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.

Isostatic residual Bouguer gravity image overlain on tilt-filtered total magnetic intensity reduced to the pole (Tilt TMI RTP) image. The image is a partially-transparent pseudocolour layer of Isostatic residual Bouguer gravity, with a histogram-equalised colour-stretch, overlain on a greyscale intensity layer of the Tilt TMI RTP, with a histogram-equalised stretch. Bouguer gravity compensates for variations in latitude, 'free-air' elevation and Bouguer correction (assuming a crustal density of 2.67 T/m³). The isostatic correction removes the effect of variations in the thickness of the Earth’s crust due to changes in topography. The tilt-angle filter of total magnetic intensity produces a local positive maximum over a magnetic source and is zero near the edge of the source, and is useful for tracing geological structure below variable depths of cover.

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 3D geoscience project aims to generate 3D models of lithological and structural aspects of basin and orogenic provinces at scales ranging from broad to site-specific. The models have applications in land-use management, civil engineering, water resource management, waste management, mineral and energy resource exploration and research.

This is the coal subset of the NSW drilling dataset available from Geoscientific Data Warehouse. The drillhole data has been compiled over time from various sources including mineral exploration reports and departmental records.It provides drill collar information for coal drillholes and associated data including classification of drilling purpose, drill type, licencee/driller information, date the hole was drilled, depth of hole drilled and references. This data is part of the New South Wales Geoscientific Data Warehouse (NSW GDW) series.

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).

AEM data has been reported to the NSW government and released under the requirements of the NSW Mining Act 1992. Contained within this vector file is the location of AEMsurveys and acquisition parameters.
