Formerly undated sedimentary succession on the edge of the Pilbara Craton.
Zircon geochronology of tuffs constrains deposition of succession to c. 1320 Ma.
Sedimentation is coeval with intense tectonic activity in the Albany–Fraser and Musgrave Orogens.
Newly identified intracontinental basin was probably a far-field response to convergent margin tectonism.
