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'.
Foidolite is a rare type of coarse-grained intrusive igneous rock with a feldspathoid mineral content greater than 60%

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.
Foidolites is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Serpentinite vs Foidolite 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 Foidolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Serpentinite and Properties of Foidolite. Learn more about Serpentinite vs Foidolite in the next section. The interior uses of Serpentinite include Decorative aggregates and Interior decoration whereas the interior uses of Foidolite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Serpentinite and Foidolite, 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 Foidolite include As dimension stone, Cement manufacture, For road aggregate.
More about Serpentinite and Foidolite
Here you can know more about Serpentinite and Foidolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Foidolite consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Foidolite includes Amphibole, Biotite, Feldspar, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Foidolite, the texture, color and appearance plays an important role in determining the type of rock. Serpentinite is available in black, brown, green, grey, white colors whereas, Foidolite is available in black, brown, green, grey, pink, white colors. Appearance of Serpentinite is Rough and Dull and that of Foidolite is Dull. Properties of rock is another aspect for Serpentinite vs Foidolite. The hardness of Serpentinite is 3-5 and that of Foidolite is 1.5. The types of Serpentinite are Jadeitite whereas types of Foidolite are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Serpentinite and Foidolite is white, greenish white or grey. The specific heat capacity of Serpentinite is 0.95 kJ/Kg K and that of Foidolite is 0.79 kJ/Kg K. 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 Foidolite is heat resistant, wear resistant.
