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.
Pyroxenites are ultramafic igneous rocks which are made up of minerals of the pyroxene group, such as augite and diopside, hypersthene, bronzite or enstatite.

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