Definition

Aplite is a fine-grained granite composed mainly of feldspar and quartz

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

Formation

Aplites belong to intrusive igneous rocks which are mostly quart and alkali feldspar and are formed from residual eutectic granitic liquids and represent the final crystallization products of magma.

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