Pseudocolour image of the percentage of potassium (K%) in the upper 20 centimetres of the ground. Cooler colours indicate lower abundances of potassium and warmer colours represent higher abundances. Variations in potassium values are caused by varied mineral compositions in host rocks and soils. This statewide image was generated by merging many individual airborne radiometric surveys.

The NSW Government has acquired hyperspectral data to aid geological interpretation. The location of hyperspectral coverage is contained within this layer. The information contained in this publication is based on knowledge and understanding at time of writing (April 2017). Because of advances in knowledge, users are reminded of the need to ensure that information upon which they rely is up to date. The information contained in this publication may not be or may no longer be aligned with government policy nor does the publication indicate or imply government policy.

This vector contains the flight lines from the MinEx Collaborative Research Centre (CRC) Cobar Airborne Electromagnetic (AEM) survey. This survey was a collaboration between the Geological Survey of NSW and Geoscience Australia

The Geological Survey of NSW developed a Seamless Geology of UTM Zone 56 during 2014 as part of a project to develop a seamless vector geology dataset of the best available geological mapping data covering the whole of NSW.The overarching aims of the Statewide Seamless Geology Project were to: (i) compile the different original scales, formats and rock unit naming conventions into a consistent, statewide format; (ii) edge-match the geology across existing map sheets; and (iii) interpret the basement geology under cover. The resulting geodatabase comprises a series of layers which include: (i) solid basement geology; (ii) cover rocks (defined as undeformed and unmetamorphosed); (iii) Mesozoic igneous rocks; and (iv) Cenozoic sedimentary and igneous rocks. The project was divided into 3 major stages corresponding to the UTM zones which divide New South Wales. This dataset includes the seamless geology layers from the NSW portion of UTM Zone 56 (ie.east of 150 degrees longitude to the coast).

Depth to the Mohorovičić discontinuity (Moho) interpreted and modelled by Geognostics with support from government and industry. The Moho surface is the boundary between the Earth's crust and the upper mantle. The depth to moho is a representation of the thickness of the Earth's Crust. This moho surface is derived from seismic, gravity and other geophysical datasets.

This vector contains the boundary of the MinEx Collaborative Research Centre (CRC) Cobar Airborne Electromagnetic (AEM) surveydivided into three areas. This division is based on the flight line spacing which varies from 2.5 to 5.0 km. This survey was a collaboration between the Geological Survey of NSW and Geoscience Australia.

This layer shows the boundary of the AusLAMP NSW survey and the station locations. Data were acquired by a collaboration between GSNSW and Geoscience Australia. Data were used to create a 3D resistivity model of the crust from 10 km depth to 200 km depth.

Identifies Mineral Claims Districts in the State of NSW as defined by Part 9, Division 1, Section 173 of the Mining Act 1992 No. 29. There are two current Mineral Claims Districts: Lightning Ridge Mineral Claims District, and White Cliffs Mineral Claims District.

Basement terrane age interpreted by Geognostics with support from government, academia and industry. Geological age of Basement terrane age is interpreted from a combination of geological and geophysical datasets. Basement terrane age is important in a Geothermal studies as older terranes have lower heat potential.
