Talking geoscience

A week of information sharing.

Discovery Day is fast becoming Discovery Week! In 2018 the annual Geological Survey of South Australia (GSSA) Discovery Day will be preceded by two major workshops run by GSSA to be held at the South Australia Drill Core Reference Library. In these two one-day workshops, geophysics will be taking centre stage as GSSA unveils the results of two major geophysical data acquisition programs. With a full program in each and spaces limited, be sure to register for these free events individually following the links provided. Also listed are two other related geoscience events being held in Adelaide in the first week of December.

Tuesday 4 December Gawler Craton Airborne Survey (GCAS) workshop
Wednesday 5 December Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) workshop
Wednesday 5 December Geological Society of Australia Earth Sciences Student Symposium in South Australia
Thursday 6 December Discovery Day
Friday 7 December South Australian Exploration and Mining Conference

Discovery Day

Discovery Day is the premier event for the GSSA and collaborating organisations to deliver data and its geoscientific value to our stakeholders, in particular the minerals industry. This year the wide range of activities of the GSSA will be covered, in particular, the results of recent geological mapping in the central Gawler Craton region, geochemical investigations into the mantle beneath the Gawler Craton and a summary of commodity trends viewed from a South Australian perspective. In addition, we will be having a panel session that looks at the emerging technologies for non-destructive analysis of geological material relevant for mineral exploration.

Discovery Day will also feature an exhibition space with posters and interactive displays of South Australian geology and recent geoscience, including a review of the geology and tectonics of the Kanmantoo Group in the east of South Australia, new geophysical datasets from GCAS. The South Australian Museum exhibit is sure to be a favourite with some spectacular minerals from South Australia on show.

Gawler Craton Airborne Survey workshop

Tuesday 4 December, South Australia Drill Core Reference Library

The 1.67 million line kilometre GCAS is the largest airborne magnetic–radiometric – digital elevation model survey in South Australia’s history, providing magnetic and radiometric data at a scale and level of detail never before seen in regional geophysical data acquisition by the South Australian government. The GCAS project team has collaborated closely with Geoscience Australia, GCAS contractors and experts in the fields of magnetics and radiometrics to ensure that current best practices are followed for the duration of the acquisition and that the range of GCAS deliverables have the potential to reinvigorate mineral exploration in the Gawler Craton.

The aim of this workshop is to demonstrate the utility of the new GCAS datasets and value-added products by bringing the principal project participants together with industry and other agencies who have an interest in the project and products to discuss methodologies, interpret the results and deliver the roadmap for the remainder of the GCAS acquisition and data releases. The complete package of project management, quality control framework and enhanced deliverables have value to other jurisdictions as it sets new standards in magnetic–radiometric–elevation data capture and delivery.

Australian Lithospheric Architecture Magnetotelluric Project workshop

The national UNCOVER strategy identified the collection of a national network of magnetotelluric (MT) data as one of the highest priorities for the Australian geoscientific community. AusLAMP is a collaborative national MT project focused on acquiring long-period MT data at approximately 2,800 sites across Australia at about 50 km spacing.

The aim of this workshop is to celebrate the success of AusLAMP by bringing the MT community of Australia together with all interested in understanding the lithospheric architecture of the continent, to discuss the methodology, interpretation and future progress of this important geophysical method and associated datasets.

The workshop will also celebrate the completion of the South Australian portion of AusLAMP and the release of this new MT data. Magnetotellurics has the capacity to provide an unprecedented insight into the architecture of the Australian continent and its mineral systems. This insight is revolutionising the way in which mineral exploration is conducted and this workshop will explore the key outcomes of AusLAMP.
