Figure F79. Downhole index properties of (A) bulk density, (B) grain density, and (C) porosity, and (D) velocities at Site 1138. Velocities measured in the x, y, and z direction are represented by circles, triangles, and squares, respectively. Open symbols = measurements on split cores. Solid symbols = measurements on cut samples. Lithologic unit boundaries are shown on the right (see "Lithostratigraphy").
