Post-depositional detrital remanent magnetism in reconstituted deep sea sediment

Kent, Dennis V.

Evidence of disturbance by benthic burrowing organisms is commonly observed in deep-sea sediment cores but these same cores often possess good magnetic records, especially of field reversals. The natural remanent magnetism (NRM) of these burrowed sediments cannot be a depositional detrital remanence (DRM) but must rather have been acquired at some later time. An experiment was designed to demonstrate that a post-depositional DRM could be acquired in deep-sea sediment in conjunction with sediment disturbance similar to that caused by benthic fauna.
