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
Breccia is a rock consisting of angular fragments of stones which are cemented by finer calcareous material

Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
Breccia is a clastic sedimentary rock which is composed of broken fragments of minerals or rock which are cemented together by a fine-grained matrix and it forms where broken, angular fragments of rock or mineral debris accumulate.

All about Boninite and Breccia Properties
Know all about Boninite and Breccia properties here. All properties of rocks are important as they define the type of rock and its application. Boninite belongs to Igneous Rocks while Breccia belongs to Sedimentary Rocks.Texture of Boninite is Aphanitic to Porphyritic whereas that of Breccia is Brecciated, Clastic. Boninite appears Dull and Soft and Breccia appears Layered, Banded, Veined and Shiny. The luster of Boninite is vitreous while that of Breccia is dull to pearly. Boninite is available in bluish - grey, brown, colourless, green, grey colors whereas Breccia is available in beige, black, blue, brown, buff, green, grey, orange, pink, purple, red, rust, 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 Breccia are creating artwork, gemstone, jewelry.
