Friction and mineral assemblage measurements from IODP subduction zone samples

DOI

We combine here the results of laboratory friction experiments and quantification of mineral assemblage for scientific drilling samples recovered from three particularly well-studied subduction zones: the Nankai Trough (SW Japan), Japan Trench (NE Japan), and Costa Rica. The manuscript Ikari et al., 2018 is a compilation of friction and mineral assemblage data for these three sites; reported here are measurements made at the University of Bremen. For this study, we conducted rotary shear tests, measuring the residual friction coefficients for disaggregated samples in a single-direct shear apparatus under effective stresses of 0.6-2.2 MPa and at a shearing rate of 0.3-7.5 µm/s. We also report mineral assemblages for our samples from X-ray diffraction (XRD) analyses.
