Summary: This report documents the composition of clay mineral assemblages from six sites along the Kumano transect of the Nankai Trough subduction zone offshore south-central Japan. Coring was completed during Expeditions 315 and 316 of the Integrated Ocean Drilling Program, as part of Stage 1 of the Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE). A total of 702 samples of hemipelagic mud and mudstone were analyzed by X-ray diffraction, using oriented aggregates of the clay-size fraction (<2 µm). Smectite varies the most among the clay-size constituents, ranging in relative abundance from 6% to 66%. On average, the expandability of illite/smectite mixed-layer clay is equal to 65%, and there are no progressive changes in clay mineral diagenesis over the depths sampled. We recognize a temporal pattern in composition that is consistent with what has been documented elsewhere across the Nankai subduction margin. The detrital clays shifted gradually from a smectite-rich assemblage during the late Miocene to more illite-chlorite-rich assemblages during the Pliocene and Pleistocene. Most of the compositional differences between lithostratigraphic units can be attributed to differences in their depositional ages.
