Figure F13. A. Magnetic susceptibility data for 0 to 160 mcd for Site 1211. The accurate correction factor for these raw instrument values is 0.68 x 10-5. Hole 1211B is offset from Hole 1211A by a constant (40 x 10-6). Hole 1211C is offset from Hole 1211A by a constant (80 x 10-6). B. GRA bulk density data for 0 to 160 mcd for Site 1211. Hole 1211B is offset from Hole 1211A by a constant (0.3 g/cm3). Hole 1211C is offset from Hole 1211A by a constant (0.6 g/cm3).
