Polybaric Near-Fractional Melting - John Seach During magma ascent through the earth's
mantle the melt may separate from the mantle causing a change in the composition
of the system. As long as equilibrium does not occur the fractions will
still maintain the pressure signal of the original conditions. This is
called polybaric near-fractional melting.
