Archaeological Significance
Formation
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.
Jasperoid is a rare and peculiar type of metasomatic alteration of rocks. It is formed by extreme alteration of wall rocks within a shear zone which may occur in sediments, andesites, trachytes and basalts.

More about Granulite and Jasperoid
Here you can know more about Granulite and Jasperoid. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Jasperoid consists of mineral content and compound content. The mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz and mineral content of Jasperoid includes Clay Minerals, Pyrite, Quartz, Sulfides. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Jasperoid, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Jasperoid is available in black, brown, green, grey, pink, white colors. Appearance of Granulite is Veined or Pebbled and that of Jasperoid is Glassy or Pearly. Properties of rock is another aspect for Granulite vs Jasperoid. The hardness of Granulite is 6-7 and that of Jasperoid is 3.5-4. The types of Granulite are Metamorphic rock whereas types of Jasperoid are -. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granulite and Jasperoid is white. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Jasperoid is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Granulite is heat resistant, wear resistant whereas Jasperoid is heat resistant, pressure resistant, wear resistant.
