Lithology N NRM (A/m) MS (× 10–5 SI)
Mean SD Mean SD
Basalt 96 0.34 1.21 324.2 0.76
Diabase 681 3.37 0.65 1806.7 0.54
Oxide gabbro 357 2.73 0.89 1032.4 0.75
Gabbro 2170 0.18 0.84 114.8 0.60
Olivine gabbro 1979 0.71 1.16 360.0 0.81
Troctolite 199 0.05 0.87 64.5 0.50

Notes: Mean = geometric mean with standard deviation (SD) given in log units. Natural remanent magnetization (NRM) values include core sections with residual flux counts. MS = magnetic susceptibility. N = number of samples. This table is also available in ASCII.
