Mossman 1:250 000 topographic map

This map is part of the series that covers the whole of Australia at a scale of 1:250 000 (1cm on a map represents 2.5 km on the ground) and comprises 513 maps. This is the largest scale at which published topographic maps cover the entire continent. Each standard map covers an area of 1.5 degrees longitude by 1 degree latitude or about 150 kilometres from east to west and 110 kilometres from north to south. There are about 50 special maps in the series and these maps cover a non-standard area. Typically, where a map produced on standard sheet lines is largely ocean it is combined with its landward neighbour. These maps contain natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours (interval 50m), localities and some administrative boundaries. The topographic map and data index shows coverage of the sheets. Product Specifications Coverage: The series covers the whole of Australia with 513 maps. Currency: Ranges from 1995 to 2009. 95% of maps have a reliability date of 1994 or later. Coordinates: Geographical and either AMG or MGA (post-1993) Datum: AGD66, GDA94, AHD.

SA Gravity Survey 2002A4 (P200244), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 This SA Gravity Survey 2002A4 (P200244) contains a total of 651 point data values acquired at a spacing of 1000 metres. The data is located in SA and were acquired in 2002, under project No. 200244 for None.

A review of petroleum exploration and prospects in the Perth Basin

Petroleum exploration carried out in the Perth Basin up to August
1975 has been reviewed to provide a current assessment of knowledge of the
basin and to determine the need for future exploration.
The Perth Basin is in the form of a half-graben which developed
as a result of movement along the major Darling-Urella fault system which
forms the eastern boundary of the basin. It contains very large thicknesses
of post-Cambrian sediments known to include source, reservoir and cap rocks
suitable for petroleum accumulation. The tectonic forces which have moulded
the basin have been predominantly tensional and faulting is prevalent
throughout the basin.
A considerable amount of petroleum exploration has been done both
onshore and offshore and some commercially exploited gas fields have been
discovered onshore in the northern part of the basin. The prospectivity
of the basin varies from area to area, but overall it is regarded as fair.
There is considerable scope for future exploration, particularly offshore
where the number of wells drilled is small considering the large area
involved.

The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. .
 This Cobar P5009 Main reduced to pole fft 1st vertical derivative grid is the first vertical derivative of the TMI RTP grid of the Cobar Magnetic and Radiometric Survey, 2021 survey.
This grid has a cell size of 0.00039074 degrees (approximately 40m) , and given in units of nT per metre (nT/m).  The data used to produce the TMI grid was acquired in 2021 by the NSW Government, and consisted of 53617 line-kilometres of data at 200m line spacing and 60m terrain clearance. The data has had a variable reduction to the pole applied to centre the magnetic anomaly over the magnetised body. The VRTP processing followed a differential reduction to pole calculation up to 5th order polynomial. Magnetic inclination and declination were derived from the IGRF-11 geomagnetic reference model using a data representative date and elevation representative of the survey. A first vertical derivative was calculated by applying a fast Fourier transform (FFT) process to the TMI RTP grid of the Cobar Magnetic and Radiometric Survey, 2021 survey to produce this grid. This grid was calculated using an algorithm from the INTREPID Geophysics software package. This grid shows the magnetic response of subsurface features with contrasting magnetic susceptibilities. The grid can also be used to locate structural features such as dykes.

Exploring for the Future — Geological and hydrogeological investigations in the Western Davenport region: Northern Territory

This report presents key results from the Western Davenport study conducted as part of Exploring for the Future (EFTF), an Australian Government-funded geoscience data and information acquisition program.
The Western Davenport (WD)  investigation used existing geological and hydrogeological data and new AEM data to develop a 3D hydrostratigraphic model of the central part of the study area. This was augmented by existing and newly acquired hydrogeological and hydrochemistry data to improve the understanding of groundwater in the area. The collection and interpretation of these datasets have enabled a correlation between hydrostratigraphic units in the Wiso and Georgina basins in the WD area. The hydrochemistry data shows that the central zone of the WD is characterised by good-quality groundwater (&lt;1000 mg/L total dissolved solids), with the newly drilled bores identifying areas of low-salinity groundwater. These initial hydrochemistry results suggest groundwater in the WD could support irrigated agriculture.
The hydrochemistry data has identified three zones of potentially higher recharge. The groundwater stable isotope dataset suggests that there is minimal evaporation of water prior to recharge and that groundwater recharge only occurs following heavy rainfall events. This preliminary information suggests recharge to groundwater is dominated by episodic recharge from floodouts and creeks rather than direct infiltration across the WD area from large rainfall events. However, more data are needed to better define the role of floodouts in recharge to the groundwater system and to determine the contribution of creek beds versus floodouts to recharge.
Given the aridity of the area and the variable nature of recharge events, managed aquifer recharge could increase the security of groundwater resources in the area. The regolith mapping presented can assist in better understanding the surface and near-surface environments, and their influence on hydrogeological processes. This provides a tool with which to begin identifying potential areas for enhancing natural recharge processes to supplement existing groundwater resources. This mapping was possible because of the increasing availability of higher resolution digital elevation, airborne radiometric and Landsat satellite remotely sensed data.
The improved understanding of geology and hydrogeology, coupled with managed aquifer recharge mapping undertaken as part of the EFTF program, provides new information to support groundwater management in the WD area.

Saline seepage and land degradation - a New South Wales perspective

An overview is given of New South Wales saline seepage and resultant dryland salinisation, in the context of land degradation concerns across the Murray-Darling Basin.  Causes of saline water discharge, the extent of dryland salting in the State, and its effects on land and water resources are outlined. The problem is assessed in terms of present knowledge and action needed to prevent and / or control its spread. Research priorities are suggested. Both specific and broad strategies already addressing dryland salinisation and associated land degradation are described. Future actions for New South Wales are outlined and the need is stressed for community education, as well as 3-way cooperation between governments, scientists and landholders.

This record one in a series of reports detailing the geochemical and mineralogical results of sampling collected at mine waste sites across Australia as part of Geoscience Australia's Exploring for the Future program. It presents new data and information regarding the tenor and deportment of indium, gallium, germanium, cadmium, antimony, and bismuth, as well as silver, lead, zinc, and copper at the Zeehan tailings site in western Tasmania.

Geoscience Australia’s Exploring for the Future program provides precompetitive information to inform decision-making by government, community and industry on the sustainable development of Australia's mineral, energy and groundwater resources. By gathering, analysing and interpreting new and existing precompetitive geoscience data and knowledge, we are building a national picture of Australia’s geology and resource potential. This leads to a strong economy, resilient society and sustainable environment for the benefit of all Australians. This includes supporting Australia’s transition to net zero emissions, strong, sustainable resources and agriculture sectors, and economic opportunities and social benefits for Australia’s regional and remote communities. The Exploring for the Future program, which commenced in 2016, is an eight year, $225m investment by the Australian Government.
