Abstract. The 87 Sr/ 86 Sr ratio in fish teeth separated from mid-Cretaceous marl and black shale from the northeastern Apennines and Venetian Alps (Italy) define three periods of low 87 Sr/ 86 Sr ratio at 121 to 124 million years ago (Ma), 110 to 115 Ma, and 89 to 91 Ma. The 87 Sr/ 86 Sr excursions correspond to oceanic anoxic events ...

Strontium and Lead isotopes in forensic geography | Isobar Science
Strontium isotopes ( 87 Sr/ 86 Sr) provide a fingerprint of the source of food consumed during an individual's lifetime, as these isotopes are abundant in water and bedrock and are eventually integrated into soil and plants (Pye et al. 2004; Bartelink et al. 2019). Additionally, oxygen isotopes ( 𝛿18 O) can be analysed to pinpoint water ...

Characteristics of geothermal waters in eastern
The dissolved strontium isotope composition is influenced by the minerals in the reservoir, not by mineral precipitation or cation exchange in the evolution of groundwater circulation (Bullen et al., 1996). Thus, the strontium isotope can be used to examine the geothermal circulation pathway (Fan et al., 2018).

Abstract. The isotopic ratio of strontium-87 to strontium-86 shows no detectable variation in present-day ocean water but changes slowly over millions of years. The strontium contained in carbonate shells of marine organisms records the ratio of strontium-87 to strontium-86 of the oceans at the time that the shells form.
