Insight into zircon REE oxy-barometers: A lattice strain model perspective
Zircon rare earth element (REE) oxy-barometers have been widely used to calculate magma
oxygen fugacity. However, sometimes confusing results are obtained, such as extremely …

The crustal architecture of Myanmar imaged through zircon U-Pb, Lu-Hf and O isotopes: Tectonic and metallogenic implications
The Tethys margin in central and eastern Asia is comprised of continental terranes
separated by suture zones, some of which remain cryptic. Determining the crustal …

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
EA Bell, P Boehnke, TM Harrison… - Proceedings of the …, 2015 - National Acad Sciences
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 …

Qinghu zircon: A working reference for microbeam analysis of U-Pb age and Hf and O isotopes
Zircon is the most useful mineral for studies in U-Pb geochronology and Hf and O isotope
geochemistry. Matrix effect is a major problem of the microbeam techniques such as SIMS …

Reappraisement and refinement of zircon U-Pb isotope and trace element analyses by LA-ICP-MS
A protocol was established for simultaneous measurements of zircon U-Pb ages and trace
elements by LA-ICP-MS at spot sizes of 16–32 μm. This was accomplished by introducing …
