Figure F23. Demagnetization behavior of discrete samples from working halves of core sections. A. Hole 1110A. B. Hole 1110B. C. Hole 1111A. D. Hole 1111A. E. Hole 1112A. Vector plots: horizontal component = filled circles, vertical component = open circles. Stereonet plots: lower hemisphere = filled circles, upper hemisphere = open circles. NRM = natural remanent magnetization; Div. = division; Jo = NRM intensity.
