Tīmeklis2015. gada 2. nov. · The combination of laser ablation and tandem ICP-mass spectrometry (LA-ICP-MS/MS) allows for successful Sr isotopic analysis of solid samples with high Rb/Sr ratios. Isobaric overlap at a mass-to-charge ratio of 87 (87Sr–87Rb) is overcome via chemical resolution. By using CH3F/He (10% CH3F in … http://web.mit.edu/wangfire/pub8.14/oppaper.pdf

If the initial amount of Sr is known or can be extrapolated, the age can be determined by measurement of the Rb and Sr concentrations and the 87 Sr/ 86 Sr ratio. The dates indicate the true age of the minerals only if the rocks have not been subsequently altered.
