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.

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 is the coal subset of the NSW drilling dataset available from Geoscientific Data Warehouse. The drillhole data has been compiled over time from various sources including mineral exploration reports and departmental records.It provides drill collar information for coal drillholes and associated data including classification of drilling purpose, drill type, licencee/driller information, date the hole was drilled, depth of hole drilled and references. This data is part of the New South Wales Geoscientific Data Warehouse (NSW GDW) series.

Identifies areas in the Lightning Ridge Mineral Claims District and White Cliffs Mineral Claims District where the Department has declared reserves over which mineral claims cannot be granted, or can only be granted provided that special conditions are met, as defined by Part 17, Division 2, Section 367 of the Mining Act 1992 No 29.

In 1994 the Lightning Ridge Mining Board determined that the title ‘Preserved Fields’ would be applied to older mining areas which would not be returned to their previous land use, adopting less strict rehabilitation standards.

Geothermal gradient model (2023) created by Geognostics with support from government and industry. The geothermal gradient describes how temperature increases with depth inside the Earth. It is expressed in degrees Celsius per kilometre (°C/km). The linear geothermal gradients are from the top of SEEBASE to the surface. These were calculated using the combined heat-flow contribution of multiple crustal heat sources including upper mantle, radiogenic upper crust, and sediment thickness. The highest calculated geothermal gradients are generally related to areas interpreted to be underlain by granitic intrusions in the basement. The composition and heat production characteristics of the granites are largely unconstrained by analyses

This map layer shows the locations of in-stream water monitoring stations used by coal mining companies to monitor water quality in the Upper Hunter catchment. This information is provided by the coal companies as part of the Upper Hunter Mining Dialogue in cooperation with NSW Minerals Council and the community. A different coloured symbol is used for each coal company.

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.

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 is a preliminary low-resolution, pseudocolour image of airborne acquired Bouguer gravity with a histogram-equalised colour stretch. Cooler colours indicate lower Bouguer gravity values and warmer colours represent higher values. Bouguer gravity compensates for variations in latitude, 'free-air' elevation and Bouguer correction (assuming a crustal density of 2.67 T/m³). This image shows airborne gravity data from a survey that is ongoing. The Department of Customer Service has contracted two experienced specialist companies to fly the airborne survey. Final data will be available in 2024 at a higher resolution. Preliminary data should not be used in geological interpretations.
