Re os dating sulfides
Thanks to all at Curtin and AXT staff who were involved in the workshop. Special thanks goes to Petrina Beeton who organised the venue, catering and parking.
A team of Curtin University geoscientists has discovered the earliest known occurrence of reidite, one of Earth’s rarest minerals. “It is a breakthrough discovery that will help determine terrestrial impact events which have had a profound influence on Earth’s geological, geochemical and biological evolution.” Deputy Vice-Chancellor Research and Development Professor Graeme Wright said Curtin is at the forefront of high-impact research and development in minerals and energy sectors. “In recent years our research activity, particularly in geosciences, has grown significantly, driving Curtin’s rapid rise up the international university rankings,” Professor Wright said. On the 8th July 2015, staff at the John de Laeter Centre (Jd LC) hosted a two-hour workshop to discuss current and upcoming projects focused on geochemistry data discovery. The Centre is open to collaborative research projects, non-collaborative access to the equipment by qualified users for research purposes, and commercial services. 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. 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.

Professor Reddy used a technique called electron backscatter diffraction (EBSD) to effectively discriminate between reidite and its compositionally identical host zircon. Dr Lesley Wyborn (NCI) was "pleased to see the Jd LC and the community making progress in achieving what [she] has been trying to achieve for the last 30 years in Australian Geochemistry Laboratories ". Analytical pyrolysis for determining the molecular composition of contemporary monosulfidic black ooze.
The discovery paves the way for developing reidite as a proxy for meteorite impact events that can be extended back in geological time to provide insights into Earth’s early impact record. Tulipani, S., Grice, K., Greenwood, P., Schwark, L., Haines, P. Jd LC is looking forward to expanding its data delivery services to include geochemistry data from its Sensitive High Resolution Ion Micro Probe (SHIMP) and laser ablation instruments in the future. As the downturn in mineral prices continues to drag on Australia’s economy, a project led by Perth’s Curtin University is seeking to create an open access digital mineral inventory of WA that it hopes could stimulate interest in further exploration in the state.

Professor Reddy’s discovery has been published in the prestigious Geology journal and can be viewed Chemical Geology. Through collaborations with state and national organisations and businesses this project will see more data being made readily available to researchers, industry and the public.

In this work, we also discuss how recent discoveries have provided new insights into the processes underpinning the global rise in atmospheric oxygen and the geochemical evolution of the oceans.
The John de Laeter Centre provides quantitative data used to understand processes of Earth and planetary evolution, characterise the nature of resources and materials upon which our society depends, and monitor our changing environment. K., Aeppli, C., Samuel, J., Chen, H., De Oliveira, A.
Perhaps one of the most significant events was the transition from an anoxic planet to one where oxygen was persistently present within the marine water column and atmosphere.
