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.

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 ...

The Medicine Hat Block and the Early Paleoproterozoic Assembly of Western Laurentia
Geosciences, 2020 The accretion of the Wyoming, Hearne, and Superior Provinces to form the Archean core of western Laurentia occurred rapidly in the Paleoproterozoic. Missing from Hoffman’s (1988) original rapid aggregation model was the Medicine Hat block (MHB).
