Laser-ablation inductively-coupled plasma tandem mass-spectrometry (LA-ICP-MS/MS) allows for rapid and interference free analyses of Rb and Sr isotopes, permitting in situ Rb–Sr dating of minerals. However, the general lack of matrix matched reference materials remains one of its main obstacles, affecting both precision and accuracy. Points are taken from these curves and a plot of fraction Sr-87/Sr-86 (as ordinate) vs. Rb-87/Sr-86 (as abscissa) is made.

Several preconditions must be satisfied before a Rb-Sr date can be considered as representing the time of emplacement or formation of a rock. The system must have remained closed to Rb and Sr diffusion from the time at which the rock formed or fell below the closure temperature i.e the temperature at which a system has Rubidium/Strontium Dating of Meteorites.

This new model for 87 Sr accumulation eliminates the need for either long-term decay of 87 Rb, or the acceleration of 87 Rb decay by many orders of magnitude. When diffusive isotope fractionation of Sr isotopes is repeated a sufficient number of times by within-mantle processes on isotopically-anomalous mantle xenoliths (each of which originally had low 88 Sr/ 86 Sr, high 84 Sr/ 86 Sr, and virtually same equation as for Rb/Sr system Sm-Nd method is useful in Ca-bearing rocks because REE substitute for Ca and garnet (high Sm/Nd ratio) Sm-Nd method relatively resistant to alteration ( 1) 144 147 0 144 143 144 143 + - = e t Nd Nd Sm l 1979-01-01 · The Rb/Sr ratio increases in the metabasalts towards the mineralization (Fig. 5).
