Gravity Survey SA 96I1 (P199653), 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 Gravity Survey SA 96I1 (P199653) contains a total of 40 point data values acquired at a spacing of 5000 metres. The data is located in SA and were acquired in 1996, under project No. 199653 for None.

Geochemistry of the North Australian Craton: Piecing it Together

Australia has a significant number of surface sediment geochemical surveys that have been undertaken by industry and government during the past 50 years. These surveys represent a vast investment, but up to now have been  used in isolation from one another. The key to maximising the full potential of these data and the information they provide for mineral exploration, environmental management and agricultural purposes is using all surveys together, seamlessly. These geochemical surveys have not only sampled various landscape elements but have used multiple analytical techniques, instrumentation and laboratories. The geochemical data from these surveys need to be levelled to eliminate, as much as possible, non-geological variation. Using a variety of methodologies, including reanalysis of both international standards and small subsets of samples from previous surveys, we have created a seamless surface geochemical map for northern Australia, from nine surveys with 15605 samples. We tested our approach using two surveys from the southern Thomson Orogen, which removed interlaboratory and other analytical variation. Creation of the new combined and levelled northern Australian dataset paves the way for the application of statistical techniques, such as principal component analysis and machine learning, which maximise the value of these legacy data holdings. The methodology documented here can be applied to additional geochemical datasets
that become available.

The geology and mineral deposits of the Proterozoic in Western Australia

The evolution of the geology and mineral deposits of the Proterozoic in Western Australia can be described in terms of episodes of continental breakup, terrane accretion and plate aggregation. The Hamersley Basin represents breakup of an Archaean continent in the late Archaean to earliest Palaeoproterozoic (2800-2300 Ma). A period of plate aggregation occurred in the Palaeoproterozoic between 1900 and 1750 Ma with the formation of the North, South, and West Australian Cratons, probably as parts of larger continents. A period of intracratonic basin formation followed in the earliest Mesoproterozoic, around 1600 Ma.  A second period of terrane accretion and plate aggregation took place in the late Mesoproterozoic between 1300 and 1000 Ma, during which the main crustal components of Proterozoic Australia were assembled as part of the Rodinian supercontinent. Proterozoic Australia remained essentially intact during Neoproterozoic continental breakup at ~750 Ma. Old Palaeoproterozoic and Mesoproterozoic sutures were reactivated as intracratonic orogenic belts between 560 and 540 Ma, during the late Neoproterozoic assembly of a new supercontinent. Two broad groups of mineral deposits, related to different tectonic regimes, can be recognised: volcanogenic massive sulphide deposits, stratiform sediment-hosted deposits, and hydrothermal vein systems related to rifting and basin formation; and mesothermal lode mineralisation, formed from magmatic, deformational, and metamorphic events linked to compressional tectonics. Although there are similarities, the geological evolution and mineralisation of individual orogenic belts and basins do not conform simply to models developed in the Proterozoic of northern and northeastern Australia. Given the low level of exploration activity and poor exposure in many areas, and recognising that mineralisation related to large-scale hydrothermal systems has occurred at various times throughout the Proterozoic, the potential exists for the further discovery of large-scale mineralisation.

Malcolm 1:250 000, R502 historical topographic map

The R502 series of maps has been replaced by the National Topographic Map Series (NTMS). The R502 series consists of 542 map sheets and covers Australia at a scale of 1:250,000. It was compiled from aerial photography, but only about one quarter of the series was contoured. The standard sheet size is 1 degree of latitude by 1.5 degrees of longitude. Transverse Mercator map projection and Clark 1858 datum were used. Coverage of the country was completed in 1968.

Notes on search for airborne scintillometer anomaly, Katherine area

The air-borne scintillometer survey near Katherine during October, 1953, failed to cover a triangular area in the south-east corner of the Katherine sheet, as it was beyond the range of the Shoran beacons. The area is part of a Bureau of Mineral Resources reservation taken out to protect the ABC Prospect. Several trial flights were made over the area, however, in an attempt to detect the presence of any significant radiometric anomalies. During these flights, Geologist A.B. Clark acted as an observer to spot on photo-mosaics the positions at which anomalies might occur. A third order anomaly was recorded during a flight along Maude Creek at a point thought to be within 1 mile of the junction of Dorothy Creek and Maude Creek. A search was made later by D.E. Gardner with the object of finding the source of the anomaly and the results of this work are given below.

Ord Valley AEM Interpretation Project - ATLAS Ord River Irrigation Area Phase 1

In 2008, the Ord Irrigation Cooperative commissioned an airborne electromagnetics (AEM) survey of the ORIA Stage 1 and 2 areas to identify, quantify and understand any potential salinity risks in the current Ord irrigation area and the parts of the catchment that have been identified as potential future irrigation sites or potentially impacted by future irrigation. The project has been funded by the Australian and Western Australian governments through the National Action Plan for Salinity and Water Quality. Geoscience Australia and CSIRO were contracted to carry out the analysis and interpretation of the AEM dataset, and produce customised interpretation products.
Some of the more specific questions it was hoped to address included:
- Are we at risk of salinity in the Ord Catchment?
- If so what areas are at the greatest risk?
- Where can we target management to reduce this risk?
- How can we plan future development to minimise salinity risk and maximise longevity of projects?
The areas surveyed include the current Stage 1 Ord Irrigation Area, Stage 2 Irrigation Area (including Weaber and Knox Plains and Carlton Hill - Parry's Lagoon Conservation Area.  The inclusion of undeveloped land in this survey is because the technology provides the opportunity to ensure any future irrigation development is guided by the best available information on soil type, aquifer quality and location and salinity risk. 
The information generated by this project will be publicly available and can be used for such things as: 
- Identifying leaky areas in the landscape that may require more concentrated management or can be designated for more suitable land use;
- Where salt is stored in the landscape and at what depth, and where in the landscape it may influence plant growth;
- Provide new constraints on the connectivity of aquifer systems in 3D across the ORIA and enable the construction of more realistic hydrogeological models to improve surface and groundwater management.

Flinders Ranges percent potassium grid geodetic

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 radiometric potassium grid has a cell size of 0.00042 degrees (approximately 43m) and shows potassium element concentration of the Flinders Ranges, SA, 1998 in units of percent (or %). The data used to produce this grid was acquired in 1999 by the SA Government, and consisted of 127752 line-kilometres of data at a line spacing between 200m and 400m, and 60m terrain clearance.

Source rock type, maturation levels and hydrocarbon potential of a suite of samples from NDI Carrara 1 well, Northern Territory

This study was commissioned by Geoscience Australia (GA) to produce a report on source rock maturity and maceral/organoclast assemblages for a suite of rock samples from from the MinEx CRC National Drilling Initiative (NDI) Carrara 1 drill hole in the Northern Territory, Australia. 25 samples consisting of 24 drill core samples and 1 drill cutting sample were studied using organic petrological methods to evaluate the organic matter type, content, thermal maturity and hydrocarbon potential. Vitrinite was absent in all the samples and variable amounts of bitumen was present throughout the stratigraphic section studied.  Fluorescing lamalginite was present in the upper part of the section and no bioclasts were detected in the samples from the lower section.  Vitrinite reflectance equivalents calculated from bitumen reflectance indicated that upper part of the section containing lamalginite is early to mid-mature and the lower part of the section is over-mature.  Good potential for liquid hydrocarbons may exist in the upper part of the section and the overmature lower part of the stratigraphic section could be gas prone.
