The petrophysics dataset contains petrophysical (rock physical properties) data acquired by the Geological Survey of NSW. It stores measurements of samples and mapping sites collected under the Field Observations database, including from drillholes. It currently covers the following techniques: mass properties, electrical, radiometric, seismic rock physics, magnetic susceptibility and magnetic remanence. It contains raw readings and calculated results, from field and laboratory environments. Vector and tensor magnetic properties (remanence and anisotropic magnetic susceptibility (AMS)) are oriented to in-situ (geographic) and fold-corrected (stratigraphic) co-ordinates where sample and bedding orientation are known.

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.

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.

Geological Maps at the 1:100 000 scale for all of NSW. This data has been synthesised into the 1:1 500 000 scale map of NSW, which forms the base layer of Minview.

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 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 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.

Index of map sheets in NSW. Includes the 1:250 000, 1: 100 000 and 1: 25 000 geological maps. The MinView layer provides a link to the DIGS catalogue entry.

Seismic surveys acquired by NSW and Commonwealth Government Agencies and private companies.

This data set is modified from the Australian Geological Provinces Database (Geoscience Australia) and contains descriptions and spatial extents of the fundamental geological elements of NSW. Province types include sedimentary basins, tectonic provinces such as cratons and orogens, igneous provinces, and metallogenic or mineral provinces. At its simplest, a province may describe a sedimentary basin and its fill (e.g. the Sydney Basin). However, provinces may also be defined by a complex history of tectonics, metamorphism, magmatism, or metallogenesis. Provinces outlines, including their subsurface extent, are compiled at around 1:1 million scale. Descriptions of the provinces include age and geological history, parent-child hierarchy, constituent stratigraphic units and relations to surrounding provinces.

Represent areas where the Department has declared reserves over which titles cannot be granted, or can only be granted provided that special conditions are met. The layer outlines these areas, and the restrictions which apply to each of them.
