New magmatic oxybarometer using trace elements in zircon
RR Loucks, ML Fiorentini, GJ Henríquez - Journal of Petrology, 2020 - academic.oup.com
We derive a novel method for determining the oxidation state of a magma as zircon
crystallized, with a standard error of±0· 6 log unit ƒO2, using ratios of Ce, U, and Ti in zircon …
