Abstract | This peridotite is an interlayered sequence of spinel lherzolite and harzburgite; subordinate dunite occurs in layers and in 'dykes' and lenses. Pyroxenite and gabbroic dykes occur both crosscutting and occasionally parallel to the tectonite fabric; chromitite lenses or seams are associated with orthopyroxenite. Particular spinel forms are characteristic for each rock texture (coarse-granular, porphyroclastic, allotriomorphic-granular, cumulate, granoblastic, mortar); additionally, the chemistry of the spinel phases seems to more clearly reflect the Cr/Al ratio of the bulk rock and mineral phases than the Mg/Fe2+ ratio.
