Introduction
This material includes the following information:
-
“temp_chem_mineral_microstructure.pdf”: Slip zone temperature estimation, XRD analysis method, chemical compositions of original gouge and melt, XRD plot and mineral composition of original gouge, back-scattered electron images of the polished thin section of gouge sample used in this study, X-ray element map of sheared gouge
(LN1), additional BSE images of microstructures (SN1 and LN2), and SE images showing the evidence of melting in experimental and natural clayey gouges
