Petrology and geochemistry of acid igneous rocks of northeast Queensland

Acid igneous rocks of northeast Queensland range in age from Precambrian to Permian.The Precambrian to Devonian Forsayth and Robin Hood Granites and the Siluro-Devonian Dumbano Granite and Dido Granodiorite form deep-level intrusions and have generally unfractionated compositions, with relatively high K/Rb and low K/Na ratios. The only significant mineralization associated with them is gold. The Proterozoic Esmeralda Granite and Croydon Volcanics and the extensively mineralized Upper Palaeozoic high-level granitic rocks and their associated volcanics are mostly highly fractionated, with high K2O, Rb, Y, Th, U, and in some cases Li and Be contents, and low K/Rb ratios. The Esmeralda Granite and Croydon Volcanics are considered to have been derived by anatexis of K-rich sialic crustal rocks, but isotopic and chemical data suggest that the Upper Palaeozoic acid magmas originated by anatexis of Rb-poor deep crustal material, possibly caused by rising basaltic or andesitic magmas derived by melting of subducted oceanic crust. Granitic rocks with associated tin mineralization, including the Esmeralda Granite and several of the more fractionated Upper Palaeozoic granitic rocks are enriched in volatile elements such as Li, Be, B and F. Sn contents are significantly higher than those of non-stanniferous granites, but lower than values reported for many Sn-granites elsewhere. No correlation of granite geochemistry with Pb/Zn or Cu mineralization was found.

The hydrogeology of the Murray Basin, southeastern Australia

Soil degradation is the most serious environmental issue facing Australia today, and a major problem is the land salinisation and degradation of surface water quality in the Murray Basin of southeastern Australia. Most of the salinity problems are ground-water related, and it is only by understanding regional groundwater processes that effective management plans can be formulated to combat the spread of salinity throughout the basin.  Regional aquifers of the Murray Basin can be put into three distinct provinces. The Riverine province underlies the Riverine Plain and the eastern Mallee region in New South Wales and Victoria, the Mallee-Limestone province underlies the Mallee south of the Murray River in South Australia and the Wimmera and western Mallee in Victoria, and the Scotia province occupies the most arid part of the basin east and south of the Barrier Range in South Australia and New South Wales. Groundwater flow in the three provinces is towards the Murray River, which is the sole conduit for the transport of groundwater and salts out of the basin.  The major aquifers of the Murray Basin are the Renmark Group, Murray Group, Pliocene Sands and Shepparton Formation. The major impediment to flow , the mid-Tertiary low-permeability barrier, extends in an arc about 100 km wide through the centre of the basin. The barrier (a composite of the Winnambool Formation/Geera Clay) disrupts lateral throughflow in the Renmark Group aquifers and overlying Pliocene Sands. This disruption is one of the factors that controls the distribution of groundwater discharge zones, the extent of which is ultimately controlled by groundwater pressure in recharge zones. The Geera Clay is also a source of salts which diffuse downward into the lower Renmark Group aquifer. Land clearing since European settlement in the recharge zones has increased the rainfall infiltration capacity of soils, thereby increasing water pressure. This has resulted in rising water tables down-basin and reactivation of many ancient discharge zones, particularly in Victoria. However, land salinisation has been much more widespread in the recent geologic past. The Murray Basin aquifers contain about 4600 million megalitres (ML) of groundwater in storage, two-thirds of which is useful to humans.  The total salt load in the aquifers and aquitards exceeds 100000 million tonnes and, under the current groundwater- surface water interactive flow regime, &lt; 0.004% of this huge salt store is transported out of the basin annually by the Murray River. Recoverable reserves of groundwater in the unconfined aquifers total around 4.5 million ML/ year. The utilisation rate is only a few per cent of the sustainable yield in the unconfined aquifers and even less in the confined aquifers. Greater use of groundwater in recharge zones would ultimately reduce the rate of rise of the regional down-basin water table, though salt disposal considerations are the limiting factor on any development.

Collection of porosity and permeability data from petroleum wells (known as RESFACS database/ Porosity and Permeability)

Porosity and permeability data form part of Geoscience Australia’s Reservoir, Facies and Shows (RESFACS) database, which contains depth-based information regarding porosity and permeability measured or interpreted from core, sidewall core and well-log analysis of rocks intersected by offshore petroleum wells. Porosity and permeability are rock properties related to the number, size, and connectivity of openings in the rock. More specifically, porosity of a rock is a measure of its ability to hold a fluid within pore-spaces and the permeability is a measure of the ease of flow of a fluid through a porous solid.
Data entered into the porosity and permeability tables are primarily sourced from the Basic and Interpretive volumes of Well Completion Reports (WCR) provided by the petroleum industry to the Commonwealth under the Offshore Petroleum and Greenhouse Gas Storage Act (OPGGSA) 2006 and the previous Petroleum (submerged Lands) Act (PSLA) 1967. Data is also sourced from sedimentologic evaluations and petrophysical studies by Geoscience Australia and its predecessor organisations, the Australian Geological Survey Organisation (AGSO) and the Bureau of Mineral Resources (BMR), as well as from state and territory geological organisations, and scientific publications.
The database structure has evolved over time and will keep changing as different types of relevant data become available and the delivery platform changes. Data hosted within Geoscience Australia’s Oracle petroleum wells database was initially delivered through the Petroleum Wells web page, http://dbforms.ga.gov.au/www/npm.well.search, which is in the process of being decommissioned . The porosity and permeability data will now be available to view and download through the Geoscience Australia Portal Core, https://portal.ga.gov.au/. Use Porosity and Permeability as your search term to find the relevant data.

Cobar magnetic and radiometric survey, NSW, 2021 (P5009), Extension 6, magnetic line data

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.

AusLAMP shines a light on space weather hazards in the Australian high-voltage power grid

A geomagnetic storm, also known as a geomagnetic disturbance (GMD), is a major disturbance of the Earth’s magnetic field caused by solar activity. A geomagnetic storm induces electric currents in the Earth that feed into power lines through substation neutral earthing, causing instabilities and even blackouts in electricity transmission systems. The intensity of geomagnetically induced currents (GICs) is closely associated with the electrical conductivity of the surrounding geology. In this paper, we analyse one of the most well-known geomagnetic storms, the 1989 “Québec storm” and 688 magnetotelluric (MT) survey sites from the Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) to gain insight into the space weather hazard posed for Australia's modern-day power grids. Transmission lines may exhibit local maxima at differing times depending on their spatial orientation and length with respect to the time-varying magnetic field. Localised peak voltages over 100 V can be observed on some individual lines. This assessment identifies the distribution of GICs in south-eastern Australia for the 1989 Québec storm and transmission lines that are more vulnerable to GICs. It is relevant to national strategies and risk assessment procedures to mitigate space weather hazards in the Australian high-voltage power grid and the design of a more resilient power transmission system. We also analyse the 2015 “St Patrick’s Day storm” to study under-estimation of the space weather hazard associated with the band-limited geomagnetic data and MT data sets.

Digital Earth Australia - Open Cloud Infrastructure

Digital Earth Australia manages a cloud based service that makes use of open source software and open standards to deliver satellite imagery to its clients.

In conjunction with Frontier SI and Commonwealth Scientific and Industrial Research Organisation, Geoscience Australia’s Digital Earth Australia project has developed a cloud architecture that utilizes the Open Data Cube (ODC) to deliver Earth Observation (EO) data through Open Geospatial Consortium (OGC) API standards, interactive Jupyter notebooks and direct file access.​

This infrastructure enables EO data to be used to make decisions by industry and government partners, and reduces the time required to deliver new EO data products. ​

To store the data, DEA utilises Amazon Web Services (AWS) Object store: Simple Storage Service (S3) to hold an archive of Cloud Optimised GeoTIFFs (COGs). ​

This data is indexed by Open Data Cube (ODC) an open source python library. DEA deploy processing, visualisation and analysis applications that make use of the indexed data. This method reduces the duplication of code and effort and creates an extensible framework for delivering data.
