GSSA Warrina Potassium rate Grid Geodetic

This GSSA Warrina Potassium rate Grid Geodetic is an airborne-derived radiometric potassium window countrate grid for the Warrina Airborne Magnetic Radiometric and DEM Survey, SA, 2017 survey. The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). 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 GSSA Warrina Potassium rate Grid Geodetic radiometric potassium window countrate grid has a cell size of 0.00042 degrees (approximately 44m). The data are in units of counts per second (cps). The data used to produce this grid was acquired in 2017 by the SA Government, and consisted of 135932 line-kilometres of data at 200m line spacing and 60m terrain clearance.

Kingoonya - TMI RTP grid (AWAGS)

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. 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 magnetic grid has a cell size of 0.0004 degrees (approximately 41m).The data are in nanoTesla (or nT). The data used to produce this grid was acquired in 2018 by the SA Government, and consisted of 149477 line-kilometres of data at 200m line spacing and 60m terrain clearance. To constrain long wavelengths in the grid, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey grid. This survey grid is essentially levelled to AWAGS.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.

Gunanya 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.

Pinnaroo Hydrogeological map of the Murray Basin series 1:250 000

The objectives of hydrogeologically mapping the Murray basin were to generate a set of maps at 1:250 000 scale to: 

show the influence of groundwater on land salinisation and surface water salinity 
delineate useable groundwater resources 
highlight present and potential salinity hazard and 
enhance community awareness and understanding of groundwater systems and processes 

and provide a groundwater data-base for the Murray Basin to facilitate land and water resource management decisions. 
The production of the Murray Basin Hydrogeological Map Series was a major coordinated Government action in the management of groundwater to combat degradation through salinisation and enable sustainable land and water use in the Murray Basin.  The Hydrogeological Map Series was a collaborative effort between the various water authorities of South Australia, Victoria and New South Wales. 
Explaining this product in detail is an article by Evans, W.R. 1992, "The Murray Basin Hydrogeological Map Series", Water pp. 20-23.

Australian Mineral Exploration: analysis and implications

Australian mineral exploration is at a 20 year low in real terms. After doubling in line with global exploration activity during the 1990s, exploration expenditure peaked in 1996/97 and then fell sharply. The current decline differs from previous downturns in exploration that have occurred as part of the economic cycle as it is accompanied by major structural changes in the industry. Forces resulting in these changes are strongly inter-related and include:
&#8226; cost cutting to stay competitive in the face of low (declining) commodity prices
&#8226; demand for greater return on shareholder investment
&#8226; consolidation in response to globalisation
&#8226; intense competition for risk capital (particularly for junior companies) from new sources
&#8226; loss of confidence in exploration as an economic activity following declining rates of discovery 
and land access issues.
These factors have changed and continue to change the face of the industry.

Geochemistry of organic rich shales in the Roper and Isa Superbasins of Northern Australia

The Proterozoic was an important eon which saw profound changes in the geochemistry of the oceans and the first appearance and proliferation of complex life [1]. In this study we examine the relationships between organic matter and ocean geochemistry in sedimentary sequences in Northern Australia.  
The geobiology of the McArthur Basin has been comprehensively studied and characterised. The ca. 1.3 Ga Velkerri Formation within the Roper Superbasin is predominantly ferruginous with episodes of euxinia coupled to enhanced primary productivity [2]. In contrast, black carbonaceous shales of the ca. 1.6 Ga Fraynes and Barney Creek Formations are pervasively anoxic and euxinic [3]. The latter formation is dominated by aromatic isoprenoids, biomarkers for green and purple sulfur bacteria commonly associated with photic zone euxinia [4]. In contrast, little attention has been given to the likely coeval South Nicholson Basin and Lawn Hill Platform located directly south of the McArthur Basin, straddling the Queensland and Northern Territory border.  
Here we provide new insights into the paleo-environments of Paleoproterozoic and Mesoproterozoic sedimentary successions in the Lawn Hill Platform and South Nicholson Basin based on multi-proxy sedimentary geochemical analyses including biomarkers, isotopes (?13C, ?15N and ?34S) and trace metals. The results in this study while preliminary at present, demonstrate redox heterogeneity with oscillations between ferruginous and euxinic conditions broadly correlating with increases in total organic carbon content. Complexities in the data remain including potential influences of hydrothermal alteration on the thermal evolution, and mobility and abundances of trace metals in some sections of the basins.
