Archaeological Significance
Formation
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.
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 vs Granulite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Jasperoid vs Granulite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Jasperoid and Properties of Granulite. Learn more about Jasperoid vs Granulite in the next section. The interior uses of Jasperoid include Decorative aggregates, Floor tiles, Homes and Interior decoration whereas the interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Jasperoid and Granulite, they have various applications in construction industry. The uses of Jasperoid in construction industry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics, Serves as an oil and gas reservoir rock and that of Granulite include As dimension stone, Building houses or walls.
More about Jasperoid and Granulite
Here you can know more about Jasperoid and Granulite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jasperoid and Granulite consists of mineral content and compound content. The mineral content of Jasperoid includes Clay Minerals, Pyrite, Quartz, Sulfides 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 Sedimentary Rocks. When we have to compare Jasperoid vs Granulite, the texture, color and appearance plays an important role in determining the type of rock. Jasperoid is available in black, brown, green, grey, pink, white colors whereas, Granulite is available in black, brown colors. Appearance of Jasperoid is Glassy or Pearly and that of Granulite is Veined or Pebbled. Properties of rock is another aspect for Jasperoid vs Granulite. The hardness of Jasperoid is 3.5-4 and that of Granulite is 6-7. The types of Jasperoid 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 Jasperoid and Granulite is white. The specific heat capacity of Jasperoid is 0.92 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.Jasperoid is heat resistant, pressure resistant, wear resistant whereas Granulite is heat resistant, wear resistant.
