Lead (Pb) isotopic analyses proved to be a very efficient tool for tracing the sources of local
and global Pb pollution. This review presents an overview of literature published on the use …

Of the long-lived chronometric systems, only the dual decay of 238 U and 235 U to 206 Pb
and 207 Pb, respectively, have appropriate half-lives to resolve the ages of meteorites and …

Abstract Mixed 235 U–233 U–205 Pb (–202 Pb) tracers for U–Pb isotope-dilution isotope
ratio mass spectrometry have been prepared under the auspices of the EARTHTIME …

From measurements of Hf–Yb mixtures, we have found that the correction of isobaric
interferences involving accepted Yb isotope ratios and reasonable estimates of mass bias …

A Pb isotope analytical method using a 207Pb–204Pb double spike (DS) and a double-
focusing MC-ICP-MS routinely yields standard and sample data with an external …

New techniques of isotopic measurements by a new generation of mass spectrometers
equipped with an inductively-coupled-plasma source, a magnetic mass filter, and multiple …

Siletzia is a basaltic Paleocene and Eocene large igneous province in coastal Oregon,
Washington, and southern Vancouver Island that was accreted to North America in the early …

Chemical weathering consumes atmospheric carbon dioxide through the breakdown of
silicate minerals and is thought to stabilize Earth's long-term climate. However, the potential …

Pb isotope analyses using multicollector magnetic sector inductively coupled plasma mass
spectrometers (ICP-MS) may potentially be corrected for mass bias, a major source of …

Multiple-collector magnetic sector ICP-MS affords the possibility of applying instrumental
mass discrimination corrections using a reference isotope ratio of an element (dopant) other …
