Magma Ascent by Porous Flow

  title={Magma Ascent by Porous Flow},
  author={David R Scott and D. J. Stevenson},
Porous flow of buoyant liquid through partially molten rock is regarded as the initial transport process leading to magma segregation in the mantle. Recent work has identified the importance of matrix deformation and compaction in this process. We present finite-difference calculations based on a generalized form of Darcy's law that includes matrix deformation, in two-dimensional Cartesian and cylindrical coordinates. We emphasize the existence of solitary wave solutions, called magmons. These… CONTINUE READING
