Summary:From a study of a mylonite sequence in Lewisian gneiss, developed during the evolution of the Moine thrust zone, an evolutionary model is proposed involving the cyclic redistribution of deformation between different mineralogical domains. The flow pattern changes from a more continuous and distributed ductile deformation to a more localized deformation at lower T, characterized by the development of mica from the syntectonic breakdown of feldspar.
