Formation
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.
Trachyte is an igneous volcanic rock with an aphanitic to porphyritic texture. It is the volcanic equivalent of syenite rock and forms as a result of magmatic differentiation.

More about Granulite and Trachyte
Here you can know more about Granulite and Trachyte. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Trachyte consists of mineral content and compound content. The mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz and mineral content of Trachyte includes Augite, Biotite, Feldspar, Hornblade, Plagioclase, Quartz. You can also check out the list of all . When we have to compare Granulite vs Trachyte, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Trachyte is available in black, brown, dark greenish - grey, green, grey, light to dark grey, white colors. Appearance of Granulite is Veined or Pebbled and that of Trachyte is Banded. Properties of rock is another aspect for Granulite vs Trachyte. The hardness of Granulite is 6-7 and that of Trachyte is 6. The types of Granulite are Not Available whereas types of Trachyte are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granulite and Trachyte is white. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Trachyte is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Granulite is heat resistant, wear resistant whereas Trachyte is heat resistant, impact resistant, wear resistant.
