Analysis of strontium isotopes reveals new insight into who built Stonehenge. 24 July 2018. Results of a School led, collaborative study published in Nature Scientific Reports this week emphasise the importance of inter-regional connections involving the movement of both materials and people in the construction and use of Stonehenge. The study combined radiocarbon-dating with new developments ...

We are very thankful to Tom Bullen for constructive input and insight to the first iterations of this manuscript. Additionally, the helpful and constructive reviews from Clement Bataille and the anonymous reviewer that greatly helped shape and focus the discussion and ...

Finally, Sr isotopes are not measurably fractionated by geological processes, unlike the isotopes of the light elements. All these characteristics potentially make Sr a good tracer of the source rock(s) of the chemical constituents in water. The isotopic value provides an added insight to that achieved by analysing elemental abundances, and this is especially the case when there is ...

Strontium Isotope Analysis « Center for Applied Isotope ...

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 ...

25/03/2021  New analysis of strontium isotopes reveals how the global carbon cycle has responded to changes in climate and sea level through geologic time. A new analysis of strontium isotopes in marine sediments has enabled scientists to reconstruct fluctuations in ocean chemistry related to changing climate conditions over the past 35 million years. The results, published on March 26, 2021, in the ...

Immigrants and interactions at Cahokia: insights from ...

In this study, strontium and carbon isotope data derived from tooth enamel from individuals buried within Cahokia’s Mound 72 provide direct evidence for diet and place of origin for this ritually and politically important site. We present a suite of preliminary isotopic data for burials within SubMd1 of Mound 72, including Feature 101, the ‘Beaded Cape’ burial feature, and ‘Retainer ...

While the Welsh connection was known for the stones, the study shows that people were also moving between west Wales and Wessex in the Late Neolithic, and that some of their remains were buried at ...

Isotopes of strontium - Wikipedia

The alkaline earth metal strontium (38 Sr) has four stable, naturally occurring isotopes: 84 Sr (0.56%), 86 Sr (9.86%), 87 Sr (7.0%) and 88 Sr (82.58%). Its standard atomic weight is 87.62(1).. Only 87 Sr is radiogenic; it is produced by decay from the radioactive alkali metal 87 Rb, which has a half-life of 4.88 × 10 10 years (i.e. more than three times longer than the current age of the ...

Ancient DNA, Strontium isotopes, and osteological

17/11/2008  Strontium isotope analyses point to different origins for males and children versus females. By this approach, we gain insight into a Late Stone Age society, which appears to have been exogamous and patrilocal, and in which genetic kinship seems to be a focal point of social organization. In 2005 four outstanding multiple burials were discovered near Eulau, Germany. The 4,600-year-old

The lagoon hydrology is controlled by seawater-continental water mixing processes that are traceable via the radiogenic Strontium (Sr) isotopes (87 Sr/ 86 Sr ratios). The hypersaline South Lagoon, being more geomorphologically restricted, is known for high degree of evaporation, which leads to ongoing calcium carbonate precipitation, which also acts as a sink for dissolved inorganic carbon ...

06/08/2018  In essence, strontium isotope ratios are signatures of different rock types. The food chain moves these atoms into the human skeleton from bedrock through water, soils, plants, and herbivores. Because human tooth enamel does not change after formation, it provides a stored signal of the strontium isotopes of the place of birth. If the strontium ...
