Interpretations from the Frome airborne electromagnetic survey

The Frome airborne electromagnetic (AEM) survey is the last and largest (in line kilometres and area) of the three AEM surveys flown under the Onshore Energy Security Program at Geoscience Australia. The survey covered about 95 000 km2 (about six 1:250 000 map sheets) and covered the Frome Embayment, northern Murray Basin and the flanks of the Eromanga Basin in South Australia. Survey data are providing new insights into the stratigraphy of the Frome Embayment and Murray Basin, and will add to our knowledge of the sources and sinks of sandstone related uranium mineral systems, as well as base metals, gold and copper, in this highly prospective area, as well as ground water resources. This seminar will present highlights of the survey and demonstrate AEM data integrated with other data sets to develop 3D models to explorable depths, lowering exploration risk.

Australian Hydrochemistry Data

Geoscience Australia and its predecessors have analysed hydrochemistry of water sampled from boreholes (both pore water and groundwater), surface features, and rainwater. Sampling was undertaken during drilling or monitoring projects, and this dataset represents a significant subset of stored analyses.
Water chemistry including isotopic data is essential to better understand groundwater origins, ages and dynamics, processes such as recharge and inter-aquifer connectivity and for informing conceptual and numerical groundwater models. This GA dataset underpins a nationally consistent data delivery tool and web-based mapping to visualise, analyse and download groundwater chemistry and environmental isotope data.
This dataset is a spatially-enabled groundwater hydrochemistry database based on hydrochemistry data from projects completed in Geoscience Australia. The database includes information on physical-chemical parameters (EC, pH, redox potential, dissolved oxygen), major and minor ions, trace elements, nutrients, pesticides, isotopes and organic chemicals. Basic calculations for piper plots colours are derived from Peeters, 2013 - A Background Color Scheme for Piper Plots to Spatially Visualize Hydrochemical Patterns - Groundwater, Volume 52(1) https://doi.org/10.1111/gwat.12118.
Upon loading the data to the database, all hydrochemistry data are assessed for reliability using Quality Assurance/Quality Control procedures and all datasets were standardised. 
This data is made accessible with open geospatial consortium (OGC) web services and is discoverable via the Geoscience Australia Portal (https://portal.ga.gov.au/). This dataset is published with the permission of the CEO, Geoscience Australia.

Multi-scale Topographic Position Image of Australia

A Multi-scale topographic position image of Australia has been generated by combining a topographic position index and topographic ruggedness. Topographic Position Index (TPI) measures the topographic slope position of landforms. Ruggedness informs on the roughness of the surface and is calculated as the standard deviation of elevations.  Both these terrain attributes are therefore scale dependent and will vary according to the size of the analysis window. Based on an algorithm developed by Lindsay et al. (2015) we have generated multi-scale topographic position model over the Australian continent using 3 second resolution (~90m) DEM derived from the Shuttle Radar Topography Mission (SRTM).  The algorithm calculates topographic position scaled by the corresponding ruggedness across three spatial scales (window sizes) of 0.2-8.1 Km; 8.2-65.2 Km and 65.6-147.6 Km. The derived ternary image captures variations in topographic position across these spatial scales (blue local,  green intermediate and red regional) and gives a rich representation of nested landform features that have broad application in understanding geomorphological and hydrological processes and in mapping regolith and soils over the Australian continent.

GSWA Eucla Basin 2 Loongana Thorium 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 thorium grid has a cell size of 0.00042 degrees (approximately 43m) and shows thorium element concentration of the Loongana, WA, 2010 (Eucla Basin 2) in units of parts per million (or ppm). The data used to produce this grid was acquired in 2010 by the WA Government, and consisted of 114979 line-kilometres of data at 200m line spacing and 50m terrain clearance.

Cymbric Vale fauna of New South Wales and early Cambrian biostratigraphy

Preliminary information regarding the occurrence of an Early Cambrian fauna in New South Wales has been published earlier (Opik, 1968); the full report was, however, delayed until the map of the Broken Hill area compiled by G. Rose (1st edn, 1970) provided published geological data. The systematics of the suborder Eodiscina (also represented in the Cymbric Vale Fauna) are revised, completing the revision of the trilobite order Miomera, the first part of which was published earlier (Opik, 1967). The biostratigraphy of the Lower Cambrian is reviewed so as to place the Cymbric Vale fauna within the scale of that Epoch. The described fossils and the rest of the collection are kept in the Bureau of Mineral Resources, Geology and Geophysics, Canberra.

Agreements Ontology

This Agreements ontology is designed to model 'agreements' which are social contracts that include: licenses, laws, contracts, Memoranda of Understanding, standards and definitional metadata. Its purpose is to support data sharing by making explicit the relationships between agreements and data and agreements and Agents (people and organisations). Eventually it will also help with the interplay between different classes of agreements.
We think of this ontology as a 'middle' ontology, that is one which specializes well-known, abstract, upper ontologies and is able to be used fairly widely but is expected to be used particular contexts in conjunction with detailed, domain-specific, lower ontologies. We have tried to rely on: existing agent, data manipulation, metadata and licence ontologies where possible. As such we specialise the ORG and FOAF ontologies; the PROV ontology; the Dublin Core Terms RDF schema &amp; DCAT ontology; and the ODRS vocabulary &amp; Creative Commons RDF data models for those areas, respectively

Collie, WA, 2011 (P1244), 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 South West (Cape Leeuwin - Collie), WA, 2011 survey were acquired in 2011 by the WA Government, and consisted of 101882 line-kilometres of data at a line spacing between 200m and 200m, and 50m 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.

Geophysical survey of the Renison Bell Tinfield, Tasmania

In response to an application by Renison Associated Tin Mines N.L., supported by the Department of Mines, Tasmania, a geophysical survey of the Renison Bell Tin Field was started by the Bureau of Mineral Resources, Geology and Geophysics in 1950 and continued during 1951 and 1952. The field is situated in the West Coast region of Tasmania, and, up to 1955, had yielded concentrates containing about 3,000 tons of metallic tin. The object of the survey was to assist in the finding of additional ore-bodies in the field. In a survey of portion of the field by the, Imperial Geophysical Experimental Survey in 1929-30, the magnetic and self-potential methods were the most successful of those tested, and these methods were therefore used by the Bureau. The work done in 1950 was mainly over known ore-bodies, and the results obtained confirmed the applicability of the methods, as well as proving anomalies that could indicate sulphide bodies containing pyrrhotite. In 1951 and 1952, the survey was extended to the south and east of the area surveyed in 1950. Numerous intense, well-defined anomalies were obtained by each method, and in many places the anomalies obtained by each method agreed generally in position. These anomalies provide strong indications of sulphide mineralization containing pyrrhotite, but testing will be necessary to determine the extent and nature of the mineralization and the tin content thereof. Recommendations are made for the testing of the indications by drill holes and trenches, and for the extension of the survey to other parts of the field, but not until the results of this testing of anomalies are available.

Murray Basin Hydrogeological Project : progress report 5 for half year ending 31 March 1981

The groundwater modelling sub-committee set up by the Steering Committee in June 1980, met in October and recommended that a preliminary model of the Basin should be attempted; it should contain 3 layers, with a 10 x 10 grid (300 nodes) and have the aim of increasing theaccuracy of solutions at later stages by decreasing the grid size.
The sub-committee proposed that a whole basin model be attempted by the South Australian Department of Mines &amp; Energy using a finite element method, and by the Water Resources Commission of New South Wales using a finite difference approach; the methods could then be compared before a more elaborate model was tried.
