Strontium isotopes as tracers of ecosystem processes

1998-2-1  Strontium isotopes can be a powerful tool in ecosystem studies, both as a tracer of nutrient sources and as a monitor of the weathering process. In many cases, isotopic characterization of sources to an ecosystem allows quantification of the relative contributions of in situ weathering and atmospheric inputs to soil and vegetation.

Strontium isotopes as tracers of ecosystem processes

Strontium isotopes can be used to track the biogeochemical cycling of nutrient cations such as calcium. The extent of cation contributions from in situ weathering and external additions to soil from dust and rain can also be resolved with this method.

Strontium Isotope Analysis « Center for Applied

Strontium isotopic ratios are widely used as tracers in geological processes and as indicators of provenance in an archaeological context. A significant fraction of the Earth’s 87 Sr is not primordial, but is produced by the decay of 87 Rb. Geochemically, Strontium follows Calcium, while Rubidium follows Potassium; thus, the geological variability of Sr isotope ratios in rocks is a function of both their age

2018-12-1  Sr isotopes (87 Sr/ 86 Sr) ratio as an indicator of weathering processes and secondary mineral precipitation/dissolution. In various ecosystems, the Sr sources mainly represent a mixture of atmospheric input and mineral weathering ( Graustein and Armstrong, 1983 ; Gosz et al., 1983 ; Åberg et al., 1989 ; Graustein, 1989 ).

Isotopes of Strontium: Properties and Applications

2019-6-5  Natural strontium consists of the following four stable isotopes: 84 Sr (0.56%), 86 Sr (9.86%), 87 Sr (7.00%), and 88 Sr (82.58%). Among them, 87 Sr is a radiogenic isotope being the decay product of the long-lived natural beta-emitting isotope 87 Rb; it is widely used in geology for rocks and minerals dating as well as for systematization of origin of various rock formations.

2016-7-1  The combination of stable and radiogenic strontium isotopes applied to weathering processes shows that radiogenic Sr isotopes provide information regarding incongruent weathering of primary phases. By contrast, stable Sr isotope variations most likely reflect the formation of secondary weathering minerals, which incorporate the light isotopes, driving the DL to heavier values and the SS to lighter.

Strontium has four naturally occurring stable isotopes; variations in the relative proportions of Sr isotopes (expressed as the ratio of 87-strontium to 86-strontium, or 87 Sr / 86 Sr) are due to the formation of radiogenic 87 Sr from the natural rr decay of 87 Rb (half-life = 48.8 Ga). vermiculite, smectite).

Using strontium isotopes to study site accumulation

Strontium isotopes (87Sr/86Sr) in tooth enamel reflect the geological substrate on which an animal lived during tooth development. Therefore, strontium isotopes of teeth in fossil cave accumulations are potentially useful in determining whether an animal was native to the vicinity of the site or was brought in by other agents such as predators from farther afield.
