Latite 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 Latite and Oolite Properties
Know all about Latite and Oolite properties here. All properties of rocks are important as they define the type of rock and its application. Latite belongs to Igneous Rocks while Oolite belongs to Sedimentary Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Oolite is Clastic or Non-Clastic. Latite appears Rough and Oolite appears Rounded and Rough. The luster of Latite is subvitreous to dull while that of Oolite is pearly to shiny. Latite 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 Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo) and that of Oolite are creating artwork, jewelry, used in aquariums.
