GSWA South Yilgarn ppm uranium 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 uranium grid has a cell size of 0.00083 degrees (approximately 85m) and shows uranium element concentration of the South Yilgarn merge, 1987-2005 in units of parts per million (or ppm). The data used to produce this grid was acquired in 1987 by the WA Government, and consisted of 392575 line-kilometres of data at a line spacing between 100m and 400m, and 60m terrain clearance.

Galilee Basin regional geology package

Publicly available geology data are compiled to provide a common information base for resource development and regulatory decisions in the Galilee Basin region. This data guide gives examples of how the compiled data can be used. It supports a data package that presents core photographs, existing knowledge of the stratigraphy, and structural elements for the Galilee Basin and the overlying Eromanga, Lake Eyre and other Cenozoic basins.
Stratigraphic frameworks capture the geological groups and formations that make up the sedimentary sequence in the Galilee Basin region. The Galilee Basin includes 4 stratigraphic groups. From deepest to shallowest, these are the Joe Joe Group, Betts Creek group, Rewan Group and Clematis Group. Overlying the Galilee Basin are the geological formations of the Eromanga, Lake Eyre and other Cenozoic basins.
The frameworks include the stratigraphic intervals used by the Trusted Environmental and Geological Information (TEGI) Program. From the base of the Galilee Basin to the top of overlying Cenozoic basins, the sedimentary sequence is categorised into 15 play intervals for resource assessment mapping and 11 hydrostratigraphic intervals for characterising groundwater systems (Wainman et al., 2023).
Structural elements maps summarise where the sedimentary sequence has been deposited and later deformed by crustal movements. Structure information is used in assessing the geological potential for resources and interpreting groundwater flow and connectivity at the basin scale. The stratigraphic frameworks and structural elements provide the basic geological context for the Galilee Basin region geological, resource and environmental assessments.

Summary of results for the joint GSNSW - GA geochronology project: New England Orogen and Sydney-Gunnedah Basin April-July 2008

This report presents new SHRIMP U-Pb zircon results for 9 samples from the New England region and one from the Dubbo region. It was carried out under the auspices of the National Geoscience Agreement (NGA) between Geoscience Australia and the Geological Survey of New South Wales. The data and age interpretations contained in this report are available in the OZCHRON database, maintained by Geoscience Australia (http://www.ga.gov.au/oracle/ozchron/index.jsp). 
The age results in this report for the Gilgai Granite (Sn, Ag) and Parlour Mountain Leucomonzogranite (Mo) establish that some mineralised intrusions are temporally (and probably genetically) related to the main phase of I-type magmatism in New England represented by the Uralla and Moonbi Supersuites. This suggests that the eruptive equivalents of highly evolved and mineralised magmas may be present within the Wandsworth Volcanic Group. These units would have potential for epithermal style deposits, and rhyolite hosted Sn and U mineralisation.

Magnetic petrophysics and magnetic petrology: aids to geological interpretation of magnetic surveys

The present capability to acquire, process and display very large sets of high-quality magnetic survey data has far outstripped the capacity to extract all the geological information from the data.  Interpretation of magnetics has lagged behind, largely because of a lack of information on magnetic properties within the survey areas and because the geological factors and processes that determine magnetic signatures are often poorly understood.  In the absence of magnetic property measurements, simplistic rules-of-thumb concerning magnetic properties of different rock types can be deceptive.  Furthermore, empirical correlations between mapped geology and magnetics in one area cannot necessarily be extrapolated to other areas of poor exposure if changes in depositional environment, metamorphic grade or structural setting are ignored.  Magnetic modelling is afflicted by the inherent non-uniqueness of source geometry.  Information on magnetic properties in the area of interest is important for constraining interpretation in order to resolve this ambiguity.  Magnetic petrology integrates rock magnetism and conventional petrology in order to define the processes that create, alter and destroy magnetic minerals in rocks.  By relating magnetic mineralogy, bulk magnetic properties, petrology and geochemistry to observed magnetic anomalies an understanding of the geological factors that control magnetic signatures is obtained, which can be used to improve geological interpretation of magnetic surveys.

Precise Point Positioning with Ginan, Geoscience Australias Open Source GNSS Analysis Centre Software

Ginan is a GNSS (Global Navigation Satellite System) analysis centre software that is currently being developed by Geoscience Australia in partnership with industry and academic partners. Ginan is fully open-source software based on the SSR (State Space Representation), PPP (Precise Point Positioning) model and is capable of computing precise positioning products, delivering real-time correction services, as well as operating as a user-driven precise positioning engine.

Ginan is a modern, multi-threaded C++ application that utilises industry standard high-performance libraries such as Eigen3, and Boost. Software configuration is managed through industry standard YAML (YAML Ain’t Markup Language) files. Standard IGS (International GNSS Service) file-based products are produced, and intermediate positioning products are managed in the open-source NoSQL MongoDB database and output is through standard Radio Technical Commission for Maritime Services-3 (RTCM3), IGS-SSR and Compact SSR message streams. At its core, Ginan is a customised and optimised Kalman filter that is tightly coupled with a data pre-processor and orbit integrator, enabling both real-time processing of industry standard RTCM3 data messages streams and post-processing using IGS positioning products.

The purpose of Ginan is to provide users with a unique multi-GNSS real-time processing platform capable of delivering precise positioning products to the Australian and international Positioning Navigation and Timing (PNT) community; support expert advice on navigation system performance over Australia; and provide state-of-the-art GNSS analysis centre software to universities and research organisations to enable Australia to lead in the development of geospatial technology. Ginan can be used for many geodetic and positioning activities such as computation of daily coordinate solutions, precise satellite orbit determination, computation of satellite clocks & biases, atmospheric modelling, data QA/QC and more. This paper describes the Kalman filter optimization methodology implemented in Ginan and provides benchmarking comparisons of Ginan against the International GNSS Service combined orbit and clock products.

Selection of Ground-Motion Models for National Seismic Hazard Assessment of Australia

One of the key challenges in assessing earthquake hazard in Australia is understanding the attenuation of ground-motion through the stable continental crust. There are now a small number of ground-motion models (GMMs) that have been developed specifically to estimate ground-motions from Australian earthquakes. These GMMs, in addition to models developed outside Australia, are considered here for use in the updated national seismic hazard assessment of Australia. An updated and extended suite of ground-motion data from small-to-moderate Australian earthquakes are used to assess the suitability of the candidate models for use in the Australian context. Recorded spectral intensities are compared with those predicted by the GMMs. Both qualitative and quantitative approaches are considered for such comparisons. The goodness-of-fit results vary significantly among different GMMs, spectral periods and distance ranges; however, overall, the Australian-specific GMMs seem to perform reasonably well in estimating the level of ground shaking for earthquakes in Australia.

This paper was presented to the 2022 Australian Earthquake Engineering Society (AEES) Conference 24-25 November (https://aees.org.au/aees-conference-2022/)

HiQGA: High Quality Geophysical Analysis

From being a poorly understood qualitative mapping tool, airborne electromagnetic (AEM) geophysics has become a mainstay for rapidly imaging the top few hundred metres of buried earth for a variety of geoscientific and environmental purposes. In this talk, we will detail GA’s quest to provide high quality, quantitative interpretation of AEM sounding data. Beginning with a 20-year historical perspective, we will shed light on how persistent focus on AEM technology directly led to AusAEM, the world’s largest (ongoing) AEM survey. We will then discuss how continuing focus on AEM has led to the development of an open source framework written in the Julia language, for subsurface imaging AND uncertainty quantification. This codebase is useful for geophysical methods beyond AEM, such as magnetotellurics and magnetic resonance. Finally, we will dwell on some real life examples using the new codebase and will look to the future of AEM@GA and its untapped potential.

Geomorphology Smartline Geopackage

The term "Smartline" refers to a GIS line map format which can allow rapid capture of diverse coastal data into a single consistently classified map, which in turn can be readily analysed for many purposes. This format has been used to create a detailed nationally-consistent coastal geomorphic map of Australia, which is currently being used for the National Coastal Vulnerability Assessment (NCVA) as part of the underpinning information for understanding the vulnerability to sea level rise and other climate change influenced hazards such as storm surge. The utility of the Smartline format results from application of a number of key principles. A hierarchical form- and fabric-based (rather than morpho-dynamic) geomorphic classification is used to classify coastal landforms in shore-parallel tidal zones relating to but not necessarily co-incident with the GIS line itself. Together with the use of broad but geomorphically-meaningful classes, this allows Smartline to readily import coastal data from a diversity of differently-classified prior sources into one consistent map. The resulting map can be as spatially detailed as the available data sources allow, and can be used in at least two key ways: Firstly, Smartline can work as a source of consistently classified information which has been distilled out of a diversity of data sources and presented in a simple format from which required information can be rapidly extracted using queries. Given the practical difficulty many coastal planners and managers face in accessing and using the vast amount of primary coastal data now available in Australia, Smartline can provide the means to assimilate and synthesise all this data into more usable forms.

Summary Of Data And Results Gippsland Basin, Victoria Wellington Park No 1 Well Of Woodside (Lakes Entrance) Oil Company NL

Wellington Park No. 1 Well was located in the Gippsland Basin, Victoria, on the south-eastern shore of Lake Wellington. about 25 1/2 miles south-west of Bairnsdale. The well was drilled by Oil Drilling and Exploration Limited for Woodside (Lakes Entrance) Oil Company No Liability. to a total depth of 12,011 feet. Drilling commenced on 6th December. 1961 and was completed on 3rd April. 1962. A comprehensive programme of drilling engineering, mud logging, coring. cuttings examination. and electric logging was conducted, but no significant shows of oil or gas were encountered.
The well penetrated Quaternary sediments from surface to 120 feet. Tertiary sediments from 120 to 3370 feet. and Mesozoic non-marine sediments from 3370 feet. and bottomed in the Lower Cretaceous - (?)Jurassic Strzelecki Group at 12,011 feet. Palaeozoic rocks. one of the main objectives. were not reached because of the extreme thickness of the Mesozoic section.
Five open hole formation tests over various intervals between 7348 and 9930 feet were undertaken, but only three were successful. These tests produced mud filtrate, mud, and formation water. The well was plugged and abandoned as a dry hole on 7th April, 1962.
The stratigraphic drilling operation at Wellington Park No. 1 was subsidized under the Petroleum Search Subsidy Act 1959. from 3391 feet to total depth.
