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).

Pseudocolour image of the concentration of thorium in parts per million within in the upper 20 centimetres of the ground. Cooler colours indicate lower abundances of thorium and warmer colours represent higher abundances. Variations in thorium values are caused varied mineral compositions in host rocks and soils. This statewide image was generated by merging many individual airborne radiometric surveys.

Geophysics survey 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. These surveys use uncommon techniques.

The Geochemistry (Whole Rock) data set contains information about the chemistry of rocks sampled in New South Wales and held by the Geological Survey of NSW (GSNSW). The data has been captured from analyses conducted by the GSNSW and from other work including academic research & collaborative projects, mineral exploration reports and geoscientific publications. The database contains geochemical analyses on nearly 27,000 rock samples which have been collected from field work and drilling activities which date back to the nineteenth century. There are also a small number of assay & hydro-geochemical results. It is an important dataset as the whole rock analysis of rocks for major and trace elements allows classification of the lithology of a rock and provides insight into the conditions in which the rocks formed as well as their economic potential.

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.

Ground surveyed gravity 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 layer shows the boundaries of each airborne gravity survey acquired by the NSW Government. Details on the spacing and age of the gravity data within each project area are in the attributes.

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 isotope geochemistry database contains geochronology and geological process data managed by the Geological Survey of NSW (GSNSW). Isotopic systems / techniques are U/Pb, K/Ar, Ar/Ar, Rb/Sr, Pb/Pb, Re/Os, Sm/Nd, Lu/Hf and stable sulfur, carbon, oxygen and hydrogen. The database stores location and sample collection information, lithological description, analytical and interpretation information for geological samples in New South Wales. The database includes links to stratigraphic unit, mineral occurrence and drill hole data. Some fields are controlled by look up tables.

The petroleum drillholes dataset stores information about conventional petroleum wells within NSW. The dataset has been developed to record summary data on petroleum exploration and development drilling for holes drilled in New South Wales. The dataset contains summary information about each drillhole such as location, total depth, azimuth/dip, wireline logs, core availability and library location and DIGS references. This data is part of the New South Wales Geoscientific Data Warehouse (NSW GDW) series.
