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

Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

Formation

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

Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.
