Figure F23. Plots of variation with depth of the inclination of high unblocking temperature components of magnetization in discrete samples, Holes U1415J and U1415P. Data from Hole U1415J show a downhole change from an upper unit with downward-directed magnetization to a lower unit with upward-directed magnetization, suggesting sampling of blocks that have been inverted relative to each other. More extensive data from Hole U1415P allow definition of statistically different mean inclinations from petrologically defined Units I (Layered Series) and III (Troctolitic Series), again consistent with sampling of two blocks with independent rotation histories.
