It's interesting that isochrons depend on chemical fractionation for their validity. Subduction means that these plates are pushed under the continents by motions of the earth's crust. If this is so, the magma would initially be poor in thorium and uranium and rich in lead, and as it cooled it would become rich in thorium and uranium and poor in lead. The problems are compounded because many of the parent and daughter substances are mobile, to some extent. Over a thousand papers on radiometric dating were published in scientifically recognized journals in the last year, and hundreds of thousands of dates have been published in the last 50 years. Then from mixing, one can produce an isochron having a spurious age. Also, it is reasonable to assume that as argon leaves the mantle in successive eruptions, the amount of argon remaining is reduced, so that later lava flows are less susceptible to such artificial increases in age. Therefore, my main concern is with rocks of the Cambrian periods and later. Dickin Radiogenic Isotope Geology, , p. Coffin mentions that fission tracks can survive transport through lava, for example.

    But this cannot explain the distribution of lead isotopes. Also, they do not get quickly buried by additional sediment.

    A few sources have said that Sr is mobile in rock to some extent.

    Also, they do not get quickly buried by additional sediment. This would probably have a larger effect lower down, where the pressure of argon would be higher.

    The only correlation I know about that has been studied is between K-Ar and Rb-Sr dating on precambrian rock. The condition that one of the sources have no P, D, or N is fairly natural, I think, because of the various fractionations that can produce very different kinds of magma, and because of crustal materials of various kinds melting and entering the magma.

    Suppose P p is the concentration of parent at a point p in a rock. Due to the fact that we know nothing of radiometric decay rates all through history, nor what is called Deep Time by old agers.
