Esperance 2013 gravity survey — final data
Images Images and grids of final data from the regional ground gravity survey completed in September 2013 will be available from the GSWA website on the Latest Geophysical Surveys page at www.dmp.wa.gov.au/geophysics. A total of 7891 new gravity observations were made at 1 km spacing along roads in areas of urban and freehold land and on a 2.5 km grid by helicopter in open country.
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.
GGMplus gravity data compilation over Western Australia
GGMplus (Global Gravity Model +) is a composite of GRACE and GOCE satellite gravity, EGM2008 and short-wavelength topographic gravity effects at 200 m resolution for all terrestrial and near-coastal areas of the Earth between ±60° latitude. For details see the GGMplus website.
The GGMplus source data are distributed as a series of 5° x 5° tiles at a grid resolution of 0.002 degrees (7.2 arc-seconds). GSWA has compiled the 'free fall gravity acceleration' data from the eighteen 5° x 5° tiles that cover Western Australia into a single grid. By agreement with the authors of the GGMplus data, the compilation grid (in ER Mapper and Geosoft formats) is available for download from GSWA Geophysical Compilations.

Mineral Resources Bulletin 25, Gemstones of Western Australia, was first published with a ministerial launch in January of this year. Due to its popularity, the Geological Survey of Western Australia (GSWA) has reprinted further copies (in soft cover) which are now available for sale. In a collaborative arrangement between GSWA and the Gemmological Association of Australia (GAA), the authors have assembled a comprehensive resource on most gemstones and decorative stones used in jewellery and ornamental sculpture in the State. Although diamonds command pride of place among the industries of Western Australia, far less is known about occurrences of beryl, topaz, tourmaline, tektites, gem-quality quartz and associated siliceous gems. Material peculiar to this State, such as zebra stone, orbicular granite and mookaite are described, as are pearls, fossil wood, and precious metals.
Geographical locations are indicated where possible, and references are provided to earlier work. Gemstones of Western Australia is written not only for the professional geologist and gemmologist, but the book is also a valuable resource for the experienced fossicker and amateur rockhound.
The book is available to purchase from www.dmp.wa.gov.au/ebookshop at a cost of $50 (including GST). It is also available as a downloadable PDF.
Last database training date for 2013 — sign up now
You are invited to attend a free training session hosted by the Department of Mines and Petroleum to demonstrate current online systems. This is your opportunity to try these services for yourself and chat with the staff who create and manage them.
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 updated 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 overview of the use of all the programs. At the afternoon sessions, participants will be able to practise using the programs with their own actual examples and get some one-on-one advice about individual issues. You can attend one or both sessions.
