(a) Moderately dipping pre full crystallisation fabric in leucogranite
defined by alignment of feldspar and biotite crystals (pencil marks fabric orien-
tation). The fabric is subtle and shows no evidence for plastic deformation of the
grain shape fabric (e.g. kinking of biotite, grain size reduction in the plane of the
foliation). (b) Locally developed magmatic fabric in granite running parallel to
the long axis of a sheared mafic enclave.
