All that is required is for radioactive lead solutions to flow by and coat inactive lead. We all seem to have this image in our mind of the various dating methods agreeing with each other and also with the accepted age of their geologic periods.
It employs is isotope worst we We of so. Gill's simple linear regressions are not the exact the technique used to radiogenic dating isochron fits. Usually the concentration of uranium and thorium varies in different places in rock.

And yet we expect that uranium-lead ratios are determined by radiometeric decay alone or at least sometimes! Faure discusses fractional crystallization relating to U and Th in his book p.
This is unacceptably high for current theories of lunar origins and disagrees with measurements made on other moon materials. This could produce an arbitrary isochron, so this mixing could not be detected. At first, the use of "key" diagnostic fossils was used to compare different areas of the geologic column.
They are independent of each other, but will be concordant that is, agree with each other if the mineral samples satisfy the conditions for dating Faure and Mensing— Or maybe the uranium poor rocks crystallize out first and the remaining magma is enriched in uranium.
