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

Geostandards 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.

Isotopic Data on Diet and Mobility from Pictish and Viking Age Orkney

Journal of Open Archaeology Data
Changes in diet and mobility isotopes from the Late Iron Age or Pre-Viking phase (PVP, AD 550–790) through the Viking Age (VA, AD 790–1050) and Late Norse phase (LNP, AD 1050–1300) can be used to suggest nuanced socioeconomic and political change ...

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

Geostandards 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.

Virocell Necromass Provides Limited Plant Nitrogen and Elicits Rhizosphere Metabolites That Affect Phage Dynamics

Plant, Cell &Environment, EarlyView.
ABSTRACT Bacteriophages impact soil bacteria through lysis, altering the availability of organic carbon and plant nutrients. However, the magnitude of nutrient uptake by plants from lysed bacteria remains unknown, partly because this process is challenging to investigate in the field.

Multi‐Elemental Analysis for Geographical Tracing of Chickpeas Produced in Nearby Locations Around a Protected Geographical Indication

Plant, Cell &Environment, EarlyView.
ABSTRACT The multi‐elemental profile has repeatedly been proposed as a reliable indicator of the geographical origin of plant‐derived foods, as mineral composition accurately reflects the local soil geochemistry and environmental factors. However, this approach may fail in distinguishing specimens from nearby locations, which are expected to be exposed
