    The Isochron methods makes the assumption that at time zero, the ratio
    between the measured isotopes is 0 (or, in other word, they are
    homogeneously mixed throughout the magma). This ratio makes a horizontal
    line across the chart and this is the reference point from which one
    compares the slope of an isochron line. The problem is, no one was there to
    see if the ratio between the isotopes was really zero (i.e. if they were
    homogenous). Thus, this method is no better than any other method. One has
    to assume a zero slope at time zero. But, no one knows for sure and they
    cannot know for sure. The more I read of the mix of magma, the more I read
    of it being non-homogenous in any way.

    The original mix of measured isotopes may have been at slope 1 and the
    current reading may be at slope 1.005. The actual time lapse would be the
    difference between slope 1 and slope 1.005 (= 0.005) not between slope 0
    and 1.005.

    All radiometric methods depend upon assumptions which are falsified or
    unknowable.
