Basalt is a major component of the lunar soil and crust. The frictional properties, and thus the potential for seismicity and associated hazards on basaltic faults are significantly influenced by particle size distribution and normal stress conditions. We conducted velocity-stepping and slide-hold-slide shear experiments on simulated basalt gouges at gouge particle …
