RioM‐1: A New Calcite Reference Material for U‐Pb LA‐ICP‐MS Geochronology

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points RioM‐1 calcite was characterised for trace elements, U‐Pb geochronology, Sr and O isotopes using ID‐TIMS, LA‐ICP‐MS and SIMS. U‐Pb dates from ID‐TIMS and LA‐ICP‐MS across several independent laboratories returned identical results within uncertainty.

Six Ca‐Mg‐Fe Carbonate Reference Materials for In Situ Measurement of Oxygen and Carbon Isotope Ratios

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points Six new Ca‐Mg‐Fe carbonate reference materials are available to the global geochemical community for calibrating oxygen and carbon isotope ratios by SIMS. Significant compositional matrix effects were observed in the dolomite‐ankerite and magnesite‐siderite series during SIMS analysis. Compositional matrix effects correlate with Fe variation.

Facilitated Transport of Organic Contaminants in a High Concentration, Multicomponent Plume

open access: yesGroundwater Monitoring &Remediation, EarlyView.
Abstract A field experiment evaluated the transport of organic contaminants in a plume from hazardous waste disposal areas at the Rocky Mountain Arsenal. The plume contained many xenobiotic contaminants, with widely varying expected mobilities.
