Sir Samuel — Throssell 2014 gravity survey — final data

Final data from the regional ground gravity survey (2.5 km grid) completed in September 2014 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 can be downloaded free of charge from the Geophysical Archive Data Delivery System (GADDS) or purchased on disk from Geoscience Australia.

DMP’s new eBookshop released

DMP’s new eBookshop releasedThe Department of Mines and Petroleum’s (DMP) eBookshop has been transformed and is now live. This replaces the existing eBookshop. The new updated eBookshop application is a completely new system, which is hosted by an external provider.

Although GSWA has produced almost 5000 products including books, maps and digital products, only maps, USB data packages, and nine premium publications are available to purchase in ‘hard’ format. A new online cart and payment system is in place. Records, Reports, Bulletins and other non-series books cannot be purchased in hard copy but are all available as PDFs to view and download from both the eBookshop and using the Geoscience publications tab accessed by the Online systems button on DMP’s Home page.

The new eBookshop interface is colourful, shows thumbnails of all products for easy navigation, and the landing page can be updated with new products for display.

The link from the DMP website to access eBookshop remains the same: www.dmp.wa.gov.au/ebookshop .

1:500 000 State interpreted bedrock geology of Western Australia, 2014

Base layer to provide more information for explorers

Base layer to provide more information for explorersA new Statewide seamless Interpreted Bedrock Geology digital map at a very useable 1:500 000 scale was released on 2 December by Mines and Petroleum Minister Bill Marmion.

The digital map will form the base layer for some Geological Survey of Western Australia (GSWA) maps and spatial products which will give explorers a consistent new summary of the geology of Western Australia. It is also the base layer for many of the Department of Mines and Petroleum’s (DMP) spatial databases.

The up-to-date framework will provide a more accurate backdrop for regional ground selection.

GSWA Executive Director Rick Rogerson said as well as being more accurate spatially, more information about each map unit is included than ever before.

‘This will provide a whole wealth of additional information which will be of great assistance to explorers and geologists,’ he said.

The 1:500 000 interpreted bedrock geology map is a complete reinterpretation and update based on GSWA mapping since 2000, the culmination of a decade’s work and understanding of the geology of Western Australia.

‘It is a set of intelligent spatial layers, rather than a single map and includes interpreted bedrock faults and folds, and areas of significant Cenozoic deposits, a separate layer of rocks less than 65 million years old,’ Dr Rogerson said.

‘The layers aim to illustrate the regional geological framework of Western Australia in as much detail as possible at this scale, rather than being simply a standalone map.’

The lookup table for the main interpreted bedrock geology layer is coarsely sorted using tectonic subdivisions first and then age, providing the digital equivalent of a map legend.

‘As well, the recent geophysical datasets acquired as part of the State Government’s Exploration Incentive Scheme (EIS) have been extensively used in generating the map,’ Dr Rogerson said.

Updates are already planned and will be released incrementally as more information becomes available.

Spatial layers at 1:2 500 000 scale, including geological polygons, structures and tectonic divisions, are the next product which will result in a new, completely revised State Geological Map — the first since 1998, and the first compiled entirely digitally.

At the launch, Minister Marmion said the map highlighted the State Government’s commitment to WA’s world-leading resource industry.

The 1:500 000 scale layers and associated lookup tables are available as a download from the Data and Software Centre.

Once there, go to Statewide Spatial Datasets, then Geology, then 1:500 000 Interpreted Bedrock Geology, then Download the product.

 

Christmas discount — Devonian Reef Complexes for $50!

Bulletin 145 Devonian Reef Complexes of the Canning Basin by Phillip E Playford, Roger M Hocking, and Anthony E Cockbain

The Devonian reef complexes form a spectacular belt of rugged limestone ranges that extend for 350 kilometres along the northern edge of Western Australia's Canning Basin. These complexes are regarded as the world's best example of an exposed ancient barrier reef system, and have become known as the Devonian Great Barrier Reef.

The rocks are prospective for both zinc-lead deposits and petroleum, and are regarded as a model for similar reefs that host prolific oilfields elsewhere in the world.
