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'.
Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption

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.
Tuff is formed when large masses of ash and sand which are mixed with hot gases are ejected by a volcano and avalanche rapidly down its slopes.

Serpentinite vs Tuff 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 Tuff characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Serpentinite and Properties of Tuff. Learn more about Serpentinite vs Tuff in the next section. The interior uses of Serpentinite include Decorative aggregates and Interior decoration whereas the interior uses of Tuff include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Serpentinite and Tuff, 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 Tuff include Building houses or walls, Construction aggregate.
More about Serpentinite and Tuff
Here you can know more about Serpentinite and Tuff. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Tuff consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Tuff includes Calcite, Chlorite. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Tuff, 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, Tuff is available in brown, grey, yellow colors. Appearance of Serpentinite is Rough and Dull and that of Tuff is Dull, Vesicular and Foilated. Properties of rock is another aspect for Serpentinite vs Tuff. The hardness of Serpentinite is 3-5 and that of Tuff is 4-6. The types of Serpentinite are Jadeitite whereas types of Tuff are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff, Andesitic tuff and Ignimbrite.. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Serpentinite and Tuff is white, greenish white or grey. The specific heat capacity of Serpentinite is 0.95 kJ/Kg K and that of Tuff is 0.20 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 Tuff is heat resistant, impact resistant, pressure resistant, wear resistant.
