Figure F6. Geochemical composition of previously drilled gabbros and peridotites at slow-spreading ridges (note that, except for the Site 1275 troctolitic rocks, most primitive gabbroic rocks drilled so far have Mg# ~84, and there is a compositional gap between peridotitic Mg# and the gabbroic Mg#).
