Redox equilibria and crystal chemistry of coexisting minerals from spinel lherzolite mantle xenoliths

The results of a Mossbauer spectroscopic study of olivine, spinel, orthopyroxene and clinopyroxene from spinel lherzolites from localities at Dish Hill and Cima, California, San Carlos, Arizona, Potrillo maar, New Mexico, and Al Kishb, Saudi Arabia, are reported.
