Partial melting, partial melt extraction and partial back reaction in anatectic migmatites
Lithos, 2001Abstract Anatectic migmatites commonly show both prograde (entropy producing) and retrograde reactions between minerals and melt. The final textures, mineral modes and mineral chemistries are affected by four successive processes: (i) prograde partial melting and small-scale segregation into melt-rich domains and restitic domains; (ii) partial melt ...

Melt Generation and Extraction in Mantle Diapirs
1989The oceanic lithosphere, its physical, penological and geochemical nature, are largely a function of the magmatic processes which take place at oceanic spreading centers. An understanding of the processes of mantle melting and melt extraction is therefore central to models for the development of oceanic lithosphere.

Melt extraction of oxide ceramic fibers
1995Ceramic fibers are one of the most important categories of reinforcements for composite materials. This study deals with a novel melt extraction system which has been developed to produce fine oxide ceramic fibers. Four oxide compounds were selected for the production of fibers and characterization of the extraction system.

Trace Element Geochemical Effects of Integrated Melt Extraction and ‘Shaped’ Melting Regimes
Journal of Petrology, 1995Abstract The mixing (integration) of liquids obtained as different mass fractions of partial melting from source material of the same bulk composition, travelling along different mantle flow-lines through a melting regime, can result in deficiencies in the relative concentrations of those incompatible elements whose bulk distribution ...

Fabrication and Characterization of Slag Fiber by Melt Extraction
Materials Science Forum, 2007The influence of wheel speed and melt temperature on the surface characteristics of slag fibers were examined in mineral fibers synthesized from the steel-making slag, using a modified melt extraction method, i.e. melt spinning. The synthesized fibers were characterized by optical microscope and scanning electron microscopy. It was found that the wheel

Melt Extract Fibre Reinforced Sprayed Concrete
1985The performance of melt extract and wire fibre reinforced sprayed concretes produced at three field trials in the UK is reported. An emphasis was placed on measuring properties relevant to the applications of the material and in particular the effects of in situ fibre content and fibre type.

Physics of melt extraction: theory, implications and applications
Philosophical Transactions of the Royal Society of London. Series A: Physical and Engineering Sciences, 1993Abstract This paper presents a general overview of flow in deformable porous media with emphasis on melt extraction processes beneath mid-ocean ridges. Using a series of simple model problems, we show that the equations governing magma migration have two fundamentally different modes of behaviour.

Journal of Applied Physics, 1979
The wavelengths and directions of dimensional variations in metal ribbons quenched by Newtonian cooling from the melt are estimated for the melt-spinning and the melt-extraction processes. The main sources of dimensional variation are the vibration and distortion of the melt puddle from which the ribbon is solidified and the variation of the Newtonian ...
