Minerals Alert December 2011

A monthly online newsletter with product news, data releases and projects relating to the minerals and energy exploration industry.

1. Release of interpreted processed seismic data for Capricorn Survey, Western Australia

The Capricorn deep crustal seismic survey was acquired in 2010 and extends from the Pilbara Craton, across the Capricorn Orogen, to the Yilgarn Craton in Western Australia. This survey was a collaborative project between AuScope, and the Geological Survey of Western Australia (GSWA) and Geoscience Australia. Funding came from AuScope Earth Imaging, Western Australia’s Exploration Incentive Scheme, which is funded under the Western Australian Royalties for Regions program, and Geoscience Australia’s Onshore Energy Security Program. The survey consists of three traverses with a total length of 581 kilometres. These seismic and gravity data aim to image the extent of the Archean crust beneath the Capricorn Orogeny and identify the relationship between the Pilbara Craton and the Yilgarn Craton.

The interpreted processed seismic data were released on 23 November at a Public Presentation Workshop in Perth, which was hosted by the GSWA. The data is available as a free download.

A preliminary edition of the workshop proceedings will be available shortly on the GSWA website.

2. Release of line locations of Onshore Energy Security Program Seismic Surveys

A Geographic Information System (GIS) Dataset of Onshore Energy Security Program Seismic Survey Common Depth Points line locations is now available as a free download.

To obtain more information on this seismic survey please contact Tanya Fomin, Section Leader Seismic Acquisition and Processing, phone +61 2 6249 9725 or email tanya.fomin@ga.gov.au.

3. Release of the National Geochemical Survey of Australia Catchment Polygons

The National Geochemical Survey of Australia (NGSA) Catchment Polygons dataset has been released and is available as a free download. This dataset was created for the NGSA to help determine the location of target sites for sampling catchment outlet sediments in the lower reaches of defined river catchments. Each polygon represents a surface drainage catchment derived from a national scale 9 second (approximately 250m) resolution Digital Elevation Model.

For more information on this dataset please email patrice.decaritat@ga.gov.au or phone +61 2 6249 9378.

4. 6th International SHRIMP Workshop, 1-4 August 2012

The Geoscience Australia Geochronology Laboratory is hosting the 6th Biennial Sensitive High Resolution Ion MicroProbe (SHRIMP) Workshop in Queensland from 1-4 August 2012 to discuss, debate and celebrate all matters SHRIMP. The workshop will immediately precede the 34th International Geological Congress in Brisbane starting on 5 August 2012.

For more details on the workshop and to download the first circular, please go to the SHRIMP Workshop website.
