Minerals Alert October 2012
A monthly online newsletter with product news, data releases and projects relating to the minerals and energy exploration industry.
- Geo-Region of the month – Mt Isa Inlier, northwest Queensland
- Seismic and magnetotelluric data released for Southern Carnarvon Survey in Western Australia
- Update on geophysical data releases
- About Minerals Alert
Each month Geoscience Australia will highlight a range of significant products relating to key Australian mineral provinces which have been released over the past 10 years and may be of interest to current explorers. This month’s Geo-Region is the Mount Isa Inlier, northwest Queensland. The highlighted products, which are available as a free download, are:
- Sequence stratigraphy - Measured sections and sequence stratigraphic interpretations: Surprise Creek Formation, Gunpowder Creek Formation, Torpedo Creek and Warrina Park Quartzites. This report and supporting images provide detailed measured sections of key sedimentary units within the Mount Isa Inlier that provide insights into the basin architecture and base metal mineral systems of this region.
- 3D basin architecture - 3D Basin Architecture and Mineral Systems in the Mt Isa Western Succession. This report from the Predictive Mineral Discovery CRC (pmd*CRC) presents and integrates sequence stratigraphy, structural analysis, geochronology, alteration mapping and numerical modelling in a 3D model of the Western Fold Belt of the Mount Isa Inlier.
- Deep Crustal Seismic Surveys - L180 Mt Isa Deep Crustal Seismic Survey, Queensland, 2006. Stacked and migrated data and images for lines 06GA-M1 to 06GA-M6. This data package includes gravity data, processed seismic data (SEG-Y format), TIFF images and associated metadata for six deep crustal seismic lines collected across the Mount Isa Inlier.
- Geophysical Modelling - Depth to Basement of northwest Queensland map. This map shows the depth of burial of basement geology beneath younger flat-lying cover material which is based on a compilation of point-located depth values and sourced from drill hole data, magnetic depth estimates and seismic refraction data.
- Energy Mineral Systems - An assessment of the uranium and geothermal potential of north Queensland. This report and associated maps document the uranium and geothermal energy potential of north Queensland using a geosystems approach to predict areas which are considered to have potential for five types of uranium mineral systems and two types of geothermal systems.

The Southern Carnarvon Survey was acquired in 2011 under Geoscience Australia’s Onshore Energy Security Program and in collaboration with the Geological Survey of Western Australia (GSWA) as part of the National Geoscience Agreement. Funding came from the Onshore Energy Security Program. The survey consists of a 260km line across the Byro Sub basin which is the onshore component of the Southern Carnarvon Basin, one of Australia’s most productive hydrocarbon provinces. The new data will expand scientific knowledge about potential water resources, geothermal sites and hydrocarbon and mineral resources in the area. The results also will help to improve the understanding of the Woodleigh Impact structure.
The processed SEG Y data, TIFF images and location information are available as a free download from the Seismic Acquisition and Processing Project.
Interpretations of the seismic sections and magnetotelluric models undertaken by GSWA and Geoscience Australia geologists will be released in February 2013 at a Public Workshop in Perth, Western Australia.
For further information please email email@example.com or phone +61 2 6249 9029.
Geoscience Australia will be managing the data acquisition program in New South Wales, Queensland, Western Australia and the Northern Territory.
The current status of Geoscience Australia's geophysical survey data acquisition is available in a comprehensive table.
To obtain further details on the survey acquisition, please email firstname.lastname@example.org or phone +61 2 6249 9229.
