*Lherzolite: An ultramafic plutonic rock, a type of peridotite, composed of 40-90% olivine with a subordinate percentage of orthopyroxene (typically a bright green, chromium-rich diopside) and a subordinate percentage of clinopyroxene (typically an iron-rich, black enstatite). It may contain minor minerals of the spinel group (chromite or spinel), garnet (pyrope), and calcic plagioclase.
