Brief description
In 1997, Geoscience Australia and the Tectonics Special Research Centre (TSRC) at the University of Western Australian (UWA) and Curtin University conducted a joint research project to image the crustal setting of the Hamersley Province of northern Western Australia. This joint research was aimed at investigating the shallow structure of the Hamersley Province, the regions deeper basement structure and in so doing, developing an understanding of the region's tectonics and possible fluid migration pathways. The project's objectives were to obtain a better understanding of sub-surface geology of the Hamersley Province at a regional scale and a mine scale and relate this to the area's iron-ore mineral system. In particular, the project's objectives were to provide more information on: 1. regional crustal thickness and major features, 2. stratigraphic architecture of the regions mineral system, 3. structural architecture of the mineral system, 4. timing and locations of fluid migration pathways. The seismic survey obtained 136 km of nominally moderate fold CMP (common midpoint) deep reflection seismic data along two transects over approximately 5 weeks of acquisition.

Lineage
Maintenance and Update Frequency: unknownHamersley Province, Western Australia. The two principal iron-ore mining companies operating in the area, BHP Iron Ore and Robe River Mining Co. Pty. Ltd., were asked to become involved in discussions regarding the proposed regional deep seismic traverse across the Hamersley Province. MERIWA (Minerals and Energy Research Institute
of Western Australia), a Western Australia state government funding agency was also asked to participate in the project. The project was accepted by MERIWA in early 1997 and given the MERIWA project number MERIWA 282.
