WebZircon contains the radioactive element uranium, which Dr. Mueller calls “the clock within the zircon” because it converts to the element lead at a specific rate over a long span of time. According to Mueller, this makes zircons “the most reliable natural chronometer that we have when we want to look at the earliest part of Earth history.” WebDec 17, 2024 · Zircon crystal age dating is conducted using the principals of radiometric dating. Basically, all radiometric dating techniques rely on measuring the ratio of two isotopes in a substance: the parent isotope which is radioactive and therefore unstable, and the stable daughter isotope which is the end product of the radioactive decay of the parent.
