Depth to the Mohorovičić discontinuity (Moho) interpreted and modelled by Geognostics with support from government and industry. The Moho surface is the boundary between the Earth's crust and the upper mantle. The depth to moho is a representation of the thickness of the Earth's Crust. This moho surface is derived from seismic, gravity and other geophysical datasets.

This layer shows the boundary of the AusLAMP NSW survey and the station locations. Data were acquired by a collaboration between GSNSW and Geoscience Australia. Data were used to create a 3D resistivity model of the crust from 10 km depth to 200 km depth.

Core library samples that have been scanned by the NSW Hylogger. The HyLogger system acquires information on rock, ore and alteration minerals in drillcore, chips and pulps that are often difficult or impossible for the human eye to interpret correctly. Reflected light from the samples is broken into hundreds of different wavelengths by several spectrometers, allowing the recognition of unique spectral signatures for each mineral. This technology is also used on cores from petroleum and carbon dioxide (CO2) geosequestration wells to obtain mineralogical data that may complement porosity and permeability studies. X-ray diffraction and X-ray fluorescence instruments are used for rapid characterisation of a wide range of geological materials and for validating HyLogger data. The GSNSW offers a number of HyLogger scanning services to industry and academia. Each service requires a level of investment by the client and offers different periods of confidentiality.

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

Basement terrane age interpreted by Geognostics with support from government, academia and industry. Geological age of Basement terrane age is interpreted from a combination of geological and geophysical datasets. Basement terrane age is important in a Geothermal studies as older terranes have lower heat potential.

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
