Formation

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.  
Alkali fledspar granite 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 Alkali Feldspar Granite

Here you can know more about Pseudotachylite and Alkali Feldspar Granite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pseudotachylite and Alkali Feldspar Granite consists of mineral content and compound content. The mineral content of Pseudotachylite includes Iron Oxides, Pyroxene, Quartz, Stishovite, Sulfides and mineral content of Alkali Feldspar Granite 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 Alkali Feldspar Granite, the texture, color and appearance plays an important role in determining the type of rock. Pseudotachylite is available in black, brown, green, grey, pink, white colors whereas, Alkali Feldspar Granite is available in black, grey, orange, pink, white colors. Appearance of Pseudotachylite is Dull and Soft and that of Alkali Feldspar Granite is Veined or Pebbled. Properties of rock is another aspect for Pseudotachylite vs Alkali Feldspar Granite. The hardness of Pseudotachylite is 7 and that of Alkali Feldspar Granite is 6-7. The types of Pseudotachylite are Cataclastic rock whereas types of Alkali Feldspar Granite are Granite. 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 Alkali Feldspar Granite is white. The specific heat capacity of Pseudotachylite is 0.92 kJ/Kg K and that of Alkali Feldspar Granite 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 Alkali Feldspar Granite is heat resistant, wear resistant.
