Definition
Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite

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.
Oolites form when layers of calcite are deposited around a sand grain or fossil piece and are rolled around in calm water, which makes them round.

Granulite vs Oolite 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. Granulite vs Oolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Granulite and Properties of Oolite. Learn more about Granulite vs Oolite in the next section. The interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads whereas the interior uses of Oolite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Granulite and Oolite, they have various applications in construction industry. The uses of Granulite in construction industry include As dimension stone, Building houses or walls and that of Oolite include Cement manufacture, Cobblestones, Landscaping.
More about Granulite and Oolite
Here you can know more about Granulite and Oolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Oolite 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 Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Oolite, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors. Appearance of Granulite is Veined or Pebbled and that of Oolite is Rounded and Rough. Properties of rock is another aspect for Granulite vs Oolite. The hardness of Granulite is 6-7 and that of Oolite is 3-4. The types of Granulite are Metamorphic rock whereas types of Oolite are Pisolitic Oolite and Oncolitic Oolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granulite and Oolite is white. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Oolite is 0.65 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 Oolite is heat resistant, wear resistant.
