Palinspastic profiles across the Paraburdoo Hinge Zone, which forms the southwestern boundary to the Hamersley Shelf, indicate the existence of a fore-trough, adjacent to the Ashburton Trough, on the edge of the Hamersley Shelf. The fore-trough existed during Turee Creek Group and Lower Wyloo Group times of deposition and is characterized by unconformities or shallow-water facies on its margins. The distribution of mature iron-ores in the Hamersley Group suggests a relationship of this type of ore-body to the fore-trough margins. Continual uplift, or a gradual migration northeastwards of a geanticline, is suggested for the Ashburton Trough region from post-Hamersley Group times to pre-Ashburton Formation times of deposition. © 1982.
