Partial melting is the transformation of some fraction of the mass of a solid rock into a liquid as a result of decompression, heat input, or addition of a flux. The resulting liquid is called magma and becomes lava if it erupts from a volcano. The understanding that partial, rather than complete, melting is the norm in natural systems is essential to ...

Attenuation in partially melted material
Journal of Geophysical Research, 1968Expressions for the complex moduli are derived for two models that simulate the structure of partially melted material. In one model, isolated lens-shaped inclusions of melt form the liquid phase, whereas in the other model the liquid phase is a continuous film of melt surrounding approximately spherical solid grains.

Water and partial melting of Earth’s mantle
Science China Earth Sciences, 2016Abstract Water plays a crucial role in the melting of Earth’s mantle. Mantle magmatisms mostly occur at plate boundaries (including subduction zones and mid-ocean ridges) and in some intraplate regions with thermal anomaly. At oceanic subduction zones, water released by the subducted slab may induce melting of the overlying mantle wedge or even the ...

The role of subgrain boundaries in partial melting
Journal of Structural Geology, 2016Abstract Evidence for partial melting along subgrain boundaries in quartz and plagioclase is documented for rocks from the Lost Creek Gneiss of the Llano Uplift, central Texas, the Wet Mountains of central Colorado, and the Albany-Fraser Orogen, southwestern Australia.

Partial melting of filamentary Ho1Ba2Cu3Ox superconductors
Physica C: Superconductivity, 2004Abstract We prepared precursor filamentary Ho 1 Ba 2 Cu 3 O x superconductors by a solution spinning. The filamentary precursor was partially melted in flowing O 2 under various heating conditions. The J c value of the sample was strongly dependent on the flowing O 2 rate.

Partial Melting and Melt Segregation in a Convecting Mantle
2000Various causes for mantle melting (decompression, heating or release of water) combined with current estimates of upper mantle temperatures and the state of stress in the lithosphere suggest that in many regions the asthenosphere might be partially molten, but melts may not always be able to rise to the surface.

Partial melting of subducting oceanic crust
Earth and Planetary Science Letters, 1994The conditions under which partial melting of subducting oceanic crust occurs can be determined by combining a partial melting model for basaltic compositions with two-dimensional thermal models of subduction zones. For porosities of ~ 1% containing H20 the amount of partial melt generated at the wet basaltic solidus is limited to ~ 100 MPa) can be ...

Partial melting and recrystallization of isotactic polypropylene
Chinese Journal of Polymer Science, 2009A relatively high predetermined crystallization temperature (135°C) was chosen to grow well developed iPP spherulites, then the partial melting was carried out at a temperature of 165°C, where the preformed spherulites were seen to only decrease their size but not completely melted.

Residual peridotites and the mechanisms of partial melting
Earth and Planetary Science Letters, 1985Using the isotope dilution technique, we have determined rare earth element abundances in the New Caledonian ophiolitic melting residues. The main problem dealt with is the mechanism of partial melting as constrained by the partitioning of incompatible elements during melting (i.e. batch, fractional or disequilibrium melting).
