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
It is a metamorphic magnesium rich rock because it is composed of the mineral talc

Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
Soapstone is a talc-schist, which is a type of metamorphic rock and it is largely composed of the mineral talc and is thus rich inmagnesium.
