Eutectic Melting First melt always = eutectic composition Major element composition of eutectic melt is constant until one of the source mineral phases is consumed Once a phase is consumed, the next increment of melt will be different composition (X) and T
Critical Melt Fraction Separation of a partially melted liquid from the solid residue requires a critical melt % Sufficient melt must be produced to 1. Form a continuous, interconnected film 2. Have enough volume so not all of it is adsorbed to the crystal surfaces
