The Provenance of Slovenian Milk Using 87Sr/86Sr Isotope Ratios [PDF]

open access: yesFoods, 2021
This work presents the first use of Sr isotope ratios for determining the provenance of bovine milk from different regions of Slovenia. The analytical protocol for the determination of 87Sr/86Sr isotope ratio was optimised and applied to authentic milk ...

Fine-Scale Strontium Isotope Mapping in Eastern China (Anhui Province) and Its Application in Food Traceability [PDF]

open access: yesFoods
Origin traceability is critical for food safety, and the strontium isotope ratio (87Sr/86Sr) has been widely used in this field due to its accuracy and stability.

The Giant Pacific Oyster (Crassostrea gigas) as a modern analog for fossil ostreoids: Isotopic (Ca, O, C) and elemental (Mg/Ca, Sr/Ca, Mn/Ca) proxies [PDF]

open access: yesGeochemistry, Geophysics, Geosystems, 2013
Modern analogs are an essential part of palaeoclimate studies, because they provide the basis for the understanding of geochemical signatures of fossils.

Random forest-based bioavailable strontium isoscape for environmental and archaeological applications in central eastern Argentina and western Uruguay. [PDF]

open access: yesPLoS ONE
Bioavailable strontium (Sr) isoscapes are essential tools in studies on environmental processes, animal and human mobility and provenance. The success of these studies relies on the comparison between the measured 87Sr/86Sr isotope ratios of specimens ...

Sensitivity assessment of strontium isotope as indicator of polluted groundwater for hydraulic fracturing flowback fluids produced in the Dameigou Shale of Qaidam Basin

open access: yesJournal of Groundwater Science and Engineering, 2021
Hydrogeochemical processes that would occur in polluted groundwater and aquifer system, may reduce the sensitivity of Sr isotope being the indicator of hydraulic fracturing flowback fluids (HFFF) in groundwater.

Stable Sr isotope (88Sr/86Sr) fractionation in calcite precious corals

open access: yesFrontiers in Marine Science, 2022
Stable isotope ratios of Sr (88Sr/86Sr) are a novel indicator for identifying terrestrial and oceanic Sr cycling and biological processes. Here we evaluate the temperature dependence of stable Sr isotope ratios (δ88Sr) in the calcite skeletons of ...

High Precision Strontium Isotope Measurement of Rock Standard Materials by Multi-dynamic TIMS

open access: yesYankuang ceshi, 2023
BACKGROUNDStrontium isotopes are a powerful geochemical indicator for tracing the sources and ages of ore-forming materials. TIMS is internationally recognized as the “gold standard” for determining Sr isotopic compositions, however, its analysis ...

Distribution of s-, r-, and p-process Nuclides in the Early Solar System Inferred from Sr Isotope Anomalies in Meteorites

open access: yesThe Astrophysical Journal Letters, 2023
Nucleosynthetic isotope anomalies in meteorites allow distinguishing between the noncarbonaceous (NC) and carbonaceous (CC) meteorite reservoirs and show that correlated isotope anomalies exist in both reservoirs.

The Capitanian Minimum: A Unique Sr Isotope Beacon of the Latest Paleozoic Seawater

open access: yesFrontiers in Earth Science, 2021
The long-term trend in the Paleozoic seawater 87Sr/86Sr was punctuated by a unique episode called the “Capitanian minimum” at the end of the Guadalupian (Permian; ca. 260 Ma).

Strontium Isotope Systematics of Tenerife Wines (Canary Islands): Tracing Provenance in Ocean Island Terroir

open access: yesBeverages, 2022
The production of fraudulent goods remains widespread and economically damaging. The high value of the wine industry makes it particularly vulnerable, and a number of geochemical methods have been developed to ensure traceability and identification of ...
