    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).

    The New South Wales 1:1 500 000 scale geology has been compiled from numerous geological maps and regional geological synthesis datasets from the Geological Survey of New South Wales and Geoscience Australia. As part of a project to produce a surface geology map of Australia, Geoscience Australia (Liu et al. 2005) undertook substantial simplification and generalisation of these datasets to produce a seamless geology dataset of New South Wales at 1:1 000 000. This 1:1 000 000 geology dataset has been further simplified, generalised and updated by the Geological Survey of New South Wales to produce the present data set at 1:1 500 000

    Pseudocolour image of the ratio between uranium and potassium within the upper 20 centimetres of the ground. This image was generated using normalised input grids to avoid ‘divide by zero’ errors. Cooler colours indicate lower abundances of uranium relative to potassium and warmer colours represent the opposite. Variations in U/K ratio are caused varied mineral compositions in host rocks and soils. This statewide image was generated by merging many individual airborne radiometric surveys.

    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.

    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.

    Pseudocolour image of the ratio between uranium and thorium within the upper 20 centimetres of the ground. Cooler colours indicate lower abundances of uranium relative to thorium and warmer colours represent the opposite. Variations in U2/Th ratio are caused varied mineral compositions in host rocks and soils. This statewide image was generated by merging many individual airborne radiometric surveys.

    The Governor of NSW can create Mineral Allocation Areas (MAAs) for any mineral group under the Mining Regulation 2016. These areas prevent new exploration licence applications for the affected mineral group(s) in the area without Ministerial consent. Reporting and renewal requirements for existing mineral titles within each MAA are unaffected.

    Depth to the Lithosphere–Asthenosphere Boundary (LAB) modelled by Geognostics with support from government, academia and industry. The LAB surface is the base of the ridgid lithosphere and the top of the ductile asthenosphere. In geothermal terms it marks a thermal and mechanical tranisition in the Earth at a temperature of 1330 °C. This surface is modelled using themal modelling (mantle heat flow, crustal heat production, thermal conductivity, Moho depth and lithospheric structure) seismic tomography, magnetotellurics, global and regional geodynamic models and tectonic context.
