The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Geophysical Monograph Series, Page 229-246., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Frontiers in Ecology and Evolution, 2023 Anthropogenic activities are exposing insects to elevated levels of toxic metals and are altering the bioavailability of essential metals. Metals and metal isotopes have also become promising tools for the geolocation of migratory insects.

Ecosphere, 2021 Understanding seasonal mobility, population connectivity, and site fidelity is critical for managing and preserving migratory species. We investigated the potential of coupling strontium (87Sr/86Sr) and hydrogen (δ2H) isotopes in feathers for ...

Strontium Isotope as Tracers of Groundwater Contamination [PDF]
, 2017 Groundwater flowing under a municipal solid waste landfill has been studied to identify potential contamination phenomenon and to test strontium isotopic composition as a natural tracer of contamination.

Yankuang ceshi, 2019 BACKGROUND The traceability study of uranium ore concentrates plays an important role in nuclear forensics. By measuring the abundance ratios of lead and stontium isotopes, the results can provide some geographical indication information for traceability.

Chemostratigraphy of Neoproterozoic carbonates: implications for 'blind dating' [PDF]
, 2001 The delta C-13(carb) and Sr-87/Sr-86 secular variations in Neoproteozoic seawater have been used for the purpose of 'isotope stratigraphy' but there are a number of problems that can preclude its routine use.

A score of bioavailable strontium isotope archaeology in China: Retrospective and prospective
Frontiers in Earth Science, 2023 Bioavailable strontium isotope analysis was proposed for prehistoric human ecology almost 40 years ago and rapidly became one of the most important tools to trace past migratory behaviours.

Mass scaling and non-adiabatic effects in photoassociation spectroscopy of ultracold strontium atoms [PDF]
, 2014 We report photoassociation spectroscopy of ultracold $^{86}$Sr atoms near the intercombination line and provide theoretical models to describe the obtained bound state energies. We show that using only the molecular states correlating with the $^1S_0$$+$$

Geophysical Research Letters, 2023 In the southwest Japan forearc, slab‐fluids produced from subducted materials migrate to crustal levels and appear as deep‐seated brine. We have analyzed for the first‐time stable strontium isotopes in non‐volcanic spring water with high salinity ...
