This requires quantitative determination of the relative proportions of both P and D isotopes, and often requires correction for the inclusion of non-radiogenic D. What makes a Good Geochronometer? All of these systems are based upon the radioactive decay of a parent nuclide to a stable daughter nuclide. Obtaining accurate information from these decay systems for the purposes of determining the age of a mineral or rock requires: In this section we outline the basic principles of the various radio-isotopic geochronometers, differentiating the U-Pb system applied to U-bearing accessory minerals from the isochron geochronometers Re-Os, Lu-Hf, Pb-Pb etc.

The isotopes[ edit ] There are a number of isotopes of interest in U-Pb dating. It has a half-life of 4. It is also useful to know of the existence of Pb lead , which is neither unstable nor radiogenic.
