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

Magmatic differentiation mechanisms of the continental crust : the permian magmatic systems of Western Europe

L’objectif de cette thèse vise à contraindre le rôle du magmatisme sur la diversité en composition et sur la modification de l’architecture de la croûte continentale. Cette étude se focalise sur l’intrusion du complexe gabbroïque de Sondalo (Italie du Nord), mis en place en croûte moyenne dans un contexte post-orogénique.

Estimating Sub‐Pixel Temperatures During Volcanic Eruptions Using Dual‐Band Thermal Imaging Technique: Case Studies From Whakaari/White Island (New Zealand) and Tofua (Tonga)

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.
This study presents the first application of a dual‐band satellite thermal monitoring technique in New Zealand and Tonga, using the 2019 eruption of Whakaari/White Island and the persistently active Lofia crater on Tofua volcano as case studies. At Whakaari/White Island, near‐synchronous Landsat‐8 and Sentinel‐2A data (16 min interval) were analysed ...

Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...
