Figure F37. Demagnetization behavior of characteristic samples from Hole U1362A. A. Unit 1 example having an inclination value close to that expected for this location. B. Example of a steep inclination from Unit 4, possibly reflecting a drill string overprint. C. Example of inclination scatter seen in Unit 6, possibly indicating more intense alteration. D. Example of a rare negative inclination from Unit 8. Red squares = inclination values, blue circles = declination values. Solid lines = principal component analyses without the origin, dashed lines = principal component analyses anchored to the origin. NRM = natural remanent magnetization.
