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

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.

Hydrogeochemistry is the sampling and analysis of water to test its chemical properties. The chemistry of bore water can provide clues to the properties of the underlying rocks it has flowed through. Hydrogeochemistry data provides useful information about the quality of groundwater and the processes affecting it. The data is useful for landholders and local government agencies in assessing groundwater resources and their suitability for human and animal consumption, and for industry, other government agencies and scientists to assist with targeting and assessment of natural resources in the earth’s crust. The hydrogeochemistry data presented here has been sourced from various entities including the Geological Survey of New South Wales (GSNSW), Water NSW, CSIRO, and Geoscience Australia (GA). GSNSW and GA collect hydrogeochemistry data on a project basis. CSIRO has curated a groundwater hydrochemistry dataset by collating and standardising data from most State and Territory lead water agencies. Data within NSW will be continually added to this dataset as it is collected or acquired by GSNSW in the future. The hydrogeochemistry dataset presented here includes the following data: • Field measurements and laboratory analyses, such as pH, electrical conductivity, and total dissolved solids (TDS, a measure of salinity) • Major and minor ions, such as sodium and calcium • Trace element metals and non-metals, such as gold, silver, copper and zinc • Stable and radioactive isotopes, such as oxygen-18, carbon-14, and sulphur-34 In addition to this, CSIRO has calculated variables such as saturation indices, which are derived from the hydrochemistry measurements. Information for methodologies used by CSIRO, including the saturation indices, is available from the CSIRO Research Publications Repository.
