Experimental Evaluation and Optimisation of Sealed‐Tube Combustion Methods for Silicate Nitrogen Extraction

Rapid Communications in Mass Spectrometry, Volume 41, Issue 1, 15 January 2027.
ABSTRACT Rationale Nitrogen (N) abundance and isotopic compositions in silicate rocks are commonly measured by sealed‐tube continuous‐flow isotope ratio mass spectrometry (CF‐IRMS), but combustion protocols vary widely. It remains uncertain how the quality of data obtained from different published methods compares for differing sample types. Methods To

TIMS Techniques for Measuring Strontium Isotope Ratios in Apatite Grains and Application to Igneous Rock Petrology

Rapid Communications in Mass Spectrometry, Volume 41, Issue 1, 15 January 2027.
ABSTRACT Rationale This study evaluates the potential of Sr isotopic compositions in apatite grains from magmatic rocks as a proxy for initial 87Sr/86Sr ratios, addressing the need for alternative approaches to conventional whole‐rock analyses in isotopic studies of granitoid systems.

Low‐Temperature Experimental Characterization of Magnetite‐Based Rock‐Bed Thermal Battery

Energy Storage, Volume 8, Issue 8, December 2026.
The graphical abstract illustrates the proposed low‐temperature magnetite‐based rock‐bed thermal energy storage (RTES) concept for greenhouse applications and the corresponding experimental configuration. During charging, thermal energy is transferred from solar collectors to the RTES and is stored as sensible heat. During discharge, the stored heat is

Late Cenozoic Sediment Provenance in the Northern Canterbury Basin, Aotearoa New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.
Late Cenozoic strata of the northern Canterbury Basin record uplift and erosion of mountain ranges adjacent to the transition from oblique subduction to strike‐slip on the Australian–Pacific plate boundary. Using the provenance of conglomerate clasts and sandstone samples, we reconstruct sediment transport pathways and, by inference, exhumation and ...
