Atlas of North Pilbara geology and geophysics - The Atlas of North Pilbara geology and geophysics: 1:1.5 million scale contains thematic maps of the north Pilbara Craton; themes covered include geology, geophysics (airborne magnetics, gamma-ray data, gravity), remotely sensed data and mineralisation.
  2. Hyperspectral mapping report - Hyperspectral Mapping of Mineral Assemblages Associated with Gold Mineralization in the Central Pilbara details results of an investigation into the use of airborne hyperspectral data (HyMap®) to aid detection of hydrothermal alteration assemblages associated with Archean lode gold deposits and epithermal gold systems in the central Pilbara region.
  3. Archaean tectonic processes report - The Archaean tectonic processes in the North Pilbara Granite-Greenstone Terrane report looks at the classic Pilbara dome and basin geometry with an alternative view point to that commonly presented.
