Groundwater discharge impacts marine isotope budgets of Li, Mg, Ca, Sr, and Ba
Nature Communications, 2021 Groundwater-derived solute fluxes to the ocean have long been assumed static and subordinate to riverine fluxes, if not neglected entirely, in marine isotope budgets.

Radioactive Isotopes of Sr, Y and Zr [PDF]
Physical Review, 1940 Radioactive isotopes formed by bombardment of Rb, Sr and Y by protons, deuterons and neutrons are reported. The following are the periods and assignments: 2.75-hr. (Sr87*, e-, γ); 70-min. (Sr85, e-, γ); 66-day (Sr85, K, γ); 80-hr. (Y87, K); 14-hr. (Y87, e-, γ); 105-day (Y86, K, γ); 4.5-min. (Zr89, γ); 78-hr. (Zr89, β+).

Specificity and Origin of the Stability of the Sr Isotopic Ratio in Champagne Wines [PDF]
Molecules, 2021 The 87Sr/86Sr ratio of 39 Champagnes from six different brands, originating from the whole “Appellation d’Origine Contrôlée” (AOC) Champagne was analyzed to establish a possible relation with the geographical origin. Musts (i.e., grape juice) and base wines were also analyzed to study the evolution of the Sr isotopic ratio during the elaboration ...

A database of radiogenic Sr–Nd isotopes at the “three poles”
Earth System Science Data, 2022 Abstract. The radiogenic isotope compositions of strontium (Sr) and neodymium (Nd) on the surface of the Earth are powerful tools for tracing dust sources and sinks on the Earth's surface. To differentiate between the spatial variabilities in eolian dust sources in key cryospheric regions at the three poles (the Arctic; Antarctica; and the “third pole”,

Potential use of Sr isotope ratio to evaluate trace metal uptake in moss
Ecological Indicators, 2021 Moss biomonitoring is widely applied to evaluate trace metals in atmospheric deposition and can be especially useful in mountainous areas where the installation and maintenance of physical equipment are often challenging.

Ca and Sr isotope constraints on the formation of the Marinoan cap dolostones
Earth and Planetary Science Letters, 2019 Neoproterozoic cap dolostones, which ubiquitously overlie Marinoan glacial diamictites, may record marine and climatic paleo-environmental conditions at the termination of the largest glacial epoch in Earth's history.

Resolving archaeological populations with Sr-isotope mixing models [PDF]
Applied Geochemistry, 2007 Strontium isotope analysis of tooth enamel is a useful provenancing technique to investigate the childhood origins and residential mobility of ancient people. However, where different geographical target regions have similar biosphere 87Sr/86Sr it is often difficult to resolve the 87Sr/86Sr ranges of two different groups of people and establish what ...
