The quartz was observed to exhibit strong static fatigue, the mean fracture time 〈t〉 being related to stress σ, concentration of water CH,O, and temperature T by 〈t〉 = t0 CH2O−;α exp [(u′/RT) − κ′σ]. Microfracturing associated with crack growth and spalling occurred continuously during the experiments. No creep strains could be detected. The rate of microfracturing n followed the expression n = a0 CH2O α exp [(−u′/RT) + κ′σ]tγ. These and other results suggest that static fatigue of quartz is due to stress corrosion cracking. The most likely mechanism is a silica hydration reaction. Static fatigue is suggested as the mechanism of brittle creep of rocks and of time-dependent earthquake phenomena.
