WebIn order to date co-magmatic igneous rocks by the whole-rock isochron method, a suite of rocks must be collected which span as wide a range of Rb/Sr ratios as possible, so that the slope of the isochron will be well defined. The age of the suite of rocks is obtained from the slope ( m) using the equation m = e λ t− 1.
