Data in support of "Fracture Mechanical Properties of Damaged and Hydrothermally Altered Rocks, Dixie Valley - Stillwater Fault Zone, Nevada, USA" by Owen A. Callahan, Peter Eichhubl, Jon E. Olson, and Nicholas C. Davatzes, submitted to Journal of Geophysical Research - Solid Earth. Supporting information includes: detailed description of X-ray diffraction methods and patterns; UCS test plug geometries, load curves, stress-strain conditions used to derive UCS and static elastic parameters; double-torsion specimen orientations, geometries, properties, and peak loads used to derive KIC, and load curves; and specimen orientations, geometries, properties, plateau loads, KIC*, and derived SCI from double-torsion load-relaxation tests with load curves. Filtering criteria, where applied, are discussed in the tables
