Figure F47. Hydrothermal alteration in Site 1272 and 1274 metaperidotites (estimated during visual core description) vs. density and magnetic susceptibility (measured as described in the "Physical Properties, in the "Explanatory Notes" chapter). Variations in these parameters, as well as data on seismic P-wave velocity and porosity, are moderately well correlated.
