Goldfields 2013 gravity survey — final data
Final data from the regional ground gravity survey completed in December 2013 will be available from the GSWA website on Latest Geophysical Surveys. A total of 8115 new gravity observations were made on a 2.5 km grid. The release will include grids and images of a compilation of the new data merged with earlier data. 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.
Images and grids of preliminary data from the regional magnetic and radiometric survey at line spacing of 100 m completed in November 2013 will be available from the GSWA website on Latest Geophysical Surveys.
Note: This release will be upgraded to final data if these are available by this date.

Strange and ancient underwater life forms, an unsolved shipwreck mystery and the record left by mega-tsunamis that struck millennia ago are a few of the fascinating ingredients in a new book launched on 5 February 2014 by the Minister for Mines and Petroleum, Bill Marmion.
The Geology of Shark Bay is a labour of love and the culmination of about 50 years’ research by Geological Survey of Western Australia (GSWA) geologist and author Dr Phil Playford and a team of co-authors.
Speaking to invited guests during the launch at Mineral House, Mr Marmion said the book would be of worldwide interest, not only to geologists and other scientists, but also to members of the public.
Shark Bay’s living stromatolites featured in the book closely resemble the earth’s earliest life forms found billions of years ago during the pre-Cambrian period. They are renowned as the most extensive and diverse organisms of their kind found anywhere on earth. They were first discovered by Dr Playford in 1954 and were largely responsible for Shark Bay being listed as a World Heritage Area.
‘Also of major importance is the existence at Shark Bay, Barrow Island, Legendre Island, and along the Kimberley coast, of deposits formed by mega-tsunamis that struck the coast up to 5000 years ago,’ Mr Marmion said. They are among the largest tsunami deposits known anywhere on earth.
The Zuytdorp Cliffs form another striking feature of the geology of the area.
This precipitous line of cliffs — some 200 km long and up to 250 m high between Shark Bay and Kalbarri — is named after the Dutch East India Company’s ship Zuytdorp, which was wrecked at their feet in 1712.
‘Survivors were some of the first European inhabitants of Australia,’ Mr Marmion said.

Release of the Albany–Fraser Orogen Deep Crustal Seismic Reflection Survey preliminary migrated seismic line cross sections
(Survey L201, Albany–Fraser Orogen 2012)
The Albany–Fraser deep crustal seismic reflection survey was conducted across the southeastern margin of the Yilgarn Craton and the adjacent Albany–Fraser Orogen during April to June 2012, funded through the Western Australian Government's Royalties for Regions Exploration Incentive Scheme (EIS). Acquisition and processing has been managed by Geoscience Australia (GA) through the National Collaboration Framework. This activity, adding to a network of existing deep seismic traverses, improves the understanding of the crustal structure of Western Australia.
The objectives the Albany–Fraser Orogen seismic reflection survey was to:
The data to be released comprises the preliminary migrated seismic line cross sections of lines 12GA–AF1, 12GA–AF2 and 12GA–AF3 together with the seismic shot points and the common depth points (CDP) shown on the cross section images.
In 2013–14 deep crustal reflection seismic survey acquisition under EIS has continued with the completion of the Eucla–Gawler survey in collaboration with GA, Geological Survey of South Australia and AuScope. This line continued east from Haig at the end of 12GA–AF3 to Tarcoola in South Australia. GSWA is also planning an EIS-funded line across the Canning Basin linking the Pilbara and the Kimberley to be acquired in May and June 2014.
The Geological Survey of Western Australia (GSWA) offers FREE training in its databases and online systems. The training is in the form of a presentation with hands on interaction in most systems. Topics include:
The morning session will be a basic introduction of how to use all the programs. During the afternoon session, participants will be able to get more in-depth practice using the programs with their own examples, and get some one-on-one advice about individual issues. A hands-on demonstration of the MRT software for preparing drilling and sampling data in the correct format for submission to DMP is available on request.
The afternoon session assumes competent computer skills. You can attend one or both sessions.
