Breathing new life into old collections – Using citizen science to revitalise Geoscience Australia Microscope Slide Based collections (Poster for eResearch 2017)

Since soon after the federation of Australia in 1901 Geoscience Australia, and its predecessors organisations, have gathered a significant collection of microscope slide based items (including: thin sections of rock and micro fossils) from across Australia, Antarctica, Papua New Guinea, the Asia Pacific region and beyond. The samples from which the microscope slides were produced have been gathered via extensive geological mapping programs, work conducted for major Commonwealth building initiatives such as the Snowy Mountain Scheme and science expeditions. The cost of recreating this collection, if at all possible, would be measured in the $100Ms (AUS) even assuming that it was still possible to source the relevant samples.
While access to these microscope slides is open to industry, educational institutions and the public it has not been easy to locate specific slides due to the management system. The management of this collection was based largely on an aged card catalogue and ledger system. The fragmented nature of the management system with the increasing potential for the deterioration of physical media and the loss of access to even some of the original contributors meant that rescue work was (and still is) needed urgently.
Achieving progress on making the microscope slides discoverable and accessible in the current fiscally constrained environment dictated a departure from what might be considered a traditional approach to the project and saw the extensive use of a citizen science approach through the use of DigiVol and reference to a small number of onsite volunteers.
Through the use of a citizen science approach the proof of concept project has seen the transcription of some 35,000 sample metadata and data records (2.5 times our current electronic holdings) from a variety of hardcopy sources by a diverse group of volunteers. The availability of this data has allowed for the electronic discovery of both the microscope slides and their parent samples, and will hopefully lead to a greater utilisation of this valuable resource and enable new geoscientific insights from old resources.
One of the other benefits of the use of Digivol has been increasing Geoscience Australia positive exposure to a totally new section of the general public.  It has highlighted the role of the agency to an audience that had previously had little or no involvement with the geosciences.

GSWA Byro 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 Byro elevation grid geodetic is elevation data for the Byro, WA, 2008. This survey was acquired under the project No. 1178 for the geological survey of WA. The grid has a cell size of 0.00083 degrees (approximately 88m).  This grid contains the ground elevation relative to the geoid for the Byro, WA, 2008. 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.

Lithospheric resistivity structures and mineral prospectivity from AusLAMP data in northern Australia

Magnetotelluric (MT) data allow geoscientists to investigate the link between mineralisation and lithospheric-scale features and processes. In particular, the highly conductive structures imaged by MT data appear to map the pathways of large-scale palaeo-fluid migration, which is an important element of several mineral systems. New data were collected as part of the Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) under Geoscience Australia Exploring for the Future (EFTF) program in northern Australian. We use this dataset to demonstrate that the MT method is a valuable tool for mapping lithospheric-scale features and for selecting prospective areas for mineral exploration.
Our results image a number of major conductive  structures at depths up to ~200 km or deeper in the survey region, for example, the Carpentaria Conductivity Anomaly in east of Mount Isa; and the Tanami Conductive Anomaly along the Willowra Suture Zone. These significant anomalies are lithospheric- scale highly conductive structures, and show spatial correlations with major suture zones and known mineral deposits. 
These results provide important first-order information for lithospheric architecture and possible large footprint of mineral systems. Large-scale crustal/mantle conductivity anomalies mapping fluid pathways associated with major sutures/faults may have implications for mineral potential. These results provide evidence that some mineralisation occurs at the gradient of or over highly conductive structures at lower crustal and lithospheric mantle depths. These observations provide a powerful means of highlighting greenfields for mineral exploration in under-explored and covered regions.

The Southern Thomson Orogen VTEMplusÂ® AEM Survey: Using airborne electromagnetics as an UNCOVER application

The Southern Thomson Orogen VTEMplusÂ® AEM survey was undertaken as part of Geoscience Australia's contribution to the Australian Academy of Science's UNCOVER initiative, which has been adopted as part of the Australia Government's National Mineral Exploration Strategy. The aim of the survey was to demonstrate the application of AEM as an exploration tool under cover by generating new data and information regarding depth to basement and cover character. This information is provided to mineral explorers to assist reducing exploration risk by better targeting of drilling in the greenfields southern Thomson Orogen region. 
This report provides a background to the survey, including reviews of the basement and cover geology and mineral systems potential of the southern Thomson Orogen. We present the specifications of the airborne survey, and detail the innovative processing and inversion techniques that have been developed and applied to the AEM data. These inversion innovations have enabled the generation of higher precision information from the AEM data, resulting in higher confidence in geological and geophysical interpretations of the basement-cover interface and overlying basin stratigraphy.
Data interpretation methods are presented, followed by a series of case studies demonstrating the effectiveness of the technique for identifying and mapping resistive basement, for characterising cover sequences, for mapping weathering products and for mapping post-depositional structures. The process and results of basement-cover interface mapping are presented along with conductivity characterisation and recognition of key stratigraphic (and hydrostratigraphic) units within the Eromanga and Lake Eyre basin cover sequences. Interpretation of a potential mineral system in resistive basement is discussed, and the utility of the technique for assessing the distribution and depth of weathering in basement rocks, along with interpretation of tectonic features, are also assessed.
The application of AEM as a basement and cover mapping tool are clearly demonstrated and the potential utility of such techniques for reducing exploration risk in greenfields regions is clear. In the southern Thomson Orogen interpreted AEM data has the potential to assist in targeting exploration and drilling for shallowly-buried basement-hosted mineral systems to 150-200 m and in exploring for distal footprints within the overlying basin cover sequences.

Onshore Energy Security Program: AEM Survey Boundary and Flight-path Shape Files

Under Geoscience Australia's Onshore Energy Security Program (OESP), Airborne Electromagnetic (AEM) data were acquired in areas considered prospective for unconformity-related and palaeochannel-hosted uranium deposits. The program was aimed at reducing exploration risk and promoting exploration activity. The surveys were designed to reveal new information about regions by acquiring the AEM data at line spacings of one to six kilometres over relatively large areas. As well as enhancing the search for uranium and other energy sources, the survey results will be relevant in exploration for a variety of commodities and other resources, including groundwater. 
This data release contains the flight-paths and survey boundaries for the three AEM surveys conducted under the OESP:

Paterson Province (Western Australia) 
Pine Creek (Northern Territory)
