Melt extraction and accumulation from partially molten rocks
Lithos, 2004Current models for melt segregation and ascent are not adequate to accurately describe transport and accumulation in combination. We propose that transport is discontinuous and in batches, and that accumulation occurs by stepwise merging of batches. A simple numerical model of jostling spheres that merge when they touch was used to represent stepwise ...

Permeability of asthenospheric mantle and melt extraction rates at mid-ocean ridges
Nature, 2009Magmatic production on Earth is dominated by asthenospheric melts of basaltic composition that have mostly erupted at mid-ocean ridges. The timescale for segregation and transport of these melts, which are ultimately responsible for formation of the Earth's crust, is critically dependent on the permeability of the partly molten asthenospheric mantle ...

Melt extraction of short metallic filaments: Fibre formation process revisited
Journal of Materials Processing Technology, 2008This article presents experimental results of the extraction of metallic fibres from the surface of a melt pool. A low-melting alloy was used in a model facility to produce filaments of equal length. Operational parameters such as wheel speed and feed rate were varied to yield thin fibres.

Microstructure studies of melt-extracted Nd-Fe-B fibers
Journal of Magnetism and Magnetic Materials, 1992Abstract The correlation between quenching conditions and microstructure of Nd-Fe-B fibers obtained by melt-extraction method has been studied. The structure of as-quenched fibers was observed by Scanning Electron Microscopy (SEM) on fracture cross section and by Transmission Electron Microscopy (TEM).

Volumetrically significant melt production requires crustal temperatures above approximately 800 ° C. At the grain scale, the former presence of melt may be inferred based on various microstructures, particularly pseudomorphs of melt pores and grain-boundary melt films. In residual migmatites
