Definition of migmatite in English English dictionary

any rock of mixed appearance, being an intimate mixture of granite and older rock, specifically from intense metamorphism which partially melts the rock, causing it to recrystallize in a state intermediate between igneous and metamorphic

Rock composed of a metamorphic host material that is streaked or veined with granite; the name means "mixed rock. " Many migmatites probably represent partial fusion of the metamorphic host; some components of the rock are fused and gather to produce the streaks of granite. Migmatite also can form near large intrusions of granite when some of the magma is injected into neighbouring metamorphic rocks
