Faure, 1972). The isotopic composition of strontium dissolved in sea water has also attracted considerable attention, because it is believed to reflect the Rb-enrichment and age of the rocks which are exposed to weathering on the continents and in the ocean basins (Faure, et al., 1965). A large number of isotope analyses of strontium in

Isotopes. Natural strontium is a mixture of four stable isotopes: 84 Sr, 86 Sr, 87 Sr, and 88 Sr. Their abundance increases with increasing mass number and the heaviest, 88 Sr, makes up about 82.6% of all natural strontium, though the abundance varies due to the production of radiogenic 87 Sr as the daughter of long-lived beta-decaying 87 Rb.

Strontium Isotope Geology | G. Faure | Springer

Strontium-90 (90Sr) is a radioactive isotope of strontium produced by nuclear fission, with a half-life of 28.8 years. It undergoes β− decay into yttrium-90, with a decay energy of 0.546 MeV. Strontium-90 has applications in medicine and industry and is an isotope of concern in fallout from nuclear weapons and nuclear accidents.

Uses of Strontium Isotopes in Petrogenesis | SpringerLink

Because strontium has an electron configuration similar to that of calcium, it readily substitutes for Ca in minerals. In addition to the four stable isotopes, thirty-one unstable isotopes of strontium are known to exist (see Table, below): the longest-lived of these are 90 Sr with a half-life of 28.9 years and 85 Sr

Strontium isotope ratios ( 87 Sr/ 86 Sr) depend primarily on Rb/Sr initial ratios of rocks and their ages (e.g., Faure, 1986; Faure and Powell, 1972) because radiogenic Sr isotopes ( 87 Sr/ 86 Sr ...

Journal of Archaeological Science - Mount Mercy University

The strontium isotope ratios in different rocks are a direct function of the age and composition of the material (Faure 1986; Faure and Powell 1972). Because materials in nature have variable strontium contents, variations in absolute 87Sr abundances are expressed as isotope ratios. Variations in strontium

Strontium in the brines of Great Salt Lake appears to be isotopically homogeneous and has an average 87 Sr/ 86 Sr ratio of 0.7174 ± 0.0004 (1σ). The enrichment in radiogenic 87 Sr compared to young volcanic rocks and modern sea water is consistent with the 87 Sr/ 86 Sr ratios in water from its major tributary rivers which drain the Wasatch Mountains east and southeast of the lake.
