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.


Zone 54 Mineral Potential Mapping in NSW

The Zone 54 Curnamona Province and Delamerian–Thomson Orogen mineral potential mapping report and data package have been released. Four significant mineral systems were analysed in the Zone 54 mineral potential study: Broken Hill type Pb–Zn–Ag and iron-oxide copper–gold in the Curnamona Province and orogenic Au and volcanic-associated massive sulfide in the Delamerian–Thomson Orogen of the Koonenberry Belt. Spatial modelling experts Kenex Pty Ltd and GSNSW's Mineral Systems section used a weights-of-evidence approach, creating up to 132 predictive maps for each mineral system, and up to 14 maps for the final models. Data is being released as a mineral potential atlas which can now be downloaded through DIGS.

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.
