Figure F57. Lower hemisphere equal-area stereographic projection of poles to black serpentine-magnetite and composite green/black serpentine veins and brittle shear zones in Holes 1271A and 1271B. Measurements were rotated into a common orientation using the measured paleomagnetic azimuth as described in "Structures in Peridotite and Gabbroic Intrusions," in "Mantle Upwelling, Melt Transport, and Igneous Crustal Accretion" in the "Leg 209 Summary" chapter.
