strontium isotope soil

ESSD - Bioavailable soil and rock strontium isotope data ...

Strontium isotope ratios (87 Sr ∕ 86 Sr) of biogenic material such as bones and teeth reflect the local sources of strontium ingested as food and drink during their formation. This has led to the use of strontium isotope ratios as a geochemical tracer in a wide range of fields including archaeology, ecology, food studies and forensic sciences.

A strontium isotope baseline of Cyprus. Assessing the use ...

2020-03-15  Strontium is a trace element with four naturally occurring isotopes, namely 84 Sr, 86 Sr, 88 Sr and 87 Sr, of which the first three are stable and the last, 87 Sr, is radiogenically generated from the decay of 87 Rb. The 87 Sr/ 86 Sr ratio varies between bedrocks, dependent on the age and type of the rocks (Banner, 2004, Capo et al., 1998).

Introduction to Sr Isotope Geochemistry Isobar Science

The element strontium has four naturally occurring isotopes – all are stable: 84Sr, 86Sr, 87Sr, and 88Sr. Only 87Sr is radiogenic – produced by the β-decay of 87Rb with a half-life of 48.8 billion years.

Strontium isotope ratio determination in soil and bone ...

In this work we investigate strontium isotopic ratios in human skeletal remains and reference soil samples from the corresponding archaeological sites. Because 87 Sr is spectrally overlapped by 87 Rb (m /Δ m = 300.000), a separation prior to analysis was a prerequisite for accurate isotope ratio determination especially in soil samples.

2016-11-01  The (87)Sr/(86)Sr isotope ratios were measured on grape, wine and soil samples collected in 13 commercial vineyards located in three major wine producing areas of Quebec (Canada). The soils yield Sr isotope ratios that are intimately related to the local geology and unambiguously discriminate the different producing areas. A strong relationship exists between the (87)Sr/(86)Sr isotope ratios ...

Fixation of Radioactive Strontium in Soil — DTU Research ...

Of special importance is the long-lived strontium-90, as it has been shown1 that this isotope is taken up by plants to a much greater extent than any of the other long-lived fission products. Much work2–5 has, therefore, been concerned with the possibility of bringing down the strontium-90 uptake by plants through ploughing or through the addition of lime or fertilizer to the soil. Another ...

USGS -- Isotope Tracers -- Resources

Periodic Table--Strontium. The alkali earth metal strontium has four stable, naturally occurring isotopes: 84 Sr (0.56%), 86 Sr (9.86%), 81 Sr (7.0%) and 88 Sr (82.58%). Only 87 Sr is radiogenic; it is produced by decay from the radioactive alkali metal 87 Rb, which has a half-life of 48,800,000 years. Thus, there are two sources of 87 Sr in any material: that formed during primordial nucleo ...

Strontium isotopes ((87)Sr/(86)Sr) can be useful biological markers for a wide range of forensic science applications, including wildlife tracking. However, one of the main advantages of using (87)Sr/(86)Sr values, that there is no fractionation from geological bedrock sources through the food web, also happens to be a critical assumption that has never been tested experimentally. We test this ...

Strontium isotope ratios (87Sr/86Sr) in bulk-CUB samples (total dissolution of CUB) are generally higher in class F ash than in class C ash. Bulk-CUB ratios appear to be controlled by the geologic source of the mineral matter in the feed coal, and by Sr added during desulfurization treatments. Leachates of the CUB generally have Sr isotope ratios that are diff erent than the bulk value ...

The most common method in archaeological strontium isotope literature [9,14,22,24,31–36] to differentiate local (presumably philopatric) and non-local (dispersing) individuals is to first, use botanical, soil or micromammal samples to define minimum and maximum strontium isotope ratios for a predefined local site, such as discrete geologic formations, site associations or community ...
