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

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,

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.

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.

The global melt inclusion C/Ba array: Mantle variability, melting process, or degassing? [PDF]

, 2020
The Earth’s mantle holds more carbon than its oceans, atmosphere and continents combined, yet the distribution of carbon within the mantle remains uncertain.

Evaluation of Error Propagation in Lead Isotope Analysis of Ancient Melt Inclusions by LA-MC-ICP-MS

Yankuang ceshi, 2015
Determination of Pb isotopes in melt inclusions by Laser Ablation -Multiple Collector-Inductively Coupled Plasma-Mass Spectrometry (LA-MC-ICP-MS) is limited to samples formed later than Mesozoic because U and Th signals are not monitored.

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.

Petrogenetic history and melt inclusion characteristics of mantle plume-derived ijolites from NE India: implications for multistage crystallization and occurrence of “nano-calciocarbonatites”

Progress in Earth and Planetary Science, 2022
The Sung Valley ultramafic–alkaline–carbonatite complex (UACC) of Meghalaya, NE, India, is a result of magmatic activity related to the Kerguelen mantle plume spanning from 101 to 115 Ma. In the present study, an integrated crystal size distribution (CSD)

Optimization of flow control devices in a ten-strand billet caster tundish [PDF]

China Foundry, 2016
The physical model of a ten-strand billet caster tundish was established to study the effects of various flow control devices on the melt flow. Before and after the optimization of the melt flow, the inclusion removal in the tundish was evaluated by ...
