The effect of low-temperature annealing on discordance of U–Pb zircon ages [PDF]
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.

Genesis of zircon and its constraints on interpretation of U-Pb age
Science Bulletin, 2004 Zircon U-Pb dating is the most commonly used method for isotopic geochronology. However, it has been a difficult issue when relating zircon U-Pb ages to metamorphic conditions in complex metamorphic rocks. Much progress has been made in the past decade with respect to the genesis of zircon and its constraints on interpretation of U-Pb age.
