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.

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.

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.

Many airborne magnetic/radioelement 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. Not all of these surveys have both radioelement and magnetic data.Some project areas have grids that have been merged from private exploration company data (that are open file). These are attributed as "private" exploration company data in the shapefile. The information contained in this publication is based on knowledge and understanding at time of writing (December 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.

Spatial data set showing Mining Divisions within New South Wales. Each Mining Division has a Mining Registrar. A title is considered to be within the Mining Division in which the most northeasterly portion of the title lies.

The Field Observations (FieldObs) database stores observations and measurements of rocks collected by the Geological Survey of NSW. Includes location information, stratigraphic unit, links to mineral occurrence and drill hole data, photo and sketch captions, structural measurements and observations, lithology and rock descriptions, sample collection information, and petrophysical measurements (magnetic susceptibility, radioelement and density).

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).

Areas restricted from mining or exploration. Reserves emplaced by external agencies or authorities. If a lease application covers part or all of one of these areas, it must be referred to and approved by the agency which created the restriction.

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

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.
