The Georgina-Arunta deep seismic reflection line (09GA-GA1) has provided an image of the entire crust in this part of central Australia. At a first approximation, beneath the Neoproterozoic-Devonian sedimentary basins, the crust can be divided into four distinct regions, namely, the Aileron, Irindina and Davenport Provinces, and the Ooratippra Seismic Province. Each of these regions is separated from each other by major, crustal-scale faults. The observed crustal architecture has implications for geodynamic models for the evolution of the region, implying amalgamation of these crustal blocks in the Paleoproterozoic and major shortening and basin inversion in the Paleozoic.

As part of initiatives by the Australian and Queensland Governments, four new seismic reflection lines and three corresponding magnetotelluric lines were acquired in 2007 over the Mt Isa, Georgetown and Charters Towers regions. These data, combined with existing multidisciplinary data, have provided new insights into the 3D architecture, geodynamics and economic potential of the North Queensland region.

This dataset is part of a digital geological map of the Granites-Tanami Block which Australian Geological Survey Organisation has prepared by joining together as a seamless coverage 15 of the 1:250 000 geological maps which cover the province.The data layers in the digital map include geology, faults, lineaments structural data, mineral deposits and Australian Geological Survey Organisation drill hole locations. The digital data is available in Arcinfo/ Arcview or Mapinfo format. Topographic and cultural layers are not included: these can be purchased separately from AUSLIG.
