IMARC 2023
GSV booth at IMARC with Victorian banner and 3D theatrette

The International Mining and Resources Conference (IMARC) 2023 will be the largest resources conference ever held in the Asia Pacific, drawing delegates from nearly 100 countries. To be held from 31 October to 2 November, the conference is on track to not only break last year's delegate record of over 8000 people but also its record for the number of exhibitors and speakers.

The Geological Survey of Victoria (GSV) will have a large presence at IMARC. Geoscientists and other experts from both the GSV and Global Victoria will be on the Victorian Government pavilion to discuss Victoria’s geoscience program, minerals prospectivity and trade/investment support. A contingent of 14 Victorian mining equipment, technology and services companies will also have representatives on the pavilion.

Victorian IMARC presentations will focus on critical minerals development and hydrogen storage capacity as part of the renewable energy transition. The 3D geological theatrette will also be set up at the pavilion, providing an excellent opportunity for delegates to visualise Victoria’s geoscience data.

If you are attending IMARC 2023, please stop by the Victorian Government Pavilion J53 and say hello.

Resources Victoria launch

In July 2023 the Victorian Government established Resources Victoria, an overarching entity responsible for resources policy development and reform, regulatory approval coordination, the Geological Survey of Victoria and the Earth Resources Regulator.

Creating Resources Victoria signals the importance of both the minerals and quarry sectors in helping the state grow and transition. Resources Victoria will help drive increases in the mineral and quarry materials needed for a vibrant state-wide economy and support the construction sector, new infrastructure and the renewable energy transition.

Reforms will continue to help to strike the right balance between supporting the resources industry to grow while protecting the environment and local communities.

Darling-Curnamona-Delamerian project data release
Seismic survey trucks in regional Victoria

Regional geoscience is often a collaborative effort. The GSV is working with Geoscience Australia and the South Australia (SA) and New South Wales (NSW) geological surveys to interpret seismic data acquired as part of the Exploring for the Future (EFTF) Deep Seismic Acquisition for the Darling-Curnamona-Delamerian project.

The Victorian seismic data begins near Pinnaroo in SA and continues east to Swan Hill, passing south of Ouyen, and images the northern parts of the Stavely Arc and the Stawell Zone. Combined with the SA and NSW portions of the seismic profile, researchers hope the data will reveal the nature of the transition from the Adelaide Rift succession into the magmatic system of the Delamerian Orogen and the transition into the Lachlan Orogen.

Whole-rock geochemistry data collected from legacy drill holes for the Darling-Curnamona-Delamerian project has been released online. The data features new geochemistry for 720 rock samples that were collected from basement and cover in the Curnamona region and igneous samples from the Delamerian region. The GSV contributed 17 samples from 6 drill holes. More data from this project is expected later this year.

The whole-rock geochemistry data can be accessed via the Geoscience Australia Product Catalogue.

Eastern Victoria Geoscience Initiative update

The Eastern Victoria Geoscience Initiative aims to improve understanding of southeast Australia’s underlying geological architecture from the surface to approximately 60 kilometres deep within the Earth.

The Initiative includes the acquisition of fundamental geoscience datasets and applied geoscientific research. The findings will assist government to make better informed land management decisions to benefit the community, identify natural geological hazards, protect state infrastructure and manage earth resources.

Details of the project are available on the Resources Victoria website.

Southeast Lachlan ground gravity survey report released
The Southeast Lachlan ground gravity survey transect

The GSV has released the Southeast Lachlan Ground Gravity Survey 2019 report detailing the project background and area, data acquisition and processing of the gravity data. Gravity traverses were designed to test significant structural relationships and constrain geometries of geological units within the eastern Lachlan Fold Belt.

The report and associated data can be accessed via the GSV Catalogue.

The gravity data are also available through the Geoscience Australia Product Catalogue.

Shepparton-Numurkah regional ground gravity survey update

In August 2023, a ground gravity survey across the Victorian Riverine Plain between Seymour, Echuca and Wodonga commenced. Managed by the GSV and Geoscience Australia, and conducted by Daishsat Geodetic Surveys, the survey will acquire new data from approximately 20,000 new measuring points across the region. The survey will infill the existing ground gravity coverage to around 500 metres along public roads and tracks.

The survey crews have been making very good progress, however recent wet ground conditions are reducing survey efficiency and increasing the risk of road damage. Crews will take a short break to allow roads to dry out.

The survey is expected to be complete by early-2024. Survey data and reports will be freely available from GSV and Geoscience Australia’s digital platforms. For more information about the progress of the project please visit the project website.

Airborne gravity survey progress

A large-scale airborne gravity survey of a significant portion of Victoria has now passed the half-way mark. Sander Geophysics Ltd has been acquiring gravity data for just over 12 months, on behalf of the GSV, the Surveyor-General Victoria and Geoscience Australia. The planned collection area measures 147,000 km2, covering greater Melbourne and eastern Victoria as well as coastal, offshore and alpine areas.

The consistent and evenly distributed gravity measurements collected by the survey will have multiple uses, including improving height determination for GPS positioning and advancing the understanding of Victoria’s geological architecture and earth resource potential.

For more information about the progress of the project please visit the project website.

Rock, Paper, History - GSV collaboration with the Public Record Office Victoria
Historical geological cross-section from Kilcunda to Woolamai, and project archivists sorting through records at the Public Record Office Victoria

The GSV is working with the Public Record Office Victoria (PROV) to preserve a collection of historical geological records and make them accessible to the broader community. The collection comprises 170 years' worth of geological history and is an extensive record of the changing Victorian landscape above and below the surface.

The historical records were housed at the GSV Drill Core Library and are now located at PROV’s purpose-built archival-quality storage in North Melbourne. All records have been described by the project archivists and can be searched via the PROV Catalogue and viewed at the North Melbourne Reading Room. Digital copies of records can also be ordered.

Castlemaine Stonework Exhibition
Castlemaine Art Gallery and Museum entrance

The GSV has loaned several historical geological maps to a new art exhibition called Stonework at the Castlemaine Art Museum. The maps showcase the work of geologists and cartographers, who in the 19th century surveyed and mapped both the visible and the subterranean flows of rock and sediment in central Victoria.

The exhibition focusses on the many ways to look at stone and features work by Traditional Owners, contemporary artists, sculptors, photographers and jewellers. Works from the museum’s own collection by Louis Buvelot, Arthur Streeton, Frederick McCubbin, W. B. McInnes, Elma Roach and Penleigh Boyd show landscapes that are geologically dynamic, constantly weathering, warping, folding, eroding, erupting or sinking.

The GSV is delighted to be able to support the exhibition and promote the early work of the pioneers of the Survey, who laid the foundations for the geological evidence base we have today. The exhibition will run at the Castlemaine Art Museum from September 2023 to July 2024. More details are available at the Castlemaine Art Museum website.
