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'.
Minette is a variety of Lamprophyre and is porphyritic alkaline igneous rock which is mainly dominated by biotite and potassic feldspar

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.
Minette formation takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.

Serpentinite vs Minette 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 Minette characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Serpentinite and Properties of Minette. Learn more about Serpentinite vs Minette in the next section. The interior uses of Serpentinite include Decorative aggregates and Interior decoration whereas the interior uses of Minette include Countertops, Decorative aggregates and Interior decoration. Due to some exceptional properties of Serpentinite and Minette, 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 Minette include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Serpentinite and Minette
Here you can know more about Serpentinite and Minette. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Minette consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Minette includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Minette, 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, Minette is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Serpentinite is Rough and Dull and that of Minette is Dull, Banded and Foilated. Properties of rock is another aspect for Serpentinite vs Minette. The hardness of Serpentinite is 3-5 and that of Minette is 5-6. The types of Serpentinite are Jadeitite whereas types of Minette are Minette, Alnoite, Camptonite, Monchiquite, Fourchite, Vogesite, Appinite and Spessartite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Serpentinite and Minette is white, greenish white or grey. The specific heat capacity of Serpentinite is 0.95 kJ/Kg K and that of Minette 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 Minette is heat resistant, impact resistant.
