Rock Fragmentation and Particle Size in Crushed Zones

The size distribution of fragments in the crushed zone adjacent to a fault, and that of grains in a zone of very fine- grained particles (the fault gouge), was determined for two different faults in central Japan. One fault has a wide (ca. 100 m) zone of rock fragmentation between the fault gouge zone and the basement rock formation.
