The biogeochemical cycling of metals in natural systems is often accompanied by stable
isotope fractionation which can now be measured due to recent analytical advances. In …

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

The global climate of the Ordovician Period (486.9 to 443.1 Ma) is characterized by cooling
that culminated in the Hirnantian glaciation. Chemical weathering of Ca-and Mg-bearing …

This paper critically reviews the state-of-the-art of isotope amount ratio measurements by
solution-based multi-collector inductively coupled plasma mass spectrometry (MC ICP-MS) …

Abstract Radiogenic Sr isotopes (87 Sr/86 Sr) are robust for provenance identification in
hydrology, affected mainly by the age of background lithologies and the degree of chemical …

At Earth's surface the stable isotope ratio of strontium (88Sr/86Sr) is predominantly set by
biological uptake of Sr and its storage in plant litter. This conclusion was reached from a …

The mineral barite (BaSO 4) accommodates strontium (Sr) in its crystal structure, providing
an archive of Sr-isotopes (87 Sr/86 Sr and δ 88/86 Sr) in the highly stable sulfate mineral …

This paper presents a detailed review of the use of 87Sr/86Sr isotope systematics for wine
provenance studies. The method is based on the principle that the Sr isotope ratio in wine …

Mineralization at the supergiant Cu-U-Au-Ag Olympic Dam deposit (South Australia), the
'uranium endmember'of the iron-oxide copper–gold (IOCG) spectrum of ore deposits, is …

Drinking water is scarce in Djibouti because of the hot desert climate. Moreover, seawater
intrusion or fossil saltwater contamination of the limited number of freshwater aquifers due to …
