The periphery of the granite has been converted to mortar gneiss and mylonitegneiss/schist. The host rocks, where they are of a pelitic origin, have been transformed into foliated contact schists comprisingcordierite and andalusite. The intensity of shear shows a progressive diminution avvay from the periphery. The brittle-ductiledeformation is ascribed to the emplacement of the granite causing multistage developments of multidirectional cleavage, kingtype folding and shear pods that are observable in macroscopic and microscopic dimensions. The deformation is not attributed tolarge displacements, but is rather interpreted as the cumulative result of en echelon shearing.
