However, the record of Precambrian impacts is poorly constrained due to the dynamic nature of plate tectonics, erosion and deposition of younger rocks, which may destroy or cover the evidence of ancient impacts. After delivering a presentation on their recently completed Digital Mineralogy Library project, the Jd LC hosts invited their visitors to offer feedback and discuss opportunities for new projects to further assist researchers in managing and disseminating high-value geochemistry datasets.

The reidite was discovered using advanced mineral characterisation technologies housed in the John De Laeter Centre (Jd LC) at Curtin University. The response was positive with many participants sharing their views on the importance of data management and discovery, and recognising the contribution that the Jd LC has made in this area.

A team of Curtin University geoscientists has discovered the earliest known occurrence of reidite, one of Earth’s rarest minerals.

At 1.2 billion years, the finding is more than double the age of the previous oldest known occurrence at 450 million years. Distributions and compound-specific isotopic signatures of sedimentary chlorins reflect the composition of photoautotrophic communities and their carbon and nitrogen sources in Swiss lakes and the Black Sea Nasdala, L., Corfu, F., Valley, J.

The hardware component of the project was funded via the Australian Research Council with support from Curtin University, the Geological Survey of Western Australia, University of Western Australia and Murdoch University. One avenue being considered is the public documentation of WA’s mineral resources. J., Curran M., Edwards R., Faluvegi G., Ghan S., Horowitz L.

The project is being jointly run between the John de Laeter Centre, Curtin University Library and Curtin Information Technology Services. Journal of Analytical Atomic Spectrometry, 29, 981-989. It is hoped that by allowing free, open access to this information, further interest in developing domestic mineral reserves will be stimulated and create a more varied and sustainable mineral economy.

The MMF is involved in the creation of the Digital Mineralogy Hub facility which is using cutting-edge scanning electron microscope technology to construct a mineralogical and geodata library for the Australian continent. We are currently involved in an exciting new project with CSIRO and UWA called the Advanced Resource Characterisation Facility which will bring new atom probe and ion beam technology to Western Australia.

This will foster a richer scientific understanding of our country and promote new discoveries. Data from the financial year 2013-2014 indicates that Western Australia’s (WA) minerals and energy output alone was worth 2bn for the year, dominated by iron ore, which accounted for approximately 60% of the sector’s income. 100-80Ma) magmatic "flare-up" in southern Lhasa (Tibet)SHRIMP U-Pb zircon age for the Segwagwa-Masoke Igneous Complex of southeastern Botswana and implications for the deformation history of the Achaean to Proterozoic Transvaal Supergroup of southern Africa Using zircon u-pb ages and trace element chemistry to constrain the timing of metamorphic events, pegmatite dike emplacement, and shearing in the Southern Parry Sound Domain, Grenville Province, Canada Resilience of cold-water scleractinian corals to ocean acidification: Boron isotopic systematics of p H and saturation state up-regulation.

DOWNLOAD THE NEWSLETTER Curtin University researchers have for the first time been able to visualise where helium atoms are trapped within individual mineral grains, providing information that can help to determine the geological history of the Earth’s crust and assist in monitoring natural hazards like earthquakes and volcanic eruptions.

November to demonstrate the application and benefits of automated mineralogy to the minerals industry and academic research.

Welcome to the first edition of Wavelength – A quarterly newsletter dedicated to highlighting the latest news and research produced from Curtin’s X-ray characterisation facilities, namely the X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD) and small angle X-ray scattering (SAXS) facilities.

As a special first edition feature, we have included an entire page that highlights the basic instrument capabilities of each facility. See poster for more about Digital Mineralogy Library. This equates to almost 65% of Australia’s national output, with minerals being Australia’s major export earner. * The Digital Mineralogy Library project is supported by the Australian National Data Service (ANDS) and Au Scope through the National Collaborative Research Infrastructure Strategy Program. The collapse of iron ore prices to below /tonne, down from a peak of 0/tonne four years ago, has hit WA hard and the state is now urgently seeking ways to stimulate its mineral sector and diversify its resource base away from iron ore. Working with the University of St Andrews, the team, led by Professor Steven Reddy from the Institute for Geoscience Research at Curtin’s Western Australian School of Mines, discovered the reidite in shocked zircon from impact ejecta at Stac Fada in Scotland.
