Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Jadeitite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Jadeitite vs Pseudotachylite 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. Jadeitite vs Pseudotachylite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Jadeitite and Properties of Pseudotachylite. Learn more about Jadeitite vs Pseudotachylite in the next section. The interior uses of Jadeitite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Pseudotachylite include Decorative aggregates, Entryways and Interior decoration. Due to some exceptional properties of Jadeitite and Pseudotachylite, they have various applications in construction industry. The uses of Jadeitite in construction industry include As dimension stone, Cutting tool, Knives and that of Pseudotachylite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.
More about Jadeitite and Pseudotachylite
Here you can know more about Jadeitite and Pseudotachylite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jadeitite and Pseudotachylite consists of mineral content and compound content. The mineral content of Jadeitite 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 Jadeitite vs Pseudotachylite, the texture, color and appearance plays an important role in determining the type of rock. Jadeitite is available in black, brown, colourless, green, grey, white colors whereas, Pseudotachylite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Jadeitite is Rough and Dull and that of Pseudotachylite is Dull and Soft. Properties of rock is another aspect for Jadeitite vs Pseudotachylite. The hardness of Jadeitite is 3-5 and that of Pseudotachylite is 7. The types of Jadeitite are Not Available whereas types of Pseudotachylite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Jadeitite is white, greenish white or grey while that of Pseudotachylite is light to dark brown. The specific heat capacity of Jadeitite 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.Jadeitite is heat resistant, water resistant whereas Pseudotachylite is heat resistant.
