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.

More about Serpentinite and Pseudotachylite

Here you can know more about Serpentinite and Pseudotachylite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Pseudotachylite consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Pseudotachylite includes Iron Oxides, Pyroxene, Quartz, Stishovite, Sulfides. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Pseudotachylite, 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, Pseudotachylite is available in black, brown, green, grey, pink, white colors. Appearance of Serpentinite is Rough and Dull and that of Pseudotachylite is Dull and Soft. Properties of rock is another aspect for Serpentinite vs Pseudotachylite. The hardness of Serpentinite is 3-5 and that of Pseudotachylite is 7. The types of Serpentinite are Jadeitite whereas types of Pseudotachylite are Cataclastic 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 Pseudotachylite is light to dark brown. The specific heat capacity of Serpentinite is 0.95 kJ/Kg K and that of Pseudotachylite is 0.92 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 Pseudotachylite is heat resistant.
