Perth Basin North 2011 airborne magnetic and radiometric survey — final data

Images and grids of final data from the regional magnetic and radiometric survey at line spacing of 400 m completed in December 2011 will be available from the GSWA website on the Latest Geophysical Surveys page at www.dmp.wa.gov.au/geophysics.

Point-located ('vector') data and grids from this survey can be purchased on disk from Geoscience Australia or downloaded free of charge from the Geophysical Archive Data Delivery System (GADDS).

Preliminary grids and images were released on 22 February 2012 and are available for download from www.dmp.wa.gov.au/14374.aspx

 

Latest Geophysics Program update

Access to previously released geophysical data

Image data from previous geophysical releases can be found on our Regional Geophysical Surveys page. Digital located and grid data can be purchased on media from Geoscience Australia or downloaded free of charge through the Geophysical Archive Data Delivery System (GADDS).

Training in GSWA databases and online systems

Attend a free training session hosted by the Department of Mines and Petroleum to demonstrate current online systems. The format is an interactive presentation which includes navigating the DMP website, searching for publications, finding mineral deposits using MINEDEX, finding digital datasets using the Data and Software Centre, open file mineral exploration reports using WAMEX, and bringing it all together with the interactive map viewer (GeoVIEW.WA). GeoMap.WA, a new GIS viewer for Windows, will also be demonstrated.

The morning sessions will be a high-level demonstration and overview of the use of all the programs. At the afternoon sessions, participants will be able to practise the programs using their own examples and get some one-on-one advice about individual issues. You can attend one or both sessions.

We take a maximum of 12 for the Perth session and 25 for the Kalgoorlie session for maximum comfortable learning for the participants.

Report 116 Provenance of the 1340–1270 Ma Ramarama Basin in the west Musgrave Province, central Australia

by Evins, PM, Kirkland CL, Wingate, MTD, Smithies, RH, Howard, HM, and Bodorkos, S

This report outlines the development of the Ramarama Basin of the west Musgrave Province.

The basin comprises calc-alkaline volcanic and intrusive rocks of the 1345–1293 Ma Wankanki Supersuite interleaved with paragneisses of the Wirku Metamorphics. The majority of the paragneisses had sedimentary precursors that were deposited between c. 1340 and 1300 Ma. Detrital zircon age spectra from samples of Wirku Metamorphics reveal younging trends within northwest-trending geographic/tectonic zones.

Dominant detrital zircon age components range from c. 1570 Ma in the northeast to c. 1520 Ma in the centre to c. 1330 Ma in the southwest. Detrital zircons with Archean ages similar to those in the Yilgarn Craton are present to the southeast.

The Ramarama Basin is interpreted as part of a calc-alkaline magmatic arc with compositional similarities to Andean-style continental arcs. Constraints from this study suggest development of the Ramarama Basin above a north-dipping subduction zone between the North and South Australian Cratons in the c. 1340 to 1300 Ma period.

The Report is now available.

34th IGC workshop — 3D mineral mapping from drill core to space

Workshop 22 is to be held at the 34th IGC in Brisbane 2012, entitled: 3D Mineral Mapping from drill core to space — Applications of VIRS technologies for mineral mapping and exploration, scheduled for 11 August 2012.

This course aims to provide the background theoretical spectral knowledge to improve skills for using hyper- and multispectral data for mineral mapping and exploration. The newly released Australian ASTER geoscience products, as well as airborne and drill core hyperspectral derived mineral mapping information will be presented and used in hands-on case studies for analysing hydrothermal alteration systems and targeting channel iron deposits.

More information about the short course can be found at www.34igc.org/workshops.php.

Please notice that there will be a closely related theme 32: Geoscience Information from Proximal and Remote Sensing Technologies. See www.34igc.org/scientific-themes-symposia.php for details.
