The magnetization acquisition processes in unconsolidated sediments have been long studied (e.g., Johnson et al., 1948; King, 1955; Granar, 1958). The early studies showed that magnetic minerals in the sediments align along the ambient magnetic field during deposition through the water column. The magnetization resulting from the sedimentation process has been referred as depositional or detrital remanent magnetization (DRM). The magnetization acquisition process is still not well understood, and the role of the complex interplay of processes occurring during deposition, water‐sediment interface processes, burial, and compaction, etc., require further analyses. The characteristics and stability of the remanent magnetization of unconsolidated sediments are determined by the composition, grain size, and shape of individual grains. During deposition in aqueous media, the magnetic particles are subject to the aligning force of the ambient magnetic field, plus the gravitational and dynamic...
