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

Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar

Formation

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

Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.
