Migmatite and Suevite
Definition
Definition
Migmatite is typically a granitic rock within a metamorphic host rock which is composed of two intermingled but distinguishable components
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Formation
Formation
Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

All about Migmatite and Suevite Properties
Know all about Migmatite and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Migmatite and Suevite belong to Metamorphic Rocks.Texture of Migmatite is Foliated whereas that of Suevite is Earthy. Migmatite appears Dull, Banded and Foilated and Suevite appears Banded. The luster of Migmatite is dull to pearly to subvitreous while that of Suevite is earthy. Migmatite is available in black, bluish - grey, brown, brown- black, dark greenish - grey, dark grey to black colors whereas Suevite is available in black, brown, colourless, green, grey, pink colors. The commercial uses of Migmatite are cemetery markers, jewelry, tombstones, used to manufracture paperweights and bookends and that of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
