Figure F29. Plots of anisotropy of magnetic susceptibility vs. depth, Hole U1405A. Separation of eigenvalues is related to the shape and degree of the magnetic fabric (see “Paleomagnetism” in the “Methods” chapter [Norris et al., 2014a]). For example, if τ1 and τ2 are close or indistinguishable but distinct from τ3, then the bulk fabric is oblate. Lithostratigraphic units are described in “Lithostratigraphy.” Eigenvalues: τ1 = maximum, τ2 = intermediate, τ3 = minimum. V3 = minimum eigenvector, P = degree of anisotropy (τ1/ τ3). APC = advanced piston corer, XCB = extended core barrel.
