Abstract
Enhanced ductility is expected if deformation occurs during phase changes in minerals or during metamorphic reactions. Transformation-enhanced ductility largely arises from stresses generated by the transformation and may be an important consideration during mantle deformation. Reaction-enhanced ductility is a more complex process reflecting softening due to fluid release, increased diffusivities and the formation of small, strain-free grains. It is suggested that deformation should preferentially occur during the development of new minerals and may be inhibited by subsequent grain growth.This publication has 27 references indexed in Scilit:
