Figure F6. Diagrams of preparation of discrete cubic samples for paleomagnetic study, Expedition 329. A. Discrete sediment samples are first collected by inserting a subcorer into the split core (i.e., working-half core). The subcorer is then removed with sediment inside. Excess sediment from the base of the subcorer is trimmed with a spatula, and the rest of the sediment is extruded into the plastic sample box. B. Cubic sediment collected by the subcorer shown in A is placed in a plastic box with an arrow molded into its base. The internal volume of the cubic sample is 7 cm3. For hard rock samples (e.g., basalt), 8 cm3 of cubic sample is prepared by a cutting machine on the JOIDES Resolution.
