Figure F8. Relationship between Cr x 100/(Cr + Al) ratio (Cr#) of spinel and Fo of coexisting olivine in Holes 1271B, 1272A, and 1274A. The region labeled by OSMA indicates olivine-spinel mantle array of Arai (1994). Compositional fields for spinel at Hess Deep Site 895 are from Arai and Matsukage (1996). EPR = East Pacific Rise.
