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.

Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.

More about Serpentinite and Dunite

Here you can know more about Serpentinite and Dunite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Dunite consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Dunite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Dunite, 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, Dunite is available in dark greenish - grey colors. Appearance of Serpentinite is Rough and Dull and that of Dunite is Rough and Shiny. Properties of rock is another aspect for Serpentinite vs Dunite. The hardness of Serpentinite is 3-5 and that of Dunite is 3.5-4. The types of Serpentinite are Jadeitite whereas types of Dunite are Dunite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Serpentinite and Dunite is white, greenish white or grey. The specific heat capacity of Serpentinite is 0.95 kJ/Kg K and that of Dunite is 1.25 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 Dunite is heat resistant, pressure resistant, wear resistant.
