Abstract/Summary

Because gypsum dissolves rapidly in flowing water the subsurface dissolution of Permian gypsum at Ripon results in severe subsidence. The pattern of subsidence and methods of propagation are similar to those which might result from mining. Breccia pipe propagation and bulking factors for Permian rocks are discussed. The implications both of gypsum dissolution and the forceful expansion of anhydrite by hydration in flooded gypsum mines are assessed. The removal of gypsum and possible subsidence caused by large-scale water abstraction and mine dewatering are also considered.
