When two immiscible (non-solid-solution-forming) minerals are mixed, the mixture exhibits eutectic behavior: the melting temperature of the mixture is depressed BELOW the melting point of either pure end-member, reaching a minimum (the eutectic temperature) at a specific mixture composition.
Because minerals A and B do not form a solid solution (no mutual solubility at the atomic scale), physically mixing them produces a system that...
