Strategies towards statistically robust interpretations of in situ U–Pb zircon geochronology

open access: yesGeoscience Frontiers, 2016
Zircon U–Pb geochronology has become a keystone tool across Earth science, arguably providing the gold standard in resolving deep geological time. The development of rapid in situ analysis of zircon (via laser ablation and secondary ionization mass ...

Meteoritic Zircon

Science, 1964
Zircon (ZrSiO 5 ) has been identified as an accessory mineral in the Vaca Muerta mesosiderite and in the troilite nodules of the Toluca iron meteorite. The occurrence in Vaca Muerta is a new discovery confirmed by electron-probe microanalysis of a grain in a polished section of the meteorite.

New Magmatic Oxybarometer Using Trace Elements in Zircon

, 2020
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, without explicit determination of the ionic charge of any of them, and ...
