A Novel Approach to Identifying Mantle‐Equilibrated Zircon by Using Trace Element Chemistry
Geochemistry, Geophysics, Geosystems, 2020 One of the requirements for inferring mantle redox states via zircon Ce/Ce* oxybarometry and Ti‐in‐zircon thermometry is to select mantle‐equilibrated zircon derived from melts that have not interacted with the hydrosphere nor assimilated exogenous ...

Does Zircon Shape Retain Petrogenetic Information?
Geochemistry, Geophysics, Geosystems, 2023 Zircon shape is commonly reported during geochronology and geochemistry analyses of igneous, metamorphic, and sedimentary rocks, but the relationship of zircon shape to primary growth environmental conditions remains poorly constrained.

The effect of low-temperature annealing on discordance of U–Pb zircon ages
Scientific Reports, 2021 Discordant U–Pb data of zircon are commonly attributed to Pb loss from domains with variable degree of radiation damage that resulted from α-decay of U and Th, which often complicates the correct age interpretation of the sample.

Improvement of the Thermal Stability of Zircon by Formation of the Solid Solution of Cr in Zircon
Journal of Asian Ceramic Societies, 2020 In this paper, the effects of Cr2O3 additive on the thermal stability and zircon decomposition were investigated. The substitution of Cr at zircon lattice and the formation of solid solution were also discussed. Cr2O3 was added at up to 4 wt.% to zircon.

An X-ray diffraction method for determining the amount of xenotime in a zircon sample [PDF]
Bulletin of the Geological Society of Finland, 1984 An X-ray method was developed for determining the amount of xenotime or zircon in a zircon ‒ xenotime sample. Such analyses are useful in establishing whether a solid solution exists between xenotime and zircon or whether there is a separate xenotime ...
