Geophysical investigation of mine waste in Endurance legacy mine site, northeast Tasmania

Wei Xuen Heng

Endurance legacy mine site was found to have acid and metalliferous drainage (AMD) generated after mine closure, which has impacted rehabilitation success and the local environment. The geophysical approach has been carried out and integrated with on-going hydrogeological and geochemical studies to inform suitable rehabilitation plan.

Flying high – how geophysics can help with finding water in Cobar area

Millicent Crowe

Cobar township, hub to pastoralists and mining, has little room for growth due to its’ limited water supply but the region has two types of palaeochannel systems that are prospective for water. The location and water quality of these potential sources can be identified through the electromagnetic signal from the Cobar Airborne Electromagnetic Dataset from Geological Survey of NSW.

Can neutron tomography detect in-situ density changes?

Vili Grigorova

Neutron tomography is a powerful non-destructive technique used to study the internal structure of objects. As opposed to the X-ray tomography, neutron tomography can penetrate objects made of an element with high atomic numbers. High-pressure apparatus such as the Paris-Edinburgh press are used routinely up to10 GPa and 1500 °C. Adapting such apparatus to be used in a neutron tomography beam will allow us to obtain in-situ 2D and 3D images of samples while held at high pressures and temperatures to induce density changes. My work included (1) a selection of neutron friendly materials for the frame structure of the press and the sample assembly, (2) pressure and temperature calibration of the new sample assembly cell, and (3) image quality analysis of the DINGO beamline.

How to form a world-class bentonite deposit in a volcanic island arc setting: An example from Milos island, Greece

Jo Miles

The interaction of magmatic heat, volatile flux, and surrounding sea and/or meteoric waters can have significant bearing on the nature of the hydrothermal systems in volcanic island arc settings. We integrate field relationships of volcanic stratigraphy and alteration zones, with clay mineralogy by X-ray diffraction (XRD), stable (S-, O- and H-) isotope analysis and high precision geochronology (CA-ID-TIMS zircon U-Pb, and alunite Ar-Ar) to elucidate the timescales and fluid components that lead to the development of a globally important bentonite resource.

Petrophysics database production 101

Andreas Bjork

Confidence in the reliability of scale-consistent quantitative databases of rock properties is key to linking geophysical data with interpreted geology.

This talk is one lab technician’s reflections on one hundred-and-one ways to collect data and with the wish that you could get it right the first time, everytime.

About the GSA

The Geological Society of Australia was established as a non-profit organisation in 1952 to promote, advance and support Earth sciences in Australia.

As a broadly based professional society that aims to represent all Earth Science disciplines, the GSA attracts a wide diversity of members working in a similarly broad range of industries.
