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.

All about Granulite and Oolite Properties
Know all about Granulite and Oolite properties here. All properties of rocks are important as they define the type of rock and its application. Granulite belongs to Metamorphic Rocks while Oolite belongs to Sedimentary Rocks.Texture of Granulite is Granoblastic whereas that of Oolite is Clastic or Non-Clastic. Granulite appears Veined or Pebbled and Oolite appears Rounded and Rough. The luster of Granulite is vitreous while that of Oolite is pearly to shiny. Granulite is available in black, brown colors whereas Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors. The commercial uses of Granulite are curling, gemstone, laboratory bench tops, soil conditioner, tombstones and that of Oolite are creating artwork, jewelry, used in aquariums.
