How do magmas evolve? - ️️crystal settling: earlier-formed minerals are denser than the liquid portion of the magma and sink to the base of the magma chamber magmatic differentiation: the formation of one or more secondary magmas from a single parent magma assimilation: as magma migrates through the crust, it may incorporate some of the surrounding rock magma mixing: during the ascent of 2 chemically different magma bodies, the more buoyant mass may overtake the slower-rising bo...
