Figure F74. Lower hemisphere equal-area stereographic projection of poles to alteration veins and brittle shear zones in Hole 1270B, measured in the core reference frame and rotated using the measured paleomagnetic declination back to a common orientation as described in "Structures in Peridotite and Gabbroic Intrusions," in "Mantle Upwelling, Melt Transport, and Igneous Crustal Accretion" in the "Leg 209 Summary" chapter. All samples have measured negative inclinations, assumed to be indicative of a reversed polarity at the time of magnetization.
