Figure 5. Plot of the characteristic remanent magnetization (inclination and declination) and normalized relative paleointensity vs. depth of the Brunhes-Matuyama transition at Hole 1020C. Solid circles = the u-channel measurements, open triangles = the results of the discrete samples. The agreement between ChRMs from u-channels and discrete samples is good during stable polarity intervals but becomes unsatisfactory during the reversal. Natural remanent magnetization (NRM) and anhysteretic remanent magnetization (ARM) were both AF demagnetized at 20 mT. Age model as in Figure 3. The dashed lines represent the values expected for an axial geocentric dipole field.
