method, known as the Pb-Pb isochron method, is based on a simple extension of
Equation 3.13. By normalizing the quantities 207Pb and 20" Pb in the equation to
the quantity of 204Pb and subtracting the initial amount of Pb, Equation 3.13 ...

Radioactive and Stable Isotope Geology
Recapitulating, any suite of comagmatic rocks with an age f defines an isochron if
its members all had the same initial 87Sr/86Sr ratio and if it was closed to both
Rb and Sr since crystallization occurred and neither element was introduced from
...

CONTENDING FOR THE FAITH: 22 Methodical Arguments for ...
The isochron dating method, while it dispenses with the assumption relating to
initial conditions, must nevertheless incorporate postulations about the rate of
radioactive decay and whether the system was open to external influences.

These two samples also yielded indistinguishable isochron ages of 1.57 ±0.03
Ma and 1.61 ±0.03 Ma respectively (Table 5.6). These ages suggest that Oldeani
activity was of very short duration, lasting for about 90 ka between 1.61 ±0.01 Ma
...
Therefore, samples from these rocks may be employed to obtain an isochron and
hence age. Such an isochron is called the whole-rock isochron. Because the
elemental ratio variation from one rock to another cogenetic rock is small, the ...

This plot is not a standard Rb-Sr isochron plot, and it is not used to determine the
ages of crystallization of igneous plutons. Fleck and Criss also plotted initial Sr
isotope ratios versus Rb/Sr ratios, again not a standard whole-rock isochron plot.
