Recent developments and trends in the application of strontium and its isotopes in biological related fields [PDF]

, 2017
Strontium is a chemical element without biological functions in humans. In fact, only two biological roles are known, both as a biomineral constituent.

Strontium isotope and element constraints on the paleoenvironment of the latest Ediacaran in the Sichuan Basin, southeastern Tibetan Plateau

Frontiers in Earth Science, 2022
The Ediacaran–Cambrian period witnessed episodic extinctions, oxygenation of seawaters, Cambrian explosions, and tectonic events. However, compared with the various high-resolution geochemical records of the early–middle Ediacaran and Cambrian, the ...

Sr-isotope analysis of speleothems by LA-MC-ICP-MS: High temporal resolution and fast data acquisition [PDF]

, 2017
Speleothems are well established climate archives. A wide array of geochemical proxies, including stable isotopes and trace elements are present within speleothems to reconstruct past climate variability.

⁸⁷Sr/⁸⁶Sr Isotope Ratio as a Tool in Archaeological Investigation: Limits and Risks

Quaternary
During the last forty years, the use of strontium isotopes in archaeology and biogeochemical research has spread widely. These isotopes, alone or in combination with others, can contribute to trace past and present environmental conditions.

Strontium isotopes in Early Jurassic seawater

Geochimica et Cosmochimica Acta, 1994
Abstract The analysis of well-preserved, well-dated belemnites and oysters from the Jurassic of Great Britain has resulted in a well-constrained, detailed seawater strontium isotope curve for the Early Jurassic. The preservation of fossil low-Mg calcite was monitored using Mn, Fe, δ 13 C , and δ 18 O .
