A pyroxenite is an ultramafic rock composed mainly by clinopyroxene, orthopyroxene and in minor amount, olivine (less than 40%). Depending of the modal mineralogy, the can be subclassified as orthopyroxenite (90% or more of opx), clinopyroxenite (90% or more than cpx), websterite (10% or less of olivine) and olivine-websterite (10-40% of olivine). Because the composition of these mineral phases is highly variable, pyroxenites have a broad range of compositions, however, they usually tend to have more SiO2 than peridotites.
