    The magmatic segregation and formation of pegmatites leaves the residual magma very fluid and it contains gases of great chemical activity. These gases penetrate the adjacent country rock and by their reaction with the latter form mineral deposits Such deposits are known as pneumatolydc ore deposits. Examples are cassiterite deposits.

    Mineral deposit - Mineral depositImmiscible melts A different kind of magmatic segregation involves liquid immiscibility. A cooling magma will sometimes precipitate droplets of a second magma that has an entirely different composition. Like oil and water the two magmas will not mix (i.e. they are immiscible).
