Definition

Pyroxenite is a dark, greenish, granular intrusive igneous rock consisting mainly of pyroxenes and olivine

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

Formation

Pyroxenites are ultramafic igneous rocks which are made up of minerals of the pyroxene group, such as augite and diopside, hypersthene, bronzite or enstatite.

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