The new 1:50,000 map Geology of Warrumbungle National Park is now available for download and will be available for $11 from the national park and via mail. Based on mapping by the GSNSW and former Office of Environment and Heritage, it presents a new and detailed look at the rocks of Warrumbungle Volcano and its eruption history. On the back of the main map is an educational poster.


Yathong-Ivanhoe Trough Petroleum Data Package released

Previously known as two separate troughs, the Yathong Trough and Ivanhoe Trough have now been combined, based on revised interpretations and new data. The newly defined Yathong-Ivanhoe Trough within the Darling Basin is prospective for petroleum resources, but exploration to date has been limited in this trough. Recent interpretations and modelling using seismic data acquired after 2006, and modern petroleum systems knowledge, provide new exploration opportunities.

The new data package builds on the Darling Basin Data Package 2017, providing more focussed data and information about the Yathong-Ivanhoe Trough.

The Yathong‒Ivanhoe Trough Data Package 2020 assists potential explorers to readily access existing data and new interpretations, modelling and analysis. It includes:

  • a new report on the petroleum potential of the Yathong-Ivanhoe Trough
  • a comprehensive compilation of searchable reports in PDF (Adobe) format, that have also been bookmarked
  • databases and summary tables that enable a quick review and assessment of data
  • an IHS Kingdom® seismic project that includes new interpretations of major horizons
  • a 3D model of the trough (SKUA-GOCAD™) with major horizons modelled in time and depth domains
  • an ArcGIS (ESRI™) project and a QGIS project containing GIS spatial data.

The Yathong‒Ivanhoe Trough Data Package 2020 is available on a USB drive. Updated versions will be generated as new data and information are acquired. We are working towards online delivery of data packages.

New mineral resource projects map for NSW

Released in February 2020, the latest mineral resource projects map is available for free. This 1:1.5 million scale map includes operating coal, metallic and mineral sand mines, major industrial mineral operations, gemstone operations and districts, inactive mines, advanced projects, geologically significant deposits and infrastructure. Mineral deposit data was extracted from the NSW MetIndEx database in June 2019, with production based on royalties data.

A less detailed pocket-sized version at 1:3 million scale is also available for free.

MinView: major upgrade released

MinView is a public map viewer and data portal, provided by the Geological Survey of NSW to deliver free access to view, search and download a range of geoscientific data for NSW.

The rebuilt MinView portal was launched in mid-2017 and has been frequently updated since then.

However, the latest upgrade (Version 19.11.20 released on 21st November 2019), is the most significant change to the platform since mid-2017.

Some of the enhanced features in the new version include:

  • single-click queries.
  • a better map printing service.
  • quick title searches.
  • improved useability on mobile platforms.
  • new datasets.

There are now over 400 data sets that are now available for discovery and download including government geotechnical reports, company geophysical data and mineral potential mapping.

Perhaps the best feature of the new version is the backend upgrades resulting in faster rendering speeds.

Periodic table of mobile phones

The Geological Survey of NSW has released a great new teaching aid, focussing on metals found in mobile phones. It includes a map showing areas in NSW that produce, or have the potential to produce, some of these metals. There’s also a build-it-yourself mobile phone display sheet. Add your own mobile phone parts and learn about the metals in them!

Download the Periodic Table of Mobile Phones resource.

For more information about high-tech metals see our High-tech metal resources of NSW map.

Government geotechnical reports and data released

The Geological Survey of NSW is working with other NSW Government agencies to manage all government geotechnical reports and data for the state. GSNSW recently completed Phase 1 of this multi-year project by uploading around 3400 Public Works Advisory reports to a new geotechnical collection in DIGS® (found in the search tab in the header) and creating a new geotechnical report view in MinView (using Add view tab and selecting Geotechnical reports). More information on this project.

Seamless Geology of NSW

Version 1.1 of the New South Wales Statewide Seamless Geology dataset has been released and is available for free download in various GIS formats. This package represents the latest seamless statewide compilation of the best available NSW digital geology mapping.

A simplified format can also be used on smartphones and tablets using GSNSW-developed NSW Geology (iOS) and Locus (Android) applications. Download the new seamless mobile map at:

The NSW Seamless Geology Project was a five-year initiative of the GSNSW which commenced in late 2013. Version 1.1 represents the first update of the Seamless Geology dataset since the release of Version 1.0 in October 2018. It includes new data from the Thomson and Lachlan orogens, as well as updates to the attribution of faults and rock units.

Release of Coolabah and Mount Oxley explanatory notes

The Geological Survey of NSW has released the Coolabah and Mount Oxley explanatory notes, which are expected to be the last two standard map sheet explanatory notes to be published by the Geological Survey of NSW. They accompany the first editions of the Coolabah 1:100 000 geological map, which covers part of the central Lachlan Orogen, and the Mount Oxley 1:100 000 geological map, which covers a segment of the boundary between the central Lachlan Orogen and the southern Thomson Orogen.

With the creation of the NSW seamless geology dataset, future mapping will target specific issues and areas, rather than map sheets and all information will be updated through the digital database. These last two explanatory notes mark the end of an era of geological mapping of standard sheet areas that started in the mid-1960s in NSW.

NSW renewable energy resources map updated

MapAn updated NSW renewable energy resources map has been released. This map shows the sources of renewable energy in NSW – sunlight, wind, waves, biomass, water and heat from the Earth. It also shows small-scale solar and pumped hydro information and the renewable energy project pipeline. Renewable energy sources have been used by people for centuries to provide heat or mechanical energy. They will play an increasingly important role in electricity generation throughout the 21st century.

With exceptional renewable energy resources and world-class research and development institutions, NSW is particularly well-placed to take advantage of this growing industry.

3D model of major faults in the eastern Lachlan Orogen

The Geological Survey of NSW has released a 3D model of major faults in the eastern Lachlan Orogen using all available geological mapping, borehole and geophysical data.

The model is a powerful tool for studying the evolution of geology in NSW over the past 500 million years and gives a geological context for the location of major mineral resources.

High-tech metals map

This map shows areas in NSW that currently produce, or have the potential to produce, high-tech metals including copper and gold, rare earth elements (REEs), platinum group elements (PGEs), cobalt, lithium, titanium and zirconium.

The map also explains the sources and uses of high-tech metals, contains important project summaries, and provides charts of current world production and reserves.

High-tech metals are used in rapidly growing advanced-technology industries that are now being boosted by consumer demand for a high-tech, connected and environmentally sustainable future.


Central Lachlan Orogen mineral potential mapping project

The central Lachlan Orogen mineral potential mapping report and data package have been released. Three significant mineral systems were analysed in the central Lachlan Orogen mineral potential study: Granite-related Sn–W in the central Lachlan Orogen and Cobar Cu–Au and Cobar Pb–Zn systems of the Cobar Superbasin. Spatial modelling experts Kenex Pty Ltd and the GSNSW Mineral Systems section used a weights-of-evidence approach, creating up to 225 predictive maps for each mineral system, and up to 9 maps for the final models. Data is being released as a mineral potential atlas that can now be downloaded through DIGS.

Sydney-Gunnedah Basement project map

Sydney-Gunnedah 3D project model.

Sydney–Gunnedah 3D Model

Since 2014, Geological Survey of NSW has been using statewide geophysical imagery and other data, including drillholes, seismic sections and the seamless geology geodatabase, to interpret, map and model the 3D geology of NSW. The modelling program is developing a series of large-scale models, with a current focus on NSW sedimentary basins.

Recently the Sydney–Gunnedah 3D model was completed and a report published. The 3D geological model for the Sydney–Gunnedah Basin provides additional insight into the geology of the region and adds detail to the NSW depth to basement model.

It also delivers a geological framework for future detailed modelling, by highlighting regional and basin-scale features, mapping geological structures underneath the surface and describing the strata of rock types in areas with limited information.

The model highlights distinct changes in sea level and depositional environment, as well as the fault geometries and movements experienced by the basins.

For more information please visit our 3D project page, or follow these links to view the model or download the report (by following the link and typing Sydney–Gunnedah 3D model report into the search function).
