Figure F89. A-D. Magnetic susceptibility vs. bulk or grain density in peridotite and gabbro samples recovered at Sites 1268, 1270, 1271, 1274, and 1275. Shown for comparison are data from Legs 147 (Gillis, Mével, Allan, et al., 1993) and 153 (Cannat, Karson, Miller, et al., 1995) and data from the Josephine ophiolite (Toft et al., 1990) and the Oman ophiolite (B.
