Frontiers | Sampling Plants and Malacofauna in 87Sr/86Sr

Establishing strontium isotope (87Sr/86Sr) geographical variability is a key component of any study that seeks to utilize strontium isotopes as tracers of provenance or mobility. Although lithological maps can provide a guideline, estimations of bioavailable 87Sr/86Sr are often necessary, both in qualitative estimates of local strontium isotope …Web

Abstract. Strontium isotopes (87Sr/86Sr) are useful to trace processes in the Earth sciences as well as in forensic, archaeological, palaeontological, and ecological sciences. As very few large-scale Sr isoscapes exist in Australia, we have identified an opportunity to determine 87Sr/86Sr ratios on archived fluvial sediment samples from the …Web

Flood Evidence from Sea Levels and Strontium

The strontium isotope ratios seem to be strongly influenced by the formation of new ocean crust during the Flood, with the lowest ratios corresponding to the maximum volume of seafloor formation. ... In 1989, the average strontium isotope ratio for rivers was estimated to be ~0.712. See Palmer, M. R. and J. M. Edmond. 1989. The …Web

Geochemical characteristics of strontium isotopes in a coastal

Therefore, the strontium isotope ratios in river water should originate from the isotopic values of Sr-bearing minerals in the basin rather than the whole rock types. However, due to lack of isotopic data for regional carbonates and sample sites near carbonate outcrop, the Sr-bearing minerals of regional carbonates was not clear. ...Web
