1 Definition
1.1 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
A ganister is a hard, fine-grained quartzose sandstone or orthoquartzite which is basically used in the manufacture of silica brick typically used to line furnaces and is a type of sedimentary rocks.
1.2 History

1.3 Etymology
From its occurrence in the Izu-Bonin arc south of Japan
From gan′is-ter i.e a hard, close-grained siliceous stone, often forming the stratum which underlies a coal-seam

5 Formation
5.1 Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.
