Figure F17. A. Downhole variations in olivine forsterite content and plagioclase anorthite content for average and single-spot analyses of coexisting plagioclase and olivine grains in Hole 735B olivine gabbros (gabbro, olivine gabbro, and troctolitic gabbro). Individual analyses are shown as shaded dots. Analyses of all other rock types are excluded in order to examine the vertical stratigraphy of Hole 735B independent of the influence of late-stage melt migration and intrusion of the ferrogabbros and gabbronorites. B. Plot of the difference between mol% An and mol% Fo for coexisting olivine and plagioclase in Hole 735B olivine gabbros against the anorthite content of the plagioclase.
