Figure F57. Demagnetization behavior of discrete samples from working halves of core sections. A. Sample 180-1118A-28R-7, 11-13 cm (472.21-472.23 mbsf). B. Sample 180-1118A-15R-2, 30-32 cm (340.85-340.87 mbsf). C. Sample 180-1118A-20R-5, 83-85 cm (393.88-393.90 mbsf). NRM = natural gamma ray; Div. = division; Jo = NRM intensity. (Continued on next page.)
