Phase-1 and Phase-2 data release for area infill area RJ7 within the Rum Jungle AEM survey, 2010

Brief description

Airborne Electromagnetic data are being acquired by Geoscience Australia in areas considered to have potential for uranium or thorium mineralisation under the Australian Government's Onshore Energy Security Program (OESP). The surveys have been managed and interpreted by Geoscience Australia's Airborne Electromagnetic Acquisition and Interpretation project. In contrast to industry style deposit scale investigations, these surveys are designed to reveal new geological information at regional scale. The Pine Creek airborne electromagnetic survey comprised of three survey areas Woolner Granite, Rum Jungle and Kombolgie. Tempest data were acquired for Woolner Granite and Rum Jungle survey areas and are included in this report. Woolner Granite and Rum Jungle survey areas cover a total of 21 100 line km and an area of 43 200 km2. Phase-1 data, that is, contractor quality-controlled and quality-assessed data for Woolner Granite, Rum Jungle and Kombolgie, were released during 2009. Phase-2 data, that is Geoscience Australia layered earth inversion (GA-LEI) data and derived products for Woolner Granite and Rum Jungle, are included in this data release. The data and products described in this report are contained on the accompanying DVD. The Kombolgie survey data were acquired with VTEM. The VTEM Kombolgie inversion data and report will be included in a separate data release. The main products from the AEM surveys are conductivity depth slices and sections, conductance grids and an AEM Depth of Investigation grid. The data is provided in formats which can be viewed on most computers systems. They include, JPEG (.jpg) with associated world files for easy use in geographic information system (GIS) packages, ER Mapper grids (.ers), ESRI shape files (.shp) of the flight path, and point-located ASCII data with relevant metadata for derived products. This data product is for the infill area RJ7 only.

Statement: The AEM survey data were acquired and processed by the airborne geophysical survey contractors Fugro Airborne Surveys. Details on the acquisition and processing are available in Lawrence and Stenning (2009), which is included in the dataset. Phase 2 data - this data release is the result of the GA-LEI sample by sample inversion process and is documented in Costelloe 2010. References: Lawrence, M., and Stenning, L., 2009.
