The reaction mechanism of fluid-induced partial melting of gabbro in the oceanic crust
, 2013Hydrous partial melting of oceanic gabbro as a consequence of fluid/rock interaction at very high temperatures is regarded as an important process for the formation of felsic lithologies within the oceanic crust.

Partial melting of bulk NdBa2Cu3O7−δ
Il Nuovo Cimento D, 1994Two procedures of partial melting of bulk NdBa2Cu3O7−δ, in air and in reduced oxygen pressure, were developed. When the treatment was carried out in air, poor superconducting properties were observed. On the contrary, when the treatment was carried in PO2=1.3 mbar, good properties were obtained, with Tconset=93 K and 100% shielding at lower ...

Melting and dissolution kinetics: Application to partial melting and dissolution of xenoliths
Journal of Geophysical Research: Solid Earth, 1986Kinetics of melting and dissolution (rates and textures) in magmatic systems is reviewed and applied to partial melting and dissolution of xenoliths. Special attention is paid to melting/dissolution of solid solution crystals, in which characteristic cloudy textures are formed, and diffusion of elements in the crystals plays an important role due to ...

Partial melting and the low-velocity zone
Physics of the Earth and Planetary Interiors, 1970The effect of partial melting on the elastic properties of polycrystalline material is a strong function of the shape of the melt zones. If the lowest melting constituents are concentrated in narrow zones, such as grain boundaries, a small amount of melt, ≈ 1%, can easily explain the upper mantle low-velocity zone, for both shear waves and ...

The crystallization of polyethylene after partial melting
Polymer, 1963Abstract The crystallization of polyethylene has been shown to be independent of the previous temperature of melting, even when the melting point is exceeded by as little as 0·3°C. The persistence of nuclei which are progressively removed as the temperature is raised above the melting point is thus excluded.

Partial melting mechanisms of embedded nanocrystals
Physical Review B, 2009Understanding the melting mechanisms of nanocrystals embedded in solids is of great current interest since both the synthesis and modification of such systems frequently involve the use of high temperatures. Using molecular-dynamics computer simulations we study the melting mechanisms of Cu, Ag, and Au nanoclusters embedded in metal matrices and Si ...

Partial melting under spreading ridges
Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1978Factors of importance in partial melting calculations are discussed. The thermal evolution of a geochemical and petrological model of the upwelling asthenosphere beneath a ridge crest is studied numerically. Partial melting, basalt eruption and differentiation of the upwelling asthenosphere is modelled. Melt distribution and density distribution in the

Pn velocity and partial melting—discussion
Tectonophysics, 1977Abstract The seismologically observed Pn velocity anomalies in the conterminous United States are restricted to the lithosphere, but the observed teleseismic delay-time variations are due principally to the regional variations in the physical state (i.e., thickness of lowvelocity zone and/or percent melt, etc.) of the asthenosphere.
