KUBICEK WHITAKER, AND HANNA NEKVASIL Department of Geosciences, Stony Brook University, Stony Brook, New York 11794-2100, U.S.A. ABSTRACT Experiments were conducted to determine whether the presence of graphite is required to produce the Fe-Ti-P-enrichment, silica-depletion trend seen in ferrobasalts and ferrodiorites/jotunites. A nomi- nally anhydrous Snake River Plain olivine tholeiite was crystallized at 9.3 kbar in Fe-Pt capsules; the composition of the Fe-Pt alloy was empirically chosen such that the charge neither lost nor gained iron. The results of these experiments and those of previous experiments conducted in graphite are strikingly similar: in both cases the residual liquids were depleted in silica and enriched in Fe, Ti, and P. We conclude that the presence of carbon is not essential for producing this distinctive trend. Keywords: Experimental petrology, tholeiite, crystal-liquid differentiation, phase equilibria al. (2007). Experiments in this study were conducted in Pt capsules that had been INTRODUCTION pre-soaked with Fe° foil to prevent net transfer of Fe between sample and capsule Ferrobasalts found in the Craters of the Moon lava Þ eld in the during the experiment. Fe-loss changes the bulk composition as well
