Utah FORGE: Laboratory Shear Experiments Linking Fault Roughness, Friction, Permeability, and P-Wave Characteristics
This dataset contains results from five laboratory shear experiments on gneiss and granitoid samples from the Utah FORGE site, conducted at Penn State University. The experiments investigate links between fault surface roughness, frictional behavior, permeability, and P-wave acoustic properties during controlled shear deformation.
Data include mechanical and acoustic time-series measurements, rate-and-state friction model outputs, and roughness scans acquired using a Keyence optical profilometer. Mechanical parameters such as stress, displacement, friction, and permeability are provided alongside P-wave velocity, amplitude, and time-of-flight shifts. Roughness data are in .cag format, compatible with Keyence analysis software, and time-series and model data are in MATLAB .mat format. All variables and units are described in the accompanying README file.
