Definition
Borolanite is a variety of Nepheline Syenite and belongs to igneous rocks and contains nepheline-alkali feldspar pseudomorphs which occur as conspicuous white spots in the dark rock matrix
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

Orthoquartzite and Metaquartzite
Features
Application of acids on the surface causes cloudy frosting, Available in Lots of Colors and Patterns, Dissolves in hydrochloric acid, Is one of the oldest rock
Generally rough to touch, Is one of the oldest rock
Archaeological Significance
Formation
Borolanites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

More about Borolanite and Quartzite
Here you can know more about Borolanite and Quartzite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Borolanite and Quartzite consists of mineral content and compound content. The mineral content of Borolanite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite 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 Borolanite vs Quartzite, the texture, color and appearance plays an important role in determining the type of rock. Borolanite is available in brown, buff, cream, green, grey, pink, white colors whereas, Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. Appearance of Borolanite is Banded and Foilated and that of Quartzite is Lustrous. Properties of rock is another aspect for Borolanite vs Quartzite. The hardness of Borolanite is 5.5-6 and that of Quartzite is 6-7. The types of Borolanite are - whereas types of Quartzite are Orthoquartzite and Metaquartzite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Borolanite and Quartzite is white. The specific heat capacity of Borolanite 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.Borolanite is heat resistant, impact resistant, wear resistant whereas Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant.
