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.

Granodiorite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.

More about Pseudotachylite and Granodiorite

Here you can know more about Pseudotachylite and Granodiorite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pseudotachylite and Granodiorite consists of mineral content and compound content. The mineral content of Pseudotachylite includes Iron Oxides, Pyroxene, Quartz, Stishovite, Sulfides and mineral content of Granodiorite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Pseudotachylite vs Granodiorite, 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, Granodiorite is available in black, grey, orange, pink, white colors. Appearance of Pseudotachylite is Dull and Soft and that of Granodiorite is Veined or Pebbled. Properties of rock is another aspect for Pseudotachylite vs Granodiorite. The hardness of Pseudotachylite is 7 and that of Granodiorite is 6. The types of Pseudotachylite are Not Available whereas types of Granodiorite are Not Available. 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 Granodiorite is white. The specific heat capacity of Pseudotachylite is 0.92 kJ/Kg K and that of Granodiorite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Pseudotachylite is heat resistant whereas Granodiorite is heat resistant, wear resistant.
