Figure F244. Inclinations of magnetization components identified by principal component analysis of archive-half data as a function of volume susceptibility (measured on the AMST). Note that samples with steep positive inclinations correlate with intervals of high magnetic susceptibility, presumably reflecting the abundance of coarse multidomain magnetite. The green lines indicate the normal (+49°) and reversed (–49°) inclinations expected from a geocentric axial dipole.
