Geochemistry of Ocean Floor and Fore-arc Serpentinites: Constraints on the Ultramafic Input to Subduction Zones [PDF]
, 2017 We provide new insights into the geochemistry of serpentinites from mid-ocean ridges (Mid-Atlantic Ridge and Hess Deep), passive margins (Iberia Abyssal Plain and Newfoundland) and fore-arcs (Mariana and Guatemala) based on bulk-rock and in situ mineral ...

Laser Ablation Sampling With Low‐Power Plasma: A LA‐MIP‐MS Instrument for Spaceflight
Rapid Communications in Mass Spectrometry, Volume 40, Issue 3, 15 February 2026.ABSTRACT Rationale Inductively coupled plasma (ICP) is a commonly used ion source for mass spectrometry‐based chemical analysis of a wide range of materials. Traditional ICP ion sources use high power (> 1000 W) and significant gas flow (> 10 L/min), rendering them unsuitable for spaceflight, as they are too resource‐intensive for planetary spacecraft.

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.Abstract The eastern margin of the Sea of Japan is a zone of great seismic and tsunami hazard due to multiple offshore and nearshore reverse faults as shown by the 2024 Mw ${M}_{\mathrm{w}}$ 7.5 Noto Peninsula Earthquake. Here we compare coseismic deformation of the 2024 Noto Peninsula Earthquake with 4,767 individual marine terraces attributed to 16 ...

Beyond Oxygen Fugacity: A Compositional Metric to Probe Earth's Redox Structure
Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.Abstract We quantify the redox capacity (dO2) by redox titration—defined as the quantity of oxygen required to fully oxidize a sample—for rocks spanning Earth's upper mantle to surface sediments. The values span three orders of magnitude, with the greatest variability in metamorphic and surface rocks that host both highly reduced (rich in carbon and ...

The Buoyancy of Cratonic Lithospheric Mantle
Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.Abstract Cratons are generally thought to be characterized by stable, long‐lived mantle roots. However, recent studies have suggested that the lithospheric mantle may be prone to removal, implying that it may be denser than the asthenosphere. To address these suggestions, we use a global data set of mantle xenoliths to estimate the density structure of

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.Abstract Geothermal reservoirs commonly record seismic and creep events, constituting earthquake hazards in enhanced geothermal systems. To understand the geological controls on mixed‐mode frictional behaviors in these settings, we performed friction experiments on fault gouges from the polyphase‐altered carbonate Massenkalk Formation in Germany, a ...

Elevated temperature effects on swelling pressure of compacted bentonite
Deep Underground Science and Engineering, Volume 4, Issue 4, Page 699-708, December 2025.We present a set of new experimental investigations on the effects of elevated temperature on the swelling pressure development of compacted bentonite. This research was motivated by an emerging interest in using bentonite as a plug material in oil and gas well abandonment.
