Magnetic images after subjecting the thin section sample to ARM with a DC field of 50 µT and an AC field of 80 mT. a Magnetic image of ARM in the +X direction. b Image in a overlaid on the optical scanner image. c Magnetic image of ARM in the −Z direction. d Image in c overlaid on the optical scanner image. Color scale represents the vertical magnetic field in nT (positive upward)
