The development of multi-collector inductively coupled plasma mass spectrometry (MC-ICP-
MS) in 1992 opened up new opportunities for geochemical, mineral exploration, and …

Highlights in the field of air analysis included: a new focus on measuring tyre-wear particle
emissions; an interest in using unmanned aerial vehicles for sampling purposes and an …

Age determination of minerals using the U–Pb technique is widely used to quantify time in
Earth's history. A number of geochronology laboratories produce the highest precision U–Pb …

Zirconium is a commonly used elemental tracer of silicate differentiation, yet its stable
isotope systematics remain poorly known. Accessory phases rich in Zr4+ such as zircon and …

Uranium isotope ratios are widely utilized in paleoceanography. The 238 U/235 U ratio
(expressed as δ 238 U) is leveraged as a proxy for the areal extent of anoxic seafloor, and …

Conflicting results exist regarding the mechanisms, direction, and magnitude of Zr isotope
fractionation in igneous systems. To better understand the origin of the fractionations …

As the parent element in the U-Pb and Pb-Pb radiochronometers, uranium (U) was one of
the first heavy elements whose isotopic composition was carefully determined. Thought to …

We use rapidly cooled achondrites to test the assumption of 26 Al homogeneity in the solar
nebula, by checking if there is a single value of t SS, the absolute “Pb-Pb” age of the Solar …

The uranium isotope composition (δ 238 U) of seawater is a powerful proxy for the extent of
marine anoxia. For paleoredox reconstructions, carbonates are the most popular U isotope …

Stable isotopes provide deep insights into processes across a wide range of scales, from
micron-to cosmic-size systems. Here, we review how continued advances in mass …
