The petrophysics database contains petrophysical (rock physical properties) data managed and acquired by the Geological Survey of NSW (GSNSW). Petrophysical properties recorded are: magnetic susceptibility (volume normalised); principal axes and degree of anisotropy of magnetic susceptibility; natural remanent magnetisation (NRM) intensity and direction; remanent magnetisation component directions; Koenigsberger (Q) ratio; saturated density; dry density; grain density; porosity. Vector and tensor magnetic properties (remanence and AMS) are oriented to in-situ (geographic) and fold-corrected (stratigraphic) coordinates where sample and bedding orientation are known.

The Geological Survey of NSW developed a Seamless Geology of UTM Zone 56 during2014 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 Critical Mineral Analysis Project data set contains the analysis of a representative collection of the Geological Survey of New South Wales (GSNSW) existing rock and analytical powder collections to support the exploration for critical minerals. Existing pulps and powders from whole rock igneous rocks and mine dump samples were submitted for geochemical analysis to ensure the application of modern analytical techniques with significantly improved precision, detection limits for an extended range of trace elements, including the full complement of rare earth elements. Suites of mineral and rock samples from the Economic Rock and Mineral Collection were also selected for analysis from a variety of deposits, deposit types and regions across NSW. These comprise mineralised rocks and drillcore billets, and aggregates of ore minerals.

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.
