Tīmeklis2024. gada 1. okt. · 1. Introduction. The 87 Rb– 87 Sr radiogenic isotopic system has been extensively used in geochemistry and cosmochemistry as a powerful geochemical tracer or chronometer since the 1950s [1, 2].High precision ratios of 87 Rb/ 86 Sr and 87 Sr/ 86 Sr are prerequisites for isotope dating and geochemistry tracing purposes. … Tīmeklis2024. gada 6. janv. · The precision of the 87 Sr/ 86 Sr ratio measured using ICP-MS/MS varies between 0.0001 and 0.0019 (2SD). This precision is less than that of the MC-ICP-MS method but is sufficient for certain applications, such as identifying 87 Sr/ 86 Sr ratios in different rock types. TīmeklisThe 87Sr/86Sr ratio is a function of the geochemical origin, Rb concentration, and age of the source rock. Because of the high mass of Sr, the ratio is essentially … raynor firecoil
