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'.
Rhyodacite is an extrusive volcanic rock intermediate in composition between dacite and rhyolite

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.
Rhyodacite 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 Rhyodacite 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 Rhyodacite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Serpentinite and Properties of Rhyodacite. Learn more about Serpentinite vs Rhyodacite in the next section. The interior uses of Serpentinite include Decorative aggregates and Interior decoration whereas the interior uses of Rhyodacite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Serpentinite and Rhyodacite, 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 Rhyodacite include As dimension stone, Construction aggregate, For road aggregate, Landscaping.
More about Serpentinite and Rhyodacite
Here you can know more about Serpentinite and Rhyodacite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Rhyodacite consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Rhyodacite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Rhyodacite, 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, Rhyodacite is available in black to grey, dark greenish - grey colors. Appearance of Serpentinite is Rough and Dull and that of Rhyodacite is Skeletal. Properties of rock is another aspect for Serpentinite vs Rhyodacite. The hardness of Serpentinite is 3-5 and that of Rhyodacite is 5.5-6. The types of Serpentinite are Jadeitite whereas types of Rhyodacite are Intermediate volcanic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Serpentinite is white, greenish white or grey while that of Rhyodacite is black. The specific heat capacity of Serpentinite is 0.95 kJ/Kg K and that of Rhyodacite is 1.12 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 Rhyodacite is heat resistant.
