Syn-metamorphic and later brittle shear fabrics demonstrate sinistral offsets. (b) Plan view of amphibolite-grade shear fabrics. A sinistral sense of shear is indicated by geometry of the sigmoidal vein in the lower middle section of photograph. (c) Foliated microgranite at Locality 14.7B [NH 772 626] showing well-developed feldspar augen indicating sinistral shearing. (d) ? Shear banding within granite sheet at Locality 14.7B. Geometry of shear fabrics is highlighted in right-hand image and is suggestive of sinistral shear. (e) White foliated leucogranite at Locality 14.7C [NH 769 621] with sheared muscovite rich core and development of quartz&amp;feldspar augen where muscovite envelopes porphyroclasts. (f) ? Detail of leucogranite vein at Locality 14.7C. Geometry of synthetic shears within sheared core indicate dextral shearing. [Inset: Evidence of pressure solution (impacting of muscovite) in top left and bottom right quadrants implies dextral shear.] From: Fig. 14.5.Strachan, Rob et al. Editors. 2010.
