The Development of an Analytical Technique to Measure Stable and Radiogenic Strontium Isotope Ratios Using Thermal Ionization Mass Spectrometry with the Double Spike Method
An analytical method using a strontium “double spike” enriched in both 84Sr and 87Sr was developed to measure the n(87Sr)/n(86Sr) and n(88Sr)/n(86Sr) isotope ratios using a thermal ionization mass spectrometer. The results obtained for the SRM987 reference material using this technique are in …

A background investigation into the feasibility of heavy stable isotopes (87Sr/86Sr) as source tracers of early hominids
Heavy stable strontium isotope ratios (⁸⁷Sr/⁸⁶Sr) may be used to characterize the habitat choices of early hominids. The basis for this approach is that different geological substrata may have a characteristic range of ⁸⁷Sr/⁸⁶Sr ratios in the available soil strontium pool. This range may be …

Strontium isotope tracing of prehistoric human mobility in France
… as we go back in time. The application of stable isotopes in archaeological research has revolutionised palaeomobility studies by providing independent data, which can be used to evaluate models of migration, trade, and cultural change. This research project explores the use of strontium isotope …

Fluid relationships in the Northern Gulf of Mexico using dissolved ion concentrations and strontium isotopes
… metal and halogen fluid concentrations and strontium isotope ratios from ten sites on the Gulf of Mexico (GoM) continental slope were compared to identify the variations in chemistry. Geochemical discrepancies are interpreted as coming from chloride sources, fluid mixing and fluid diagenesis …

Regolith and associated mineral systems of the Eucla Basin, South Australia.
… whole rock major, trace element and isotope geochemical data. These data can be combined with other components of the HMS mineral assemblage, together with an understanding of the denudation history of the possible source regions, to establish a landscape evolution model from source, …

Advancements in Isotopic Geolocation Tools for Insect Migration Research
… high abundance, and short lifespans of insects. Isotope geolocation has shown promise for overcoming these obstacles. Here, I develop and apply metals and metal isotopes, specifically strontium isotope ratios (⁸⁷Sr/⁸⁶Sr), to increase the spatial precision of isotope geolocation and demonstrate …
