5 Formation
5.1 Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Pseudotachylite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
Mugearite forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.

More about Pseudotachylite and Mugearite

Here you can know more about Pseudotachylite and Mugearite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pseudotachylite and Mugearite consists of mineral content and compound content. The mineral content of Pseudotachylite includes Iron Oxides, Pyroxene, Quartz, Stishovite, Sulfides and mineral content of Mugearite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Pseudotachylite vs Mugearite, the texture, color and appearance plays an important role in determining the type of rock. Pseudotachylite is available in black, brown, colourless, green, grey, pink, white colors whereas, Mugearite is available in black, brown, light to dark grey colors. Appearance of Pseudotachylite is Dull and Soft and that of Mugearite is Dull and Soft. Properties of rock is another aspect for Pseudotachylite vs Mugearite. The hardness of Pseudotachylite is 7 and that of Mugearite is 6. The types of Pseudotachylite are Not Available whereas types of Mugearite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Pseudotachylite is light to dark brown while that of Mugearite is white to grey. The specific heat capacity of Pseudotachylite is 0.92 kJ/Kg K and that of Mugearite is 0.84 kJ/Kg K.
