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

Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay

Formation

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

Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
