Definition
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite
Teschenite is coarse- to fine-grained, dark-coloured intrusive igneous rock that usually occurs in sills, dikes and irregular masses and is always altered to some extent

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.
Teschenite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Know all about Oolite and Teschenite properties here. All properties of rocks are important as they define the type of rock and its application. Oolite belongs to Sedimentary Rocks while Teschenite belongs to Igneous Rocks.Texture of Oolite is Clastic or Non-Clastic whereas that of Teschenite is Phaneritic. Oolite appears Rounded and Rough and Teschenite appears Veined and Shiny. The luster of Oolite is pearly to shiny while that of Teschenite is not available. Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors whereas Teschenite is available in dark grey to black colors. The commercial uses of Oolite are creating artwork, jewelry, used in aquariums and that of Teschenite are cemetery markers, commemorative tablets, creating artwork, laboratory bench tops, jewelry, sea defence, tombstones.
