Definition
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
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite

Archaeological Significance
Formation
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.
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 Teschenite and Oolite Properties
Know all about Teschenite and Oolite properties here. All properties of rocks are important as they define the type of rock and its application. Teschenite belongs to Igneous Rocks while Oolite belongs to Sedimentary Rocks.Texture of Teschenite is Phaneritic whereas that of Oolite is Clastic or Non-Clastic. Teschenite appears Veined and Shiny and Oolite appears Rounded and Rough. The luster of Teschenite is while that of Oolite is pearly to shiny. Teschenite is available in dark grey to black colors whereas Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors. The commercial uses of Teschenite are cemetery markers, commemorative tablets, creating artwork, laboratory bench tops, jewelry, sea defence, tombstones and that of Oolite are creating artwork, jewelry, used in aquariums.
