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.

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.
