Lherzolites contain over 60% olivine, and some clinopyroxene and orthopyroxene. Lherzolite is a major constituent of the mantle and the source of most basaltic magmas.
The picture above (under crossed polarizers) shows olivine (right side of picture), orthopyroxene (lower left) and clinopyroxene (upper left), with characteristic allotriomorphic-granular texture.
