Figure F12. A. Magnetic susceptibility data for 0 to 115 mcd for Site 1212. The accurate correction factor for the raw instrument values is 0.68 x 10-6. Hole 1212B is offset from Hole 1212A by a constant (40 x 10-6). B. GRA bulk density data for 0 to 115 mcd for Site 1212. Hole 1212B is offset from Hole 1212A by a constant (0.3 g/cm3).
