The reason for stopping at lead is because lead is not radioactive and will not change into a different element.

The plot of the ratios will then produce a straight line below the Concordia curve.

Uranium-Lead dating is a radiometric dating method that uses the decay chain of uranium and lead to find the age of a rock.

– A new study by geologists at the Berkeley Geochronology Center and the University of California, Berkeley, improves upon a widely used dating technique, opening the possibility of a vastly more accurate time scale for major geologic events in Earth's history.

In a paper published this week in Science, geochemist Roland Mundil of the Berkeley Geochronology Center (BGC) and his colleagues at BGC and UC Berkeley report that uranium/lead (U/Pb) dating can be extremely accurate - to within 250,000 years - but only if the zircons from volcanic ash used in the analysis are specially treated.
