Bertibubba Supersuite (c. 1965-1945 Ma; older name Wooramel Suite). Leucocratic augengneiss with strong subvertical EW planar fabric, gently E-plunging stretching lineation and good dextral shear sense indicators on horizontal surfaces. Dominant D1, 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.
