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

Archaeological Significance
Formation
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.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

All about Breccia and Boninite Properties
Know all about Breccia and Boninite properties here. All properties of rocks are important as they define the type of rock and its application. Breccia belongs to Sedimentary Rocks while Boninite belongs to Igneous Rocks.Texture of Breccia is Brecciated, Clastic whereas that of Boninite is Aphanitic to Porphyritic. Breccia appears Layered, Banded, Veined and Shiny and Boninite appears Dull and Soft. The luster of Breccia is dull to pearly while that of Boninite is vitreous. Breccia is available in beige, black, blue, brown, buff, green, grey, orange, pink, purple, red, rust, white, yellow colors whereas Boninite is available in bluish - grey, brown, green, grey colors. The commercial uses of Breccia are creating artwork, gemstone, jewelry and that of Boninite are an oil and gas reservoir, cemetery markers, creating artwork, soil conditioner, source of magnesia (mgo).
