Definition
Basaltic Trachyandesite is an extrusive igneous rock which is a type of Basalt rock and is formed by the rapid cooling of basaltic lava exposed at or very near the Earth's surface
Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.

Formation
Basaltic Trachandesite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
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.

More about Basaltic Trachyandesite and Granulite
Here you can know more about Basaltic Trachyandesite and Granulite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basaltic Trachyandesite and Granulite consists of mineral content and compound content. The mineral content of Basaltic Trachyandesite includes Olivine, Plagioclase, Pyroxene and mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz. You can also check out the list of all . When we have to compare Basaltic Trachyandesite vs Granulite, the texture, color and appearance plays an important role in determining the type of rock. Basaltic Trachyandesite is available in black, brown, light to dark grey colors whereas, Granulite is available in black, brown colors. Appearance of Basaltic Trachyandesite is Dull and Soft and that of Granulite is Veined or Pebbled. Properties of rock is another aspect for Basaltic Trachyandesite vs Granulite. The hardness of Basaltic Trachyandesite is 6 and that of Granulite is 6-7. The types of Basaltic Trachyandesite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite whereas types of Granulite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Basaltic Trachyandesite is white to grey while that of Granulite is white. The specific heat capacity of Basaltic Trachyandesite is 0.84 kJ/Kg K and that of Granulite is 0.14 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Basaltic Trachyandesite is heat resistant, pressure resistant, wear resistant whereas Granulite is heat resistant, wear resistant.
