Definition
Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite

Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing 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 Boninite and Oolite Properties
Know all about Boninite and Oolite properties here. All properties of rocks are important as they define the type of rock and its application. Boninite belongs to Igneous Rocks while Oolite belongs to Sedimentary Rocks.Texture of Boninite is Aphanitic to Porphyritic whereas that of Oolite is Clastic or Non-Clastic. Boninite appears Dull and Soft and Oolite appears Rounded and Rough. The luster of Boninite is vitreous while that of Oolite is pearly to shiny. Boninite is available in bluish - grey, brown, colourless, green, grey colors whereas Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors. The commercial uses of Boninite are an oil and gas reservoir, cemetery markers, creating artwork, soil conditioner, source of magnesia (mgo) and that of Oolite are creating artwork, jewelry, used in aquariums.
