This report presents the results of laboratory measurements on discrete samples from Integrated Ocean Drilling Program Expeditions 315 and 316 of the complex drilling project Nankai Trough Seismogenic Zone Experiment. Anisotropies of P-wave velocity and magnetic susceptibility were measured on a common suite of samples to evaluate the potential of acoustic anisotropy as a tool for deformation studies. Whereas in-plane P-wave velocity directions provide ambiguous results, the associated anisotropy parameter appears exempt from lithologic artifacts, in contrast to anisotropy of magnetic susceptibility, and overall agreement between the fabric shape parameter values suggests further exploratory work.
