SA Exploration Initiative 1993 - Area B5 (Moomba) (P768), radiometric line data, AWAGS levelled

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 SA Exploration Initiative 1993 - Area B5 (Moomba) (P768), radiometric line data, AWAGS levelled were acquired in 1993 by the SA Government, and consisted of 8298 line-kilometres of data at a line spacing between 200m and 400m, and 70m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

Automatically Calculating the Adherence to License Requirements

Through the experiences of building several information infrastructures in Australia we have come to wanting to calculate the properties of data licenses in as automated a fashion as possible. To do this, we have trialed decomposing licenses into individual requirements, building on the Creative Commons Rights Expression Language (CC REL) information model (http://creativecommons.org/ns). Such a decomposition, along with the separation of rights management from licenses as per the Open Data Rights Statement vocabulary (ODRS) model (http://schema.theodi.org/odrs/), allows us to model very many different licenses as simple collections of common requirements. In Car & Stenson (2015) we posited requirement resolution actions that systems or people can undertake that satisfy individual requirements and show how systems can b e made to automatically satisfy certain classes of requirements but certainly not all.  

We are not currently able to automate every aspect of license requirement adherence and we believe that full automation is impossible, however every bit of automation improves the efficiency of data delivery. 

In this presentation we report on some aspects of our license model, including the modelling of requirements and their resolutions. We also show how such modelling can enhances data access by comparing the status quo and possible future delivery of data via a large multi -agency, Australian data generation project; the Bioregional Assessments Programme.

GSWA Paterson North elevation grid geodetic

Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This GSWA Paterson North elevation grid geodetic is elevation data for the Paterson North, WA, 2005. This survey was acquired under the project No. 1091 for the geological survey of WA. The grid has a cell size of 0.00083 degrees (approximately 90m).  This grid contains the ground elevation relative to the geoid for the Paterson North, WA, 2005. It represents the vertical distance from a location on the Earth's surface to the geoid. The data are given in units of meters. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.

Geological Timewalk Booklet

This publication was developed as a guide to be used in conjunction with the Geoscience Australia TimeWalk but can also be used as a standalone guide on geological time. Each section in this publication discusses a single geological time interval, and outlines the major geological, climatic and biological events which occurred in that interval. Geological events include continental drift, the break-up and amalgamation of continental landmasses, mountain-building and major volcanic eruptions. Climatic events include changes in the content of the atmosphere and the occurrence of ice ages. Biological events include the evolution of major groups of organisms, the invasion of the land and major extinctions. Other events include changes in sea levels as well as major meteorite impacts. Each section also shows where rocks of a specific age are found in Australia and lists some of the continent's major mineral and energy resources formed during a particular time interval.

Frome, SA, Broken Hill Exploration Initiative, 1995 (P641), magnetic line data, AWAGS levelled

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.
 These line dataset from the Frome, SA, Broken Hill Exploration Initiative, 1995 survey were acquired in 1995 by the SA Government, and consisted of 68300 line-kilometres of data at 400m line spacing and 80m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

Interactions between tectonostratigraphy, depositional environments and sediment dispersal patterns in the Cooper Basin

This seminar will showcase new results from the late Carboniferous to Middle Triassic Cooper Basin that challenge existing notions on its evolution, new insights on sediment dispersal pathways and consequently its resource potential. Topics that will be explored include how the Cooper Basin is similar to other failed rift basins and how depositional facies between each of the half-grabens/troughs are influenced by the relationship between sediment supply and the rate of creation of accommodation. Of note are new precise dates and carbon isotope data from the thick coals of the Patchawarra Formation suggesting prolonged and uninterrupted peat accumulation for millions of years during the latter stages of the late Palaeozoic ice age – no modern analogue exists to compare the conditions and longevity of these ancient mires. Come along to the talk to learn more about the Cooper Basin.

The metallogenic potential of Australian Proterozoic granites

This Geoscience Australia Record 2001/12 is the result of 'The Metallogeny of Australian Proterozoic Granites' project, undertaken by the then Australian Geological Survey Organisation in collaboration with 20 minerals exploration companies. The project was a data driven exercise that asked the simple question:

'Where hydrothermal Au, Cu, Zn, Pb, Sn, W, and Mo mineralisation occurs within 5 kms of the boundaries of Proterozoic Granites, are there any specific characteristics of either the granites and/or their host rocks?'

The project compiled data on the mineralogy, geochemistry (~7500 analyses), and age of Proterozoic granites and felsic volcanics, as well as the age and mineralogical composition of sediments within 5 kms of Proterozoic granite boundaries for 20 provinces. The project investigated a spatial association only, and hence it was not considered of major importance if the metals came from the granite or had been leached from the country rock by processes related to granite emplacement. 
Further, the compilation made every effort to focus on factual data. As the determination of the tectonic setting operating at the time of emplacement of the granites, particularly in rocks as old as Proterozoic, was considered to be highly interpretative, this parameter was not included, due to the data-driven approach of the project.

Having compiled the data, a forensic data mining approach was applied. That is, rather than developing a computer derived 'best-fit model' from the data, or taking an existing model and finding areas that matched the prescribed model, a more descriptive approach was tried. Our goal was to investigate the spatial relationship to gain understanding by uncovering patterns and relationships.

Tallaringa North - dose rate grid (AWAGS)

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. The total dose rate is due to natural sources of radiation and is computed by adding estimates of cosmic dose at ground level to the terrestrial dose. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered total dose rate grid.
This Tallaringa North - dose rate grid (AWAGS) has a cell size of 0.00042 degrees (approximately 44m) and shows the total dose rate of the Tallaringa North Airborne Magnetic Radiometric and DEM Survey, SA, 2017 survey. The data used to produce this grid was acquired in 2017 by the SA Government, and consisted of 98230 line-kilometres of data at 200m line spacing and 60m terrain clearance.

The Beetaloo Sub-basin Baseline Seismic Monitoring Project – Phase 1 Observations

Public concerns have been raised about the potential for induced seismicity as state and territory governments lift moratoriums on hydraulic stimulation activities for the exploration and extraction of unconventional hydrocarbons. The Scientific Inquiry into Hydraulic Fracturing in the Northern Territory articulated the need for a traffic-light system “to minimise the risk of occurrence of seismic events during hydraulic fracturing operations” within the Beetaloo Sub-basin. A temporary seismic network (Phase 1) was deployed in late 2019 to monitor baseline seismic activity in the basin. Based on the data analysed herein (November 2019 – April 2021), no seismic events were identified within the area of interest suggesting that the Beetaloo Sub-basin is largely aseismic. Observations to date indicate that there is potential to identify events smaller than ML=1.5 within the basin. The recent installation of ten semi-permanent stations for continuous real-time monitoring will contribute to ongoing baseline monitoring efforts and support the implementation of an induced seismicity traffic-light system. The outcome of this study will be used to build knowledge about potential human-induced seismic activity in the region that may be associated with unconventional hydrocarbon recovery.
This paper was presented at the Australian Earthquake Engineering Society 2021 Virtual Conference, Nov 25 – 26.
