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
Hyaloclastite is an aggregate of fine, glassy debris formed by the sudden contact of hot, coherent magma and cold water or water-saturated sediment

All about Boninite and Hyaloclastite Properties
Know all about Boninite and Hyaloclastite properties here. All properties of rocks are important as they define the type of rock and its application. Boninite and Hyaloclastite belong to Igneous Rocks.Texture of Boninite is Aphanitic to Porphyritic whereas that of Hyaloclastite is Pyroclastic. Boninite appears Dull and Soft and Hyaloclastite appears Dull. The luster of Boninite is vitreous while that of Hyaloclastite is dull and grainy. Boninite is available in bluish - grey, brown, colourless, green, grey colors whereas Hyaloclastite is available in brown, grey, yellow colors. The commercial uses of Boninite and Hyaloclastite are an oil and gas reservoir, cemetery markers, creating artwork, soil conditioner, source of magnesia (mgo).
