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
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

Etymology
From its occurrence in the Izu-Bonin arc south of Japan
From Latin conglomeratus, to roll together, i.e. from com together + glomerare to gather into a ball, from glomus (genitive glomeris) a ball

Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

All about Boninite and Conglomerate Properties
Know all about Boninite and Conglomerate properties here. All properties of rocks are important as they define the type of rock and its application. Boninite belongs to Igneous Rocks while Conglomerate belongs to Sedimentary Rocks.Texture of Boninite is Aphanitic to Porphyritic whereas that of Conglomerate is Clastic. Boninite appears Dull and Soft and Conglomerate appears Shiny and Rounded. The luster of Boninite is vitreous while that of Conglomerate is dull. Boninite is available in bluish - grey, brown, colourless, green, grey colors whereas Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, 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 Conglomerate are cemetery markers, in aquifers, tombstones.
