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

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