Geological Survey of South Australia’s Post

This is an excellent review of key Drillholes and samples from the Curnamona by Diana Zivak . A must read for anyone interested in critical metals and especially, rare earth elements.

Another report coming out of #GSSAs Critical Mineral project. Great work by Diana Zivak on characterising the REE associated mineral system styles in the Curnamona Province. #REE #criticalminerals #southaustralia

Today’s video is about the “Critical minerals prospectivity of the Musgraves Province in South Australia” - Part seven of our Critical Mineral Monday series. 📽️ https://ow.ly/YkvL50Tixms Assessing historic drill core from the remote Musgrave Province in the far north-west of South Australia is providing new opportunities to review the critical mineral potential of this region. In our latest video, Dr Alicia Caruso explains her work collecting new data sets from legacy drill core provided by external organisations and explorers to the state’s Drill Core Library. As we advance into a digital era, interest is shifting to a new generation of resources that may be hidden in these remote regions. While past explorers might not have targeted elements like graphite and vanadium, the Critical Minerals South Australia (CMSA) project is now analysing a diverse range of samples - geochemistry, geochronology, and petrology - alongside integrating HyLogger data. This comprehensive approach aims to reveal the Musgrave Province’s potential for critical minerals.

How are magmatic and brine melt processes refleced by apatite and pyrochlore mineralchemistry? Interested? See our latest publication which is part of the phd project of Mohsin Raza. Well done Mohsin!

I am pleased to share that my first article, "The Magmatic to Post-Magmatic Evolution of the Nooitgedacht Carbonatite Complex, South Africa," has been published as part of my PhD research. This research introduces new age data, highlights the reuse of the same magmatic path during ascent, and provides detailed insights into the processes of critical metal enrichment in carbonatites. Thank you to everyone who supported me in this journey! Check it out to explore the fascinating insights into carbonatite evolution and mineralogy! https://lnkd.in/gzA-SPaa #Geochemistry #Carbonatite #RareEarthElements #Mineralogy

Ever wondered how rare earth elements (REEs) are concentrated in certain geological deposits? A study published in Ore Geology Reviews sheds light on the formation of the Lizhuang carbonatite-associated REE deposit in southwest China, providing new insights into the role of recycled oceanic components and volatiles. Key takeaways: 💡The Lizhuang syenite, part of the Mianning–Dechang REE belt, formed about 27 million years ago in a post-collisional setting. 💡The mantle source of the deposit was enriched by subducted marine sediments and altered oceanic crust, leading to the concentration of REE and volatiles. 💡The study utilized in situ Hf–O isotope analysis, mineral chemistry, and geochronology to understand the petrogenesis and volatile evolution of the syenite. 💡The findings suggest that the upwelling of asthenosphere and the reactivation of the cratonic root played crucial roles in the formation of the REE-enriched parental magmas. The research provides valuable insights into the formation of carbonatite-associated REE deposits, which are critical for high technology industries.

The study of Louis Coetzee et al. documents for the first time details of the #mineralogy and #chemistry of the #Avontuur deposit, a prominent outlier of the #Kalahari Manganese Field, the world’s largest land-based #manganese deposit that is located in the Northern Cape Province of #SouthAfrica. The paper documents remarkable similarities in #geological architecture, but profound differences in mineralogy between the mangano-lutites of the Avontuur and the main Kalahari deposit. These differences are tentatively attributed to systematic lateral variations in #physicochemical conditions of mineral precipitation during the deposition of the manganiferous sediments just prior to the Great Oxidation Event, e.g., the time at which the Earth’s atmosphere became markedly enriched in oxygen for the first time in Earth’s History. #geoscience 👉 to the paper: https://lnkd.in/eFjwZXtT

🎉 NEW REPORT 📖 Geochemistry of drill core samples from the Stuart Shelf region, South Australia - Data release 2 🙂 D.C. Champion, D.L. Huston, E. Bastrakov, A. Fabris, C. Krapf, S. Gilmore, J. Byass, I. Long and S. Webber 🏦 Published by Geoscience Australia 🔗 https://lnkd.in/gTP4JdA2 The 'Geochemistry for Basin Prospectivity' project is part of Geoscience Australia's Exploring for the Future (EFTF), focusing on studying Australian basins with potential base metal mineral systems. In collaboration with the GSSA, this project investigates the baseline geochemistry of the Stuart Shelf and complements the GSSA-CSIRO project 'Sedimentary Copper Mineral Systems of the Stuart Shelf (read more: https://ow.ly/MULa50PLpIL). This report discusses all the final results from the project, and releases all the geochemical data collected from across the Stuart Shelf. In total, 888 drill core samples from 22 drillholes were analysed, targeting units from the Neoproterozoic sedimentary succession and underlying basement units. This data indicates the Wallaroo Group, Donington Suite, units of the Callanna Group, and the Tapley Hill Formation have good source rock potential with regards to sedimentary base metal systems. #SedCu #Copper #StuartShelf #EFTF #GeoscienceAustralia #Geoscience #Geology #Geochemistry #Minerals #MineralSystems #CSIRO
