    Shown diagram is the IUGS classification of ultramafic igneous rock (rocks containing less than 10% of felsic minerals). You will only use this diagram if the cumulative modal percentage of all felsic minerals is less than 10%. Peridotite: Ultramafic rocks with greater than 40% olivine. Wehrlite, Harzburgite, Dunite, Lherzolite are types of peridotite rocks. Wehrlite- Peridotite with significant clinopyroxene and very less orthopyroxene. Harzburgite- Peridotite with significant orthopyroxene and very less clinopyroxene Lherzolite- Peridotite with significant amount of orthopyroxene and clinopyroxene Dunite- Peridotite with greater than 90% olivine. Pyroxenite: Ultramafic rocks with less than 40% Olivine. Websterite, orthopyroxenite and clinopyroxenite are types of pyroxenite rocks. we have no facility of audio send above is the explanation please follow

    Audio attachment is not possible that's why I am explaining the diagram in text.

Pyroxenite: Ultramafic rocks with less than 40% Olivine. Websterite, orthopyroxenite and clinopyroxenite are types of pyroxenite rocks.
