Migmatite is typically a granitic rock within a metamorphic host rock which is composed of two intermingled but distinguishable components
From the Greek word migma which means a mixture
Durable Rock, Medium Hardness Rock
Coarse Grained Rock, Fine Grained Rock, Medium Grained Rock, Opaque Rock
Black, Bluish - Grey, Brown, Brown- Black, Dark Greenish - Grey, Dark Grey to Black
Dull, Banded and Foilated
Countertops, Flooring, Kitchens
As Building Stone, As Facing Stone
As Dimension Stone, Cement Manufacture, for Road Aggregate, Making natural cement
Cemetery Markers, Jewelry, Tombstones, Used to manufracture paperweights and bookends
Diatexites and Metatexites
Generally rough to touch, Is one of the oldest rock
Archaeological Significance
Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.
