Pseudocolour image of the concentration of uranium in parts per million within in the upper 20 centimetres of the ground. Cooler colours indicate lower abundances of uranium and warmer colours represent higher abundances. Variations in uranium values are caused by varied mineral compositions in host rocks and soils. This statewide image was generated by merging many individual airborne radiometric surveys.

Depth contours derived from the NSW Basement Elevation Model.

Gazetted Reserves which exclude mining and/or exploration operations. Specifically for use in the Lightning Ridge and White Cliffs areas.

This vector contains the boundary and flight lines of Infill Area D. Infill Area D is part of the MinEx Collaborative Research Centre (CRC) Cobar Airborne Electromagnetic (AEM) survey. This survey was a collaboration between the Geological Survey of NSW (GSNSW) and Geoscience Australia. Infill D was funded by Legacy Minerals Pty. Ltd. Regional lines were funded by GSNSW.

The Competitive Allocation Pathway is designed to maximise the value of a suitable unallocated coal resource through a competitive process. The Department of Regional NSW’s (Regional NSW) Guideline for the Competitive Allocation of Coal (December 2020) sets out when the Competitive Allocation Pathway applies.

The petrophysics database contains petrophysical (rock physical properties) data managed and acquired by the Geological Survey of NSW (GSNSW). Petrophysical properties recorded are: magnetic susceptibility (volume normalised); principal axes and degree of anisotropy of magnetic susceptibility; natural remanent magnetisation (NRM) intensity and direction; remanent magnetisation component directions; Koenigsberger (Q) ratio; saturated density; dry density; grain density; porosity. Vector and tensor magnetic properties (remanence and AMS) are oriented to in-situ (geographic) and fold-corrected (stratigraphic) coordinates where sample and bedding orientation are known.

This vector file contains the location of reprocessed surveys and their acquisition parameters. These reprocessed surveys are from airborne geophysical surveys that have been submitted to the NSW government by exploration and mining companies. They have been publicly released under the NSW Mining Act 1992.

Gravity gradiometry data has been reported to the NSW government and released under the requirements of the NSW Mining Act 1992. Contained within this vector file is the location of surveys and acquisition parameters.

This layer shows a depth slice from a 3D resistivity model of the crust derived from an inversion of the AusLAMP NSW long period MT data.

This fossil database contains information on samples mainly collected by the Geological Survey of NSW unless otherwise noted, with many specimens housed at the Londonderry Core Facility. To ensure the preservation of of key outcrops, only localities for microfossils and trace fossils are shown. For information on the locality of macrofossils and/or where specimens can be inspected, please email geoinfo.admin@industry.nsw.gov.au.
