Definition
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite
Granite is a very hard, granular, crystalline igneous rock which consists mainly of quartz, mica, and feldspar and is often used as building stone

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.
Granite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks

Oolite vs Granite 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 Granite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Oolite and Properties of Granite. Learn more about Oolite vs Granite in the next section. The interior uses of Oolite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Granite include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Oolite and Granite, they have various applications in construction industry. The uses of Oolite in construction industry include Cement manufacture, Cobblestones, Landscaping and that of Granite include As dimension stone.
More about Oolite and Granite
Here you can know more about Oolite and Granite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oolite and Granite consists of mineral content and compound content. The mineral content of Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt and mineral content of Granite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Oolite vs Granite, 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, Granite is available in black, grey, orange, pink, white colors. Appearance of Oolite is Rounded and Rough and that of Granite is Veined or Pebbled. Properties of rock is another aspect for Oolite vs Granite. The hardness of Oolite is 3-4 and that of Granite is 6-7. The types of Oolite are Not Available whereas types of Granite are Igneous Protolith Granite, Sedimentary Protolith Granite, Mantle Granite, Anorogenic Granite, Hybrid Granite, Granodiorite and Alkali Feldspar Granite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Oolite and Granite is white. The specific heat capacity of Oolite is Not Available and that of Granite is 0.79 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 Granite is heat resistant, wear resistant.
