Figure F13. Ni (ppm) versus Mg# (molar Mg/Mg+Fe) for gabbros, olivine gabbros, troctolites, orthopyroxene-bearing gabbros, oxide-oxide gabbros, ultramafic rocks, and peridotites from Site U1309. Shaded fields represent data from ODP Leg 153 (peridotite and gabbro = upper and lower purple shaded fields, respectively), ODP Leg 209 (peridotite and gabbro = upper and lower yellow shaded fields, respectively), and Hole 735B (green shaded field).
