Magmatic to solid-state evolution of a shallow emplaced agpaitic tinguaite (the Suc de Sara dyke, Velay volcanic province, France): implications for peralkaline melt segregation and extraction in ascending magmas [PDF]
European Journal of MineralogyIn the last decades the mush model has been generalized to the complete trans-crustal magmatic system in which differentiation would be driven by segregation and extraction of trapped melts from crystal-rich mushes. Melt extraction processes involved are

Enhanced magnetocaloric performance in nanocrystalline/amorphous Gd3Ni/Gd65Ni35 composite microwires
Journal of Science: Advanced Materials and Devices, 2021 A novel class of nanocrystalline/amorphous Gd3Ni/Gd65Ni35 composite microwires were created directly from melt-extraction through controlled solidification.

Molecules, 2023 Polyhydroxyalkanoates (PHAs) are natural polyesters which biodegrade in soils and oceans but have more than double the cost of comparable oil-based polymers. PHA downstreaming from its biomass represents 50% of its overall cost.

Chemical diffusion of fluorine in jadeite melt at high pressure [PDF]
, 1984 The chemical diffusion of fluorine in jadeite melt has been investigated from 10 to 15 kbars and 1200 to 1400°C using diffusion couples of Jadeite melt and fluorine-bearing jadeite melt (6.3 wt.% F). The diffusion profile data indicate that the diffusion

Tracking Crystal‐Melt Segregation and Accumulation in the Intermediate Magma Reservoir
Geophysical Research Letters, 2023 The genesis of intermediate intrusions is highly controversial, and one of the hot topics is whether they represent frozen melts or cumulates in the evolution of magmatic systems. Distinguishing accumulation from crystallization melt differentiated along

Effects of water and fluorine on the viscosity of albite melt at high pressure: a preliminary investigation [PDF]
, 1985 The viscosities of fluorine- and water-bearing melts based on albite composition have been determined at 7.5, 15 and 22.5 kbar by the falling-sphere method. All melt viscosities decrease isothermally with increasing pressure.

Influence of Lithology on Reactive Melt Flow Channelization
Geochemistry, Geophysics, Geosystems, 2020 To investigate channelization during migration of a reactive melt, we performed a series of Darcy‐type experiments in which an alkali basalt infiltrated partially molten harzburgites and lherzolites at a confining pressure of 300 MPa, temperatures of ...

Accessory Mineral Eu Anomalies in Suprasolidus Rocks: Beyond Feldspar
Geochemistry, Geophysics, Geosystems, 2020 Accessory mineral Eu anomalies (Eu/Eu*) are routinely measured to infer changes in the amount of feldspar over time, allowing accessory mineral U‐Pb dates to be linked to the progressive crystallization of igneous and metamorphic rocks and, by extension,
