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
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

Formation
Basaltic Trachandesite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

More about Basaltic Trachyandesite and Quartzite
Here you can know more about Basaltic Trachyandesite and Quartzite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basaltic Trachyandesite and Quartzite consists of mineral content and compound content. The mineral content of Basaltic Trachyandesite includes Olivine, Plagioclase, Pyroxene and mineral content of Quartzite includes Chlorite, Epidote, Hematite, Kyanite, Magnetite, Muscovite or Illite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Basaltic Trachyandesite vs Quartzite, 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, Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. Appearance of Basaltic Trachyandesite is Dull and Soft and that of Quartzite is Lustrous. Properties of rock is another aspect for Basaltic Trachyandesite vs Quartzite. The hardness of Basaltic Trachyandesite is 6 and that of Quartzite 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 Quartzite 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 Quartzite is white. The specific heat capacity of Basaltic Trachyandesite is 0.84 kJ/Kg K and that of Quartzite is 0.75 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 Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant.
