The NSW Government has acquired hyperspectral data to aid geological interpretation. The location of hyperspectral coverage is contained within this layer. The information contained in this publication is based on knowledge and understanding at time of writing (April 2017). Because of advances in knowledge, users are reminded of the need to ensure that information upon which they rely is up to date. The information contained in this publication may not be or may no longer be aligned with government policy nor does the publication indicate or imply government policy.

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 percentage of potassium (K%) in the upper 20 centimetres of the ground. Cooler colours indicate lower abundances of potassium and warmer colours represent higher abundances. Variations in potassium values are caused by varied mineral compositions in host rocks and soils. This statewide image was generated by merging many individual airborne radiometric surveys.

AEM data has been acquired by the NSW government through NSW Exploration, Discovery 2000 and New Frontiers Initiative funding. Contained within this vector file is the location of AEMsurveys and acquisition parameters. The information contained in this publication is based on knowledge and understanding at time of writing (February 2017). Because of advances in knowledge, users are reminded of the need to ensure that information upon which they rely is up to date. The information contained in this publication may not be or may no longer be aligned with government policy nor does the publication indicate or imply government policy.

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.

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.

In 2023, the Geological Survey of NSW (GSNSW) engaged Geognostics to perform a review and update of the previous OZ SEEBASE 2021. Previous SEEBASE® studies of NSW basins undertaken by Frogtech Geoscience were undertaken over 15 years ago, and significant new data have been acquired since that time (drillholes, gravity, magnetics, seismic, etc.), along with on-going research and consolidation of statewide interpretations undertaken by the Geological Survey of NSW (GSNSW; i.e., the Seamless Geology Map of NSW by Colquhoun et al., 2022).

Marine protected areas are parts of the NSW marine estate managed to conserve marine biodiversity and support marine science, recreation and education. The NSW system of marine protected areas includes: marine parks – six multiple use marine parks cover around one third (approximately 345,000 hectares) of the NSW marine estate aquatic reserves – 12 aquatic reserves cover around 2,000 hectares of the NSW marine estate national parks and nature reserves – include around 20,000 hectares of estuarine and oceanic habitats.

In 2016, the Geological Survey of NSW (GSNSW) published a state-wide depth to basement 3D model (Robinson 2016, 2017). Since then, new geological and geophysical data have been released and used for the construction of basin-scale 3D geological models for the southern Thomson Orogen and the Sydney, Gunnedah and Bowen basins (Davidson 2019; Oliveira and Davidson 2019; Oliveira et al. 2019). The basement topography under these regions was modelled using constraints from drillholes, seismic, Seamless Geology, magnetics and gravity data. The results have now been incorporated into the updated Statewide 3D Basement Elevation Model reported herein.
