Figure F19. Variation of observed spinel shape from visual core description and thin sections in dunite and harzburgite from Hole 1274A. V = vermicular, I = interstitial, E = equant. V + I = both vermicular and interstitial spinel occurs in the same interval. For comparison, the lithologic variation in Hole 1274A is shown in the right panel.
