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