The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Resistivity of typical rocks at crustal pressure and temperature conditions from combined laboratory and magnetotelluric measurements. Magnetotelluric surveys are playing an increasing role in Australian geoscience, including academic research, data collected by geological surveys (including a role in Geoscience Australia's $58.9 million Onshore Energy and Security Program), mineral exploration and geothermal exploration.

Magnetotelluric surveys are playing an increasing role in Australian geoscience, including academic research, data collected by geological surveys (including a role in Geoscience Australia's $58.9 million Onshore Energy and Security Program), mineral exploration and geothermal exploration. This project will enable the results of these surveys to be interpreted more accurately and meaningfully by constraining the expected resistivities of crustal rocks at various pressures and temperatures. This research is vital if the investment currently being put into MT surveys is to be capitalized upon. Read moreRead less
Nickel iron sulphide mineralogy: the link between mineral transformations and microstructure and magnetic properties. This project is about measuring the rate at which minerals transform or react and how metal diffusion controls these reactions. Metal diffusion in sulphides is much more rapid that in silicates and is still very significant at low temperatures (< 300 C). In this project, we are trying to measure the rate at which the principal ore of nickel, pentlandite, transforms to violarite ....Nickel iron sulphide mineralogy: the link between mineral transformations and microstructure and magnetic properties. This project is about measuring the rate at which minerals transform or react and how metal diffusion controls these reactions. Metal diffusion in sulphides is much more rapid that in silicates and is still very significant at low temperatures (< 300 C). In this project, we are trying to measure the rate at which the principal ore of nickel, pentlandite, transforms to violarite, another important nickel rich sulphide that forms from it in the upper parts of ore bodies. The arrangement of the metal atoms in these minerals is sensitive to temperature, so it may be used as a geothermometer.Read moreRead less
Linkage Infrastructure, Equipment And Facilities - Grant ID: LE100100236
Funder
Australian Research Council
Funding Amount
$180,000.00
Summary
Facilities for spectroscopy and diffraction at high pressures. The provision of infrastructure for the study of novel materials under high pressures will enhance Australia's capability in creating new materials and in creating new devices that meet needs in communication, environment and medicine applications. The new facility will enable researchers to understand the response of structures to extreme pressures and will exploit the unique capabilities of the synchrotron light.
