Definition
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite
Shoshonite is a basaltic rock, properly a potassic trachyandesite, composed of olivine, augite and plagioclase phenocrysts in a groundmass with calcic plagioclase and sanidine and some dark-colored volcanic glass

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.
Shoshonite 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.

All about Oolite and Shoshonite Properties
Know all about Oolite and Shoshonite properties here. All properties of rocks are important as they define the type of rock and its application. Oolite belongs to Sedimentary Rocks while Shoshonite belongs to Igneous Rocks.Texture of Oolite is Clastic or Non-Clastic whereas that of Shoshonite is Porphyritic. Oolite appears Rounded and Rough and Shoshonite appears Dull. The luster of Oolite is pearly to shiny while that of Shoshonite is dull. Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors whereas Shoshonite is available in brown- black, dark brown colors. The commercial uses of Oolite are creating artwork, jewelry, used in aquariums and that of Shoshonite are cemetery markers, creating artwork.
