Bertibubba Supersuite (c. 1965-1945 Ma; older name Wooramel Suite). Leucocratic augengneiss with strong subvertical planar fabric and gently E-plunging stretching lineation. Dominant D1-deformation, the first phase of the Errabiddy shear zone deformation, related to the Glenburg Orogeny. The gneiss is supposed to be derived from partial melting of rocks like those of the Dalgaringa supersuite; it shows a strong EW foliation, and good dextral shear sense indicators on horizontal surfaces. Weakly deformed pegmatite veins probably belong to the Moorarie granites (1830-1780 Ma)
