously published isotopic data for comparative purposes.
