Definition
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.

Archaeological Significance
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.

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