Summary: We carried out anisotropy of magnetic susceptibility (AMS) measurements on samples from Integrated Ocean Drilling Program Sites C0004, C0006, C0007, and C0008 recovered during Expedition 316 to examine their magnetic fabrics. Magnetic susceptibility, Km , varied with lithology at each drilling site. Nondeformed sediments should show a positive shape parameter, T , indicating retention of their initial state of deposition and compaction. At Site C0004, the shape parameter reveals a scattered plot in the units of the megasplay fault zone and mass wasting deposits. A similar trend was observed in Unit I at Site C0007 in the prism toe, which also consists of mass wasting deposits. In contrast, the mass transport complex at Site C0008 has an enhanced compaction fabric. Despite the existence of many thrusts, the sediments at Sites C0006 and C0007 display a trend associated with compaction, with a drastic change in the orientation of magnetic fabric at the bottom of the holes. As a general implication, the sediments in this area obtained rather flattened fabrics at first and kept them, unless they were affected by later mechanical deformation. Due to tectonic disturbances in mass wasting deposits and the megasplay fault, deformed sediments/rocks are characterized by dispersed shape parameter values. Our results suggest that the AMS is potent to characterize mechanically disordered units in core samples and provides useful information for the onset of seismogenic behavior and locking of subduction thrusts.
