Figure F248. A–E. Examples of thermal demagnetization data illustrating multicomponent remanences from Hole U1309D (Expedition 304). For vector endpoint diagrams: open circles = projections of remanence onto north-south vertical plane, solid circles = projections of remanence onto horizontal plane. Arrows indicate the progressive removal of drilling-induced (blue arrows), normal polarity overprint (orange arrows), and high-temperature reversed polarity component (red arrows). Note that the sample shown in C has an additional reversed polarity overprint at lower temperatures (yellow arrow). The demagnetization data are also shown on the corresponding equal area projections, with insets showing the decay of the normalized remanence. For demagnetization data: solid circles = lower hemisphere, open circles = upper hemisphere. NRM = natural remanent magnetization.
