| Abstract: | Despite Oversby's 1] belief, the I,S] diagram 2] is as much sensitive as the α, β] diagram since both of them are based on the same isotopic evolution equations. Also, we do insist again on the greater simplicity of the I,S] diagram in process in Pb-Pb data for whole rock series to study global isotopic evolution, and most particularly in the case where initial isotopic composition for the series considered cannot be measured. |
