Electrical Conductivity of Hydrous Ultramafic Melts With Implications for Origin of Low Velocity Layer Atop of the 410 km Seismic Discontinuity

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Low‐velocity layers (LVLs) above the 410‐km discontinuity are commonly attributed to partial melt generated by dehydration melting when hydrous mantle transition‐zone material rises into the upper mantle, where water solubility in nominally anhydrous minerals decreases.

THERMOBAROMETRY OF DEPLETED PERIDOTITES

Geodynamics & Tectonophysics
An assessment was made of the possibility of using olivine thermobarometry for xenoliths of depleted peridotites from the Udachnaya pipe (Yakutia), represented by 76 megacrystalline dunites and 5 megacrystalline harzburgites. Specially developed and tested method of microprobe analysis was used to determine Al and Ca microimpurities in the olivine ...

Variations in Hawaiian Plume Flux Controlled by Ancient Mantle Depletion

AGU Advances
Mantle plumes—upwellings of buoyant rock in Earth's mantle—feed hotspot volcanoes such as Hawai‘i. The size of volcanoes along the Hawai‘i–Emperor chain, and thus the magma flux of the Hawaiian plume, has varied over the past 85 million years.

Assessing the environmental impact of Kolaka peridotites from nickel mining waste for geological carbon storage: Mineralogy, carbonation potential, and rock property changes

Journal of Degraded and Mining Lands Management
This study investigated the carbonation potential of peridotite from the Kolaka Ultramafic Complex in Sulawesi, Indonesia, for carbon capture and storage (CCS) applications.

Estimasi Ukuran Bulir Mineral Magnetik pada Batuan Peridotit Berdasarkan Peluruhan Anhysteretic Remanent Magnetization (ARM)

Jurnal Fisika Flux, 2017
A decaying measurement of Anhysteretic Remanent Magnetization (ARM) has been undertaken to estimation the grain size of magnetic mineral which carries remanent on peridotite igneous rocks.

Biobased biodegradable chelating agents enhance coupled ex situ and in situ carbon dioxide mineralization via peridotite dissolution and wormholing

Communications Earth & Environment
Mantle peridotite, which is also present in near-surface environments, reacts readily with CO2, and is expected to be suitable for CO2 mineralization.
