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

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

More about Granite and Oolite
Here you can know more about Granite and Oolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granite and Oolite consists of mineral content and compound content. The mineral content of Granite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz and mineral content of Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Igneous Rocks. When we have to compare Granite vs Oolite, the texture, color and appearance plays an important role in determining the type of rock. Granite is available in black, grey, orange, pink, white colors whereas, Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors. Appearance of Granite is Veined or Pebbled and that of Oolite is Rounded and Rough. Properties of rock is another aspect for Granite vs Oolite. The hardness of Granite is 6-7 and that of Oolite is 3-4. The types of Granite are Igneous Protolith Granite, Sedimentary Protolith Granite, Mantle Granite, Anorogenic Granite, Hybrid Granite, Granodiorite and Alkali Feldspar Granite whereas types of Oolite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granite and Oolite is white. The specific heat capacity of Granite is 0.79 kJ/Kg K and that of Oolite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Granite is heat resistant, wear resistant whereas Oolite is heat resistant, wear resistant.
