Formation
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 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.

Oolite 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. Oolite vs Granulite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Oolite and Properties of Granulite. Learn more about Oolite vs Granulite in the next section. The interior uses of Oolite include Decorative aggregates, Flooring 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 Oolite and Granulite, they have various applications in construction industry. The uses of Oolite in construction industry include Cement manufacture, Cobblestones, Landscaping and that of Granulite include As dimension stone, Building houses or walls.
More about Oolite and Granulite
Here you can know more about Oolite and Granulite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oolite and Granulite consists of mineral content and compound content. The mineral content of Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt 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 Oolite vs Granulite, the texture, color and appearance plays an important role in determining the type of rock. Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors whereas, Granulite is available in black, brown colors. Appearance of Oolite is Rounded and Rough and that of Granulite is Veined or Pebbled. Properties of rock is another aspect for Oolite vs Granulite. The hardness of Oolite is 3-4 and that of Granulite is 6-7. The types of Oolite are Not Available whereas types of Granulite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Oolite and Granulite is white. The specific heat capacity of Oolite is Not Available 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.Oolite is heat resistant, wear resistant whereas Granulite is heat resistant, wear resistant.
