Kamron, Take a physical chemistry course. Then look at phase rules in the face of pressures of kilobars. You will find that the Gibbs energies are quite high enough to favor segregation of minerals into separate aggregates. Oh, another thing. A lot of underground minerology is in solution, with the respective fluids being CO2 and H2O – which are -NOT- miscible at high pressures. Quartz in particular is very often deposited from such superfluid vapors. — Norm
