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.

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.
• Prof Brent Mc Innes (Curtin Jd LC), who demonstrated the applications of the TIMA to Archeology, Petrology, Geochemical Mapping, and the Characterisation of Mineral & Petroleum Systems.
• Kellie Jones (Northparkes Mines), who discussed the application of the TIMA to mining and mineral processing at the Northparkes Cu-Au operation.
Minor amounts of 1660–1330 Ma detrital zircons may have derived from the North American and/or Baltica cratons connected to the northern margin of the North China Craton in the Columbia supercontinent.
The youngest detrital zircon age peak of ∼1337 Ma in the upper Huade Group suggests that the sedimentation began after ∼1.34 Ga.
November to demonstrate the application and benefits of automated mineralogy to the minerals industry and academic research.
Around 35 people from various research institutions, service providers and the mining industry attended the workshop from across Australia. 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. 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. Another example of an eclogite sample from the French Massif Central illustrates the frequent mistake in the interpretation of the ages of the early hydrothermal alteration of zircons in the oceanic crust versus partial or complete recrystallization during eclogite facies metamorphism.Tags: Adult Dating, affair dating, sex dating
