| Abstract |
The goal of this experimental study is to understand the relation
between deformation and melt migration in partially molten rocks
and to find out how melt actually moves as a function of varying
temperature, stress, lithostatic pressure, magma pressure, strain
rate, and time. Partly molten rocks will be tested in hydrostatic
melt extraction experiments under conditions of varying pressure,
with one or two solid phases, and with melt of variable amount and
viscosity, which will result in significant differences in permeability
in different experiments. Triaxial deformation experiments will
also be carried out at variable temperatures, melt percents, and
strain rates. Samples will be carefully examined before and after
the experiments to evaluate physical properties. Permeabilities
will be measured directly in some of the experiments. Results will
be evaluated in light of previous experiments and theoretical considerations.
