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

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.
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 Borolanite and Granulite
Here you can know more about Borolanite and Granulite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Borolanite and Granulite 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 Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Borolanite vs Granulite, 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, Granulite is available in black, brown colors. Appearance of Borolanite is Banded and Foilated and that of Granulite is Veined or Pebbled. Properties of rock is another aspect for Borolanite vs Granulite. The hardness of Borolanite is 5.5-6 and that of Granulite is 6-7. The types of Borolanite are - whereas types of Granulite are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Borolanite and Granulite is white. The specific heat capacity of Borolanite 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.Borolanite is heat resistant, impact resistant, wear resistant whereas Granulite is heat resistant, wear resistant.
