Schematic illustration of the effect of different common Pb compositions on the isochron defined by data uncorrected for common Pb on a a Tera-Wasserburg and b Wetherill concordia diagram. Isochrons through a hypothetical array of data with the same age but a range of Pb*/PbC are shown. For each plot, two isochrons with the same crystallization age but different common Pb compositions are shown. a On the Tera-Wasserburg concordia, the common Pb composition is given by the y-intercept of the isochron, while b on the Wetherill, it is the slope of the isochron that relates to the common Pb composition.
