Figure F58. AF demagnetization results from a basalt sample (Sample 200-1224A-5X-1, 17 cm; 30.87 mbsf). The top left diagram shows the intensity variation with progressive demagnetization; the top right diagram shows vector endpoints on a vector demagnetization diagram (orthogonal projections, where open squares are inclination and solid squares are declination); the bottom right diagram is an enlargement of the region near the origin of the above diagram; and the bottom left diagram shows the magnetization directions on an equal-area projection (open squares = directions with negative inclinations).
