Undeformed granite, probably Moorarie (ca 1830-1780 Ma). There are shear zones in the granite locally, but these have only vertical lineations, never horizontal ones; the horizontal lineations seem to be cut by the Moorarie granites. I therefore interpret the Moorarie suite to intrude during the first and second phases of activity on the Errabiddy shear zone
