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 Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Oolite and Granulite Reserves. Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite. Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Oolite vs Granulite information and Oolite vs Granulite characteristics in the upcoming sections.

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 Pisolitic Oolite and Oncolitic Oolite 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 Oolite and Granulite is white. The specific heat capacity of Oolite is 0.65 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.Oolite is heat resistant, wear resistant whereas Granulite is heat resistant, wear resistant.
