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

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

More about Quartzite and Basaltic Trachyandesite
Here you can know more about Quartzite and Basaltic Trachyandesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Quartzite and Basaltic Trachyandesite consists of mineral content and compound content. The mineral content of Quartzite includes Chlorite, Epidote, Hematite, Kyanite, Magnetite, Muscovite or Illite, Quartz and mineral content of Basaltic Trachyandesite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Quartzite vs Basaltic Trachyandesite, the texture, color and appearance plays an important role in determining the type of rock. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas, Basaltic Trachyandesite is available in black, brown, light to dark grey colors. Appearance of Quartzite is Lustrous and that of Basaltic Trachyandesite is Dull and Soft. Properties of rock is another aspect for Quartzite vs Basaltic Trachyandesite. The hardness of Quartzite is 6-7 and that of Basaltic Trachyandesite is 6. The types of Quartzite are Orthoquartzite and Metaquartzite whereas types of Basaltic Trachyandesite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Quartzite is white while that of Basaltic Trachyandesite is white to grey. The specific heat capacity of Quartzite is 0.75 kJ/Kg K and that of Basaltic Trachyandesite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Basaltic Trachyandesite is heat resistant, pressure resistant, wear resistant.
