The Pb-Pb isochron dating method may, in many cases, yield reliable ages for weathered samples from areas where other techniques are inappropriate because of the separation of parent and daughter isotopes as the result of weathering. Four Australian case histories illustrate the potential and problems of applying the technique in Archaean and Proterozoic terrains. By comparison with other techniques that may be applied to weathered rocks, such as the zircon U-Pb method, the Pb-Pb technique is rapid, and field sampling and sample preparation are simple and inexpensive.
