The coal seam gas drillholes dataset stores information about CSG sites within NSW. The dataset has been developed to record summary data on CSG 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.

The NSW Seamless Geology Project was originally a five-year initiative of the Geological Survey of New South Wales which commenced in late 2013 and aimed to provide a statewide compilation of the best available digital geological mapping data in an internally consistent format. The overarching aims of the NSW 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. Due to the size of the project, the work was divided into UTM zones, starting in the east with Zone 56, then moving west to Zone 54, and finishing with Zone 55. The western half of Zone 55 was completed in 2018, after which the results were merged with the previously completed Zones to produce version 1 of the NSW Seamless Geology dataset. Completion of this stage saw the end of phase 1 of the Seamless Geology Project, but it is intended that the Seamless Geology dataset will be continually updated and refined as new digital geological mapping data becomes available. Updates to the Seamless Geology dataset generally occur on an annual basis. Version 2.6 is the 8th major update to the NSW Seamless Geology and was released in 2026. This release includes major remapping of the northern Rockley–Gulgong Volcanic Belt; a significant upgrade to the mapping of Broughton Island; significant updates to the Lachlan Orogen and Cenozoic Sedimentary Province in the Canbelego 1:100,000 map sheet area; and attribute updates, data additions, and minor error fixes to all layers. Murray Basin During editing for version 2.1 of the Seamless Geology, the Cenozoic Murray Basin of southwest NSW was divided into its constituent units (formation or group level), with particular emphasis on the Loxton Sands, an economically significant unit containing numerous heavy mineral sand placer deposits and a number of mines producing rutile, zircon, and ilmenite. The Murray Basin linework was edited to reconcile the data with mapping in the existing NSW Seamless Geology dataset. See the lineage section for further details.

Many airborne surveys have been acquired by the NSW government through the NSW Exploration, Discovery 2000 and New Frontiers Initiative funding. Others have been acquired jointly with Geoscience Australia (formerly AGSO). Contained within this vector file are details on each of the surveys and some acquisition parameters, which will help locate survey data stored digitally.

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.

This layer shows the boundaries of ground gravity surveys acquired by the NSW government. Details on the spacing and age of the gravity station within each project area are in the attributes. The information contained in this publication is based on knowledge and understanding at time of writing (April 2016). 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 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.
