Radiation damage allows identification of truly inherited zircon
We find that Precambrian zircon found in the Pliocene sample has accumulated substantially more radiation damage than could be explained if they had by Carol Hasenberg Zircon crystals—zirconium silicate to be precise—have become a very important age dating medium for geologists.

Analyses on the zoned zircon crystals with spot analyses 6, 7, and 8 show similar ages for core and rim of ca. 790 Ma. The analyses 4 and 5 in the zoned zircon are also concordant but yield slightly older ages, and display core to rim systematics from 815 to 805 Ma (Online Resource Table S.3).U–Pb zircon geochronology and phase equilibria modelling of HP
