In the laboratory, rock samples are crushed and the zircon grains are separated from the other minerals by heavy liquid and other mineral separation techniques. Detrital zircon geochronology is the science of analyzing the age of zircons deposited within a It has become increasingly popular in geological studies from the s mainly due to the advancement in radiometric dating techniques. Zircon crystals grow between and °C, while lead is retained within the crystal. Detrital zircon geochronology is the science of analyzing the age of zircons deposited within a specific sedimentary unit by examining their inherent radioisotopesmost commonly the uranium—lead ratio.

Zircon Crystals trap Uranium Atoms in its crystal structure and naturally repel Lead Atoms when the crystal forms. The two decay chains used on zircon dating are the uranium series and the actinium Uranium decay traps lead atoms in the crystal; these atoms get more. Radiometric dating is a much misunderstood phenomenon.
