Definition
Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities
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'.

Formation
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
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.

Scoria vs Serpentinite 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. Scoria vs Serpentinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Scoria and Properties of Serpentinite. Learn more about Scoria vs Serpentinite in the next section. The interior uses of Scoria include Decorative aggregates and Interior decoration whereas the interior uses of Serpentinite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Scoria and Serpentinite, they have various applications in construction industry. The uses of Scoria in construction industry include Cement manufacture, Construction aggregate, For road aggregate, In landscaping and drainage works and that of Serpentinite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.
More about Scoria and Serpentinite
Here you can know more about Scoria and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Scoria and Serpentinite consists of mineral content and compound content. The mineral content of Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica and mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Scoria vs Serpentinite, the texture, color and appearance plays an important role in determining the type of rock. Scoria is available in black, brown, dark grey to black, red colors whereas, Serpentinite is available in black, brown, colourless, green, grey, white colors. Appearance of Scoria is Glassy and Vesicular and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Scoria vs Serpentinite. The hardness of Scoria is 5-6 and that of Serpentinite is 3-5. The types of Scoria are Not Available whereas types of Serpentinite are Jadeitite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Scoria is white while that of Serpentinite is white, greenish white or grey. The specific heat capacity of Scoria is Not Available and that of Serpentinite is 0.95 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Scoria is heat resistant, impact resistant, pressure resistant, wear resistant whereas Serpentinite is heat resistant.
