Hornblende-granitoid with steep foliation and layering (trending E-W) and a subvertical stretching lineation (not visible), cut by D2-shear bands that indicate N-side up (N at right). Erabiddy shear zone. This face is normal to a foliation 169-68. A strong stretching lineation on this foliation (parallel to this rock face) is L 288-50. North side up. This is probably the second phase in activity of the Errabiddy shear zone which gave the steep lineations. Width of view 1m
