Airborne Electromagnetic (AEM) data are being acquired by Geoscience Australia (GA) in areas considered to have potential for uranium or thorium mineralisation under the Australian Government's Onshore Energy Security Program (OESP). The surveys, which are part of the Airborne Electromagnetic Acquisition and Interpretation project, are designed to reveal new information about geological regions, rather than deposit scale areas, by acquiring the AEM data at line spacings of between one and six kilometres over relatively large areas.

The Paterson AEM survey geological outcomes include mapping of subsurface geological features that are associated with unconformity-related, sandstone-hosted and palaeovalley-hosted uranium mineralisation. The data are also capable of interpretation for other commodities including metals and potable water as well as for landscape evolution studies. The improved understanding of the regional geology resulting from the Paterson survey results will be of considerable benefit to mining and mineral exploration companies.

Phase one data, that is, contractor quality-controlled and quality-assessed data, was released during 2009. Phase two data, that is Geoscience Australia layered earth inversion (GA LEI) data and derived products is included in this data release. The data described are presented on the DVD that accompanies this report.

The main products from the AEM survey are conductivity depth slices and sections, conductance grids, an AEM Depth Of Investigation grid and the interpreted basement anomaly map. The data is provided in formats which can be viewed by most computers and include JPEG (.jpg) with associated world files for easy use in geographic information system (GIS) packages. ER Mapper files (.ers) of grids, ESRI shape files (.shp) of flight path and ASCII data with relevant metadata are provided for derived products.

Data quality

Lineage:

The AEM survey data were acquired by the airborne geophysical survey contractors Fugro Airborne Surveys. The inversion data were processed and produced by the authors, and details are provided in the attached report.

Positional accuracy:

Positioning was via post-processed differential GPS methods. Horizontal positional accuracy of the data is approximately 1 metre (standard deviation).

Attribute accuracy:

The data have been acquired and processed to a standard of best practice as of the year 2008. More sophisticated processing algorithms may be applied to these data should they become available.

Logical Consistency:

Not applicable.

Completeness:

The dataset includes all final inversion data and products produced by Geoscience Australia for the Paterson AEM survey.
