Figure F75. Poles to planes in lower hemisphere equal-area stereo plots showing the orientation of spinel foliation, magmatic veins, lithologic contacts, and gabbro fabrics. The azimuthal orientation of features in individual pieces of the core was corrected to a common reference frame using paleomagnetic azimuth data (see "Structures in Peridotite and Gabbroic Intrusions," in "Mantle Upwelling, Melt Transport, and Igneous Crustal Accretion" in the "Leg 209 Summary" chapter). A. All data plotted and identified according to quality of the paleomagnetic measurements. No significant differences in the distribution of lower- and higher-quality data can be identified; all data are therefore plotted in B. B. Data set broken down by the type of feature measured. Assuming magnetic north is close to geographical north, magmatic veins and lithologic contacts form rough girdles rotated around a north–south axis. Magmatic veins tend to be more steeply dipping than lithologic contacts.
