At the Earth's surface, calcium (Ca) is a critical element at a variety of scales: it is soluble in
natural waters, a biological nutrient, and a major constituent of the dominant mineral sink for …

This work critically reviews stable isotope fractionation of essential (B, Mg, K, Ca, Fe, Ni, Cu,
Zn, Mo), beneficial (Si), and non-essential (Cd, Tl) metals and metalloids in plants. The …

Shallow-water carbonate sediments constitute the bulk of sedimentary carbonates in the
geologic record and are widely used archives of Earth's chemical and climatic history. One …

We present a commercially-available, fully-automated, offline chromatography method
capable of simultaneously purifying both Ca and Sr for stable and radiogenic isotope …

The ability to rapidly detect changes in bone mineral balance (BMB) would be of great value
in the early diagnosis and evaluation of therapies for metabolic bone diseases such as …

Li, B, Mg and Ca isotopes became of increasing interest during the last decade due to their
potential for better constraining the carbon cycle and nutrient cycling. At the soil-water-plant …

As a component of many minerals and an essential trace element in most aerobic
organisms, the transition metal element Cu is important for studying reduction-oxidation …

High‐precision calcium isotopic compositions of a set of geological reference materials from
the IAG (OU‐6), ANRT (UB‐N), MPI‐DING, USGS and GSJ, relative to NIST SRM 915a, are …

This paper reports measurements of mass-independent and mass-dependent Ca isotope
variations using the prototype collision cell MC-ICPMS/MS, Proteus. Helium and hydrogen …

Shallow water carbonates from Florida Bay, the Florida Reef Tract, and a Mexican
Caribbean fringing reef at Punta Maroma were studied to determine the range of Ca-isotope …
