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.

Serpentinite vs Migmatite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Serpentinite vs Migmatite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Serpentinite and Properties of Migmatite. Learn more about Serpentinite vs Migmatite in the next section. The interior uses of Serpentinite include Decorative aggregates and Interior decoration whereas the interior uses of Migmatite include Countertops, Flooring and Kitchens. Due to some exceptional properties of Serpentinite and Migmatite, they have various applications in construction industry. The uses of Serpentinite in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement and that of Migmatite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.
More about Serpentinite and Migmatite
Here you can know more about Serpentinite and Migmatite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Migmatite consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Migmatite includes Biotite, Chlorite, Feldspar, Garnet, Graphite, Hornblade, Micas, Muscovite or Illite, Quartz, Quartzite, Silica, Zircon. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Migmatite, the texture, color and appearance plays an important role in determining the type of rock. Serpentinite is available in black, brown, colourless, green, grey, white colors whereas, Migmatite is available in black, bluish - grey, brown, brown- black, dark greenish - grey, dark grey to black colors. Appearance of Serpentinite is Rough and Dull and that of Migmatite is Dull, Banded and Foilated. Properties of rock is another aspect for Serpentinite vs Migmatite. The hardness of Serpentinite is 3-5 and that of Migmatite is 5.5-6.5. The types of Serpentinite are Jadeitite whereas types of Migmatite are Diatexites and Metatexites. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Serpentinite and Migmatite is white, greenish white or grey. The specific heat capacity of Serpentinite is 0.95 kJ/Kg K and that of Migmatite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Serpentinite is heat resistant whereas Migmatite is heat resistant, pressure resistant.
