Mineral deposit - Immiscible melts | Britannica

Mineral deposit - Mineral deposit - Immiscible 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). The chemical principle governing precipitation of an immiscible liquid is the ...
