Fig. 9From: Depth profile of frictional properties in the inner Nankai accretionary prism using cuttings from IODP Site C0002Relationship between a − b and A total clay mineral content and B smectite content. Red and blue circles indicate the results for velocity change from 3 to 33 μm/s and from 0.3 to 3 μm/s, respectively. Open circles, squares, and diamond indicate data from previous studies of the Nankai samples along the Kumano transect (Takahashi et al. 2014; Okuda et al. 2021; Bedford et al. 2021)Back to article page
