3D Diffusion of Water in Melt Inclusion‐Bearing Olivine Phenocrysts

Geochemistry, Geophysics, Geosystems
Olivine‐hosted melt inclusions are an important archive of pre‐eruptive processes such as magma storage, mixing and subsequent ascent through the crust.

Simultaneous In Situ Determination of Pb Isotope Ratios and Trace Element Concentrations in Melt Inclusions by LASS‐ICP‐MS

Geochemistry, Geophysics, Geosystems, 2021
Melt inclusions provide unique insights into magmatic sources and processes. This study presents a method for simultaneously measuring Pb isotopes and trace elements in melt inclusions using a 193 nm excimer laser ablation system coupled to a multiple ...

Channelized melt flow in downwelling mantle: Implications for 226Ra-210Pb disequilibria in arc magmas [PDF]

, 2008
We present the results of an analytical model of porous flow of viscous melt into a steadily dilating ‘‘channel’’ (defined as a cluster of smaller veins) in downwelling subarc mantle.

Testing the Recycled Gabbro Hypothesis for the Origin of “Ghost Plagioclase” Melt Signatures Using 87Sr/86Sr of Individual Olivine‐Hosted Melt Inclusions From Hawai'i

Geochemistry, Geophysics, Geosystems, 2021
Melt inclusions with large, positive Sr anomalies have been described in multiple tectonic settings, and the origins of this unusual geochemical feature are debated.

Melt-melt immiscibility and implications for the origin of Madeira albite-rich granite, Pitinga mine, Amazonas, Brazil: A melt inclusion study

Brazilian Journal of Geology, 2022
Presented here are the results of the first studies of silicate melt inclusions hosted in quartz crystals from the two late granitic facies of the Paleoproterozoic Madeira pluton in the Pitinga mine, State of Amazonas, Brazil. The study of these magmatic

Aerospace Titanium Alloy Melt Process Quality Improvements [PDF]

MATEC Web of Conferences, 2020
This Jet Engine Titanium Quality Committee (JETQC) paper describes industry quality improvements since 1990. Quality refers to freedom from melt-related hard-alpha and high-density inclusions (HDI). JETQC, formed under the auspices of the U.S.

Melt Inclusion Evidence for Magma Evolution at Mutnovsky Volcano, Kamchatka [PDF]

, 2013
Mutnovsky Volcano, located in Kamchatka, Russia, is a young volcano that has formed a series of four overlapping stratocones over its approximately 80 ka history. Erupted products at Mutnovsky range in composition from basalts to dacites; basalts are the

The inclusion removal behavior during electron beam smelting of DD98M alloy

Journal of Materials Research and Technology, 2022
The DD98M alloy was prepared by electron beam smelting, and the effect of electron beam smelting parameters on the inclusion removal behavior was studied. The inclusion removal thermodynamics and kinetic mechanisms were analyzed.

Engulfment and Pushing of Cylindrical Liquid Nano-Inclusion by Advancing Crystal/Melt Interface: An Atomistic Simulation Study

Nanomaterials, 2023
We reported a molecular dynamics (MD) simulation study of an advancing pure Al(100)/melt interface that encounters a foreign immiscible liquid Pb cylindrical nano-inclusion. When the advancing interface approaches the inclusion, the interface may engulf,
