Figure F13. Crystal fractionation and accumulation models for development of contrasting trends seen in lavas sampled during Leg 163X. Large symbols = flows, small symbols = clasts. The effects of accumulating pure plagioclase (Pl), 75% plagioclase and 25% olivine, 50% plagioclase and 50% olivine, and pure olivine (forsterite [Fo]60–80). The olivine composition in the mixed accumulation models are Fo68, as found in the flows. Large symbols = flows, small symbols = clasts.
