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.

A subset of the NSW water bore dataset focused specifically on Cobar.

Greyscale image of second vertical derivative (2VD) of total magnetic intensity reduced to the pole (TMI RTP). Darker tones indicate lower values and lighter tones represent higher values. Reduction to the pole filters magnetic anomalies to appear as if the Earth's magnetic field were locally vertical, as at the magnetic pole (assuming all magnetic sources are inductively magnetised). The 2VD filter shows the vertical rate of change in the first vertical derivative (1VD) of the Earth's total magnetic field and enhances boundaries and structural detail of shallow sources further than 1VD. The 2VD filter enhances magnetic textures in the image, however, it also amplifies non-geological noise. Variations in the magnetic field are caused by lithological factors, principally magnetite (and/or pyrrhotite) content. This Statewide image was generated by merging many individual airborne magnetic surveys.

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).

An index of 1:250 000 map sheets covering NSW. The index shows maps where the total statewide geophysics package has been clipped and re-imaged to enhance colour stretch for the local regions. Each map sheet suite contains grids and images for up to 40 different layers, including: - Total Magnetic Intensity (TMI) - TMI Reduced to the Pole (RTP) - First Vertical Derivative (1VD) of TMI RTP - Second Vertical Derivative (2VD) or TMI RTP - Tilt Angle Filter of TMI RTP - TMI RTP and TMI RTP Tilt composite - Analytical Signal (AS) of TMI RTP - 250m and 500m Upward Continuations (UC) of TMI RTP - 1VD of TMI RTP UC products - Potassium percentage (Kperc) - Thorium parts per million (Thppm) - Uranium parts per million (Uppm) - Potassium-Thorium-Uranium ternary (KThU) - Zero mean normalised Kperc - Zero mean normalised Thppm - Zero mean normalised Uppm - Dose Rate - Uranium squared divided by Thorium (U2/Th) - Thorium divided by Potassium (Th/K) - Uranium divided by Potassium (U/K) - Uranium divided by Thorium (U/Th) - Airborne & Ground Bouguer gravity - Airborne & Ground Bouguer gravity and TMI RTP Tilt composite - Airborne & Ground Bouguer gravity 1VD - Airborne & Ground Isostatic gravity - Airborne & Ground Isostatic gravity and TMI RTP Tilt composite - Airborne & Ground Isostatic gravity 1VD - Digital Elevation Model (DEM) - Terrain colour stretch - Pseudocolour colour stretch - Greyscale colour stretch

The petrophysics dataset contains petrophysical (rock physical properties) data acquired by the Geological Survey of NSW. It stores measurements of samples and mapping sites collected under the Field Observations database, including from drillholes. It currently covers the following techniques: mass properties, electrical, radiometric, seismic rock physics, magnetic susceptibility and magnetic remanence. It contains raw readings and calculated results, from field and laboratory environments. Vector and tensor magnetic properties (remanence and anisotropic magnetic susceptibility (AMS)) are oriented to in-situ (geographic) and fold-corrected (stratigraphic) co-ordinates 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.
