Figure F2. Compressional wave velocity at 200 MPa is displayed as a function of saturated bulk density for selected cores from Hole 735B acquired during ODP Leg 176. Also shown are the lines of constant mean atomic weight (M), based on Birch's Law (Birch, 1961; Iturrino et al., 1991). As for the Hole 735B samples acquired during Leg 118, the olivine gabbros cluster near the line M = 21. Igneous lithology (Shipboard Scientific Party, 1999): o = olivine gabbro, + = gabbronorite, x = troctolitic gabbro.
