Definition

A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.

Migmatite is typically a granitic rock within a metamorphic host rock which is composed of two intermingled but distinguishable components

Formation

Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.

All about Serpentinite and Migmatite Properties

Know all about Serpentinite and Migmatite properties here. All properties of rocks are important as they define the type of rock and its application. Serpentinite and Migmatite belong to Metamorphic Rocks.Texture of Serpentinite is Earthy whereas that of Migmatite is Foliated. Serpentinite appears Rough and Dull and Migmatite appears Dull, Banded and Foilated. The luster of Serpentinite is waxy and dull while that of Migmatite is dull to pearly to subvitreous. Serpentinite is available in black, brown, green, grey, white colors whereas Migmatite is available in black, bluish - grey, brown, brown- black, dark greenish - grey, dark grey to black colors. The commercial uses of Serpentinite are commemorative tablets, creating artwork and that of Migmatite are cemetery markers, jewelry, tombstones, used to manufracture paperweights and bookends.
