| Subsequent melting of mica pyroxenite may produce potassic magmas as a result of orogenic or extensional, thermal or bark triggers. |
| In similar contrast to the Okenyenya xenolith suite, lithologies such as wehrlite, eclogite and pyroxenite are also absent. |
| Chromite is a common minor constituent of basic igneous rocks of the peridotite and pyroxenite type. |
| Its lower part displays alternating bands of peridotite, pyroxenite, and dunite, but dunite is dominant throughout most of the unit. |
| The first group consists mostly of melagabbro, perkinite and pyroxenite. |
| The drilling also indicated that sulphides are regularly present in altered peridotite and pyroxenite gneisses underlying the mineralized laterite. |
