Figure F35. Comparison of FeO contents vs. An for plagioclase phenocrysts in abyssal tholeiites from the Indian Ocean (dots) and in gabbros of Hole 735B (diamonds). Data are from Dick et al. (Chap. 10, this volume) and J. Natland (unpubl. data). Solid lines give linear regressions through each group of data.
