Data for "Weakening of Peridotite Sheared at Hydrothermal Conditions"

This data release comprises three separate datasets and their accompanying metadata, in zip files. The data were acquired as part of a laboratory study of the response of ultramafic materials to shear at hydrothermal conditions. The principal dataset consists of the strength-displacement data from 28 friction experiments acquired on gouges prepared from peridotite rock samples and from separates of its principal mineral constituents olivine and orthopyroxene. The other two datasets present mineralogical data for the run products obtained by X-ray diffraction (XRD) and energy dispersive system (EDS) techniques.
