Summary:Metastable crystal growth is common in metamorphic systems; petrographic textures need not show any evidence of non- equilibrium behaviour. The authors question whether reactions ever occur close to an equilibrium boundary. The necessity for P or T overstepping is also required by nucleation-rate theory. [R.A.H.]
