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 …

Potentially biogenic carbon preserved in a 4.1 billion-year-old zircon
Evidence of life on Earth is manifestly preserved in the rock record. However, the microfossil
record only extends to∼ 3.5 billion years (Ga), the chemofossil record arguably to∼ 3.8 Ga …
