Radiometric datingradioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbonin which trace radioactive impurities were selectively incorporated when they were formed. Radioactive material gets a bad rap, what with radiation and fallout and nuclear waste and all. When we speak of the element Carbon, we most often refer to the most naturally abundant stable isotope 12 C. You've got two decay products, lead and helium, and they're giving two different ages for the zircon. This page has been archived and is no longer updated.
When a rock cools from the molten to the solid state, its radioactive isotopes are immobilized in mineral crystal lattices and then decay in place.
