Description:
A suite of mylonites rich in white mica, taken from the Betic Movement Zone (Sierra Alhamilla, Spain) shows progressive grain refinement involving a two-stage recrystallization history. Stage one is isochemical and possibly works by nucleation and growth of new crystals at sites of fracture and dilatancy. Stage two is nonisochemical and may be driven by differences in strain energy and chemical free energy between the two phases. Deformation is probably governed by brittle fracture and diffusional mass transfer along grain boundaries and cracks. The two stages of recrystallization are thought to represent a single progressive episode of deformation under changing metamorphic conditions.
