After ca. 10 days, virtually all core material is partially molten, and vesiculation is pervasive.
In granitization, sediments are transformed in their solid state or in a partially molten state.
Jin, Z. M., Green, H. W. & Zhou, Y. Melt topology in partially molten mantle peridotite during ductile deformation.
"Essentially, the islands may be the tip of what was brought down and warmed up and became partially molten.
The surface topographies of the splats exhibited unmolten, partially molten, and completely molten splats.
We modelled a two-phase compositional system including a temperature-triggered phase transition from solid xenolith material to partially molten, low-density, vesiculated xenolith (vesicle-melt suspension), including the latent heat of fusion.
The pressure difference could be caused by hot, partially molten rock piled up beneath mid-ocean ridges or beneath the cooling plates diving into the earth at subduction zones, the authors write.
We present rheological data on samples of partially molten mantle rocks deformed in torsion at 1200 °C and 300 MPa in a gas-medium deformation apparatus.
However, the interface can affect the melt flow in deformed samples because the grain boundary melt film of several nanometer thickness exists stably in deformed partially molten rocks.
However, a melt film of 0.6- to 3.0-nm thickness was found in deformed partially molten olivine-orthopyroxene rocks (de Kloe et al. 2000).
Melt segregation is controlled by the permeability of the partially molten asthenosphere.
