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.

Areas restricted from mining or exploration. Reserves emplaced by external agencies or authorities. If a lease application covers part or all of one of these areas, it must be referred to and approved by the agency which created the restriction.

Marine protected areas are parts of the NSW marine estate managed to conserve marine biodiversity and support marine science, recreation and education. The NSW system of marine protected areas includes: marine parks – six multiple use marine parks cover around one third (approximately 345,000 hectares) of the NSW marine estate aquatic reserves – 12 aquatic reserves cover around 2,000 hectares of the NSW marine estate national parks and nature reserves – include around 20,000 hectares of estuarine and oceanic habitats.

This data set is modified from the Australian Geological Provinces Database (Geoscience Australia) and contains descriptions and spatial extents of the fundamental geological elements of NSW. Province types include sedimentary basins, tectonic provinces such as cratons and orogens, igneous provinces, and metallogenic or mineral provinces. At its simplest, a province may describe a sedimentary basin and its fill (e.g. the Sydney Basin). However, provinces may also be defined by a complex history of tectonics, metamorphism, magmatism, or metallogenesis. Provinces outlines, including their subsurface extent, are compiled at around 1:1 million scale. Descriptions of the provinces include age and geological history, parent-child hierarchy, constituent stratigraphic units and relations to surrounding provinces.

Spatial data set showing Mining Divisions within New South Wales. Each Mining Division has a Mining Registrar. A title is considered to be within the Mining Division in which the most northeasterly portion of the title lies.

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
