Introduction to Sr Isotope Geochemistry | Isobar Science

The element strontium has four naturally occurring isotopes – all are stable: 84 Sr, 86 Sr, 87 Sr, and 88 Sr. Only 87 Sr is radiogenic – produced by the β-decay of 87 Rb with a half-life of 48.8 billion years. The most abundant strontium isotope is 88 Sr, making up

Strontium | Sr - PubChem

Strontium is a naturally occurring element found in rocks, soil, dust, coal, and oil. Naturally occurring strontium is not radioactive and is either referred to as stable strontium or strontium. Strontium in the environment exists in four stable isotopes,84Sr (read as strontium eighty-four),86Sr,87Sr,88Sr. Strontium compounds are used in making ceramics and glass products, pyrotechnics, paint ...

2018-8-10 · Strontium isotope ratio values depend on the isotopic proportions ( 87 Sr to 86 Sr) existing in different geological areas (Copeland et al. 2010 ). The 87 Sr in rock is derived from the decomposition of rubidium ( 87 Rb), and more ancient rocks display higher levels of

Determining landscape use of Holocene mammals using ...

2007-6-26 · The use of the landscape by animals is predicted to be a function of their body size. However, empirical data relating these two variables from an array of body sizes within a single mammalian community are scarce. We tested this prediction by assessing landscape use of mammals by analyzing strontium (Sr) isotope signatures found in mammalian hard tissues representing a 3,000

Problems with Strontium Isotopic Proveniencing in

2021-10-29 · A recent study by Thomsen and Andreasen (2019) has induced a negative reaction to the usefulness of strontium isotope proveniencing. Although there are higher strontium isotope values in the landscape of Denmark, Thomsen and Andreasen are not correct about the impact of this finding on studies of prehistoric mobility. Several case studies identify such “hotspots” in the landscape and help ...
