Abstract

Modern, unconsolidated deep-sea sediments acquire a characteristic magnetization during and after deposition. Using results obtained with remanent and induction magnetometers, it is possible in some cases to determine and evaluate: (1) bottom-current flow direction; (2) relative bottom-current flow magnitude; (3) post-sedimentation disturbances such as compaction, biogenic activity, slumping, etc.; (4) factors controlling sediment movement, such as flocculation, and therefore mode of transport, bedload versus sediment suspension; and (5) magnetic grain sizes and therefore possible sediment sources. The magnetization of such sediments, then, provides an indirect indicator of deep-sea depositional processes. The methods are quick, easy, and indirectly testable. © 1980, All rights reserved.
