Hydrated Peridotite–Basaltic Melt Interaction Part II: Fast Assimilation of Serpentinized Mantle by Basaltic Magma

Frontiers in Earth Science, 2020
The most abundant terrestrial lavas, mid-ocean ridge basalt (MORB) and ocean island basalt (OIB), are commonly considered to be derived from a depleted MORB-mantle component (DMM) and more specific, variably enriched mantle plume sources.

Combustion and Pyrolysis EA‐IRMS Techniques to Determine the δ2H of Diamonds

Rapid Communications in Mass Spectrometry, Volume 40, Issue 10, 30 May 2026.
ABSTRACT Rationale Diamonds are generally considered to be metasomatic minerals originating from the Earth's mantle. They formed through the interaction of carbon‐bearing fluids or melts with the surrounding deep lithology. Most knowledge about the formation of diamonds comes from studying their mineral inclusions or stable isotopes.

Assessing the Impacts of Recent Crop Expansion on Water Quality in the Missouri River Basin Using the Soil and Water Assessment Tool

Journal of Advances in Modeling Earth Systems, 2021
The Missouri River Basin (MORB) has experienced a resurgence of grassland conversion to crop production, which raised concerns on water quality. We applied the Soil and Water Assessment Tool (SWAT) to address how this conversion would impact water ...

Phase Relations and Melting of SiO2 Under Mantle Conditions Determined From Machine Learning Potentials

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract SiO2 is a fundamental component of planetary interiors, yet its high‐pressure melting and phase relations remain uncertain. We develop a machine learning potential with first‐principles accuracy and perform large‐scale two‐phase coexistence simulations to determine the melting curves of stishovite, post‐stishovite, and seifertite up to 160 GPa

Origins of the Pangkaimen Au Deposit in the Northern Great Xing'an Range, China: Evidence From Geochronological, Geochemical, Fluid Inclusion, and H–O–S–Pb Isotope Data

Geological Journal, Volume 61, Issue 5, Page 1291-1309, May 2026.
The Pangkaimen Au–Ag deposits belong to the epithermal Au deposits, which are of great significance for guiding the research and development of this type of gold deposit. Metallogenic model diagram of Pangkaimen Au–Ag deposit. ABSTRACT The gold (Au) metallogenic belt in the northern Great Xing'an Range is characterised by the wide occurrence of the ...

The Missing Magmas of MOR: Insights From Phase Equilibrium Experiments on Plagioclase Ultraphyric Basalts

Geochemistry, Geophysics, Geosystems, 2022
Plagioclase ultraphyric basalts (PUBs) are a class of mid‐ocean ridge (MOR) lavas found in a variety of ocean floor environments, are characterized by abundant (15–40 volume %) plagioclase megacrysts and a diverse trace element and isotopic signature ...

Interior Rifting Coupled With Peripheral Subduction in the Rodinia Supercontinent: New Insights From the Tarim Craton

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract After assembly, supercontinents are shaped by internal rifting and peripheral subduction. However, the geodynamic relationship between these two processes and their respective contributions to supercontinent breakup remain poorly understood.

Petrological variability of recent magmatism at Axial Seamount summit, Juan de Fuca Ridge

Geochemistry, Geophysics, Geosystems, 2013
A combined study of mapping, observational, age constraint, and geochemical data at the summit of Axial Seamount, Juan de Fuca Ridge, has revealed its recent petrological history. Multiple basalt types erupted at the summit in a time sequence.

Multipole decomposition of LDA+$U$ energy and its application to actinides compounds

, 2009
A general reformulation of the exchange energy of $5f$-shell is applied in the analysis of the magnetic structure of various actinides compounds in the framework of LDA+U method. The calculations are performed in an efficient scheme with essentially only
