Scientists discover hidden heat beneath Himalayan glacier using Picarro's L2140-i Isotope Analyzer

#CurtinUniversity researchers have uncovered something extraordinary hidden deep within what’s long been called “fool’s gold.” ⛏️ ⚒️⛏️ ⚒️⛏️ ⚒️⛏️ ⚒️⛏️ ⚒️⛏️ ⚒️⛏️ ⚒️⛏️ ⚒️ A new study led by #DrDenisFougerouse from Curtin’s #SchoolofEarthandPlanetarySciences reveals that tiny amounts of gold can be trapped within pyrite’s nanoscale crystal defects — a form of “invisible” gold only detectable using atom probe tomography. This breakthrough, published in #Geology in collaboration with the #UniversityofWesternAustralia and the #ChinaUniversityofGeoscience, could redefine how we explore and extract #gold. Even more exciting, the research points to eco-friendlier extraction possibilities, such as selective leaching — a method that uses fluids to dissolve gold along defect pathways without heavily impacting the surrounding mineral. As global gold reserves decline and environmental concerns grow, discoveries like this mark a major step toward sustainable resource innovation. Congratulations to Dr Fougerouse and the team at The Institute for Geoscience Research (#TIGeR) for advancing both science and sustainability through groundbreaking work supported by the #AustralianResearchCouncil and the Science and Industry Endowment Fund. #Research #Innovation #Sustainability #CurtinUniversity #Geoscience #MiningTechnology #DrFougerouse See more of such information on our linktree: https://lnkd.in/epuTzj54 Subscribe to our newsletter: http://eepurl.com/iLNp0w and stay updated with our activities.

Why do earthquakes happen in places where geology suggests they shouldn’t? A new article from Phys.org explores this paradox by looking at seismic activity in regions like Utah (USA), Soultz-sous-Forêts (France), and Groningen (Netherlands)—areas that textbooks describe as too shallow and “stable” for earthquakes to develop. Conventional wisdom holds that faults in the shallow subsurface strengthen as they begin to move, preventing the kind of stress buildup needed for a quake. Yet, reality contradicts this theory, and the mystery persists. This new research dives into how decades of human activity—like geothermal energy production or gas extraction—may subtly alter subsurface conditions in ways that bypass previous assumptions. By rethinking how and why faults behave the way they do, scientists are uncovering critical new insights into induced seismicity. For professionals in geology, energy, and environmental safety, this study offers fresh perspectives on how we interact with Earth's inner mechanisms.

Our research on rare earth elements is among October’s Top 8 Most-Downloaded Papers of all articles published in the journal Cold Regions Science & Technology (Elsevier). In this paper, titled “Controls on cold-climate critical minerals: Regolith-hosted REE at three polar desert salt ponds (McMurdo Dry Valleys, Antarctica),” we characterize poorly-understood mobilization and concentration mechanisms of the energy-, technology-, and society-critical rare earths. Our findings carry implications for understanding critical metal accumulation both on Earth and beyond, and since published, our work has been featured by media worldwide, including Nuuk Daily News (Greenland), La República (Spain), SSBCrack Defense News (India), AustralianRareEarths.com, The World Barometer (International Raw Materials Observatory), MSN, Phys.org, Earth.com Inc, Geochemical News (Geochemical Society), The European Federation of Geologists, Madrid's Colegio Oficial de Geólogos, Montana's Yellowstone Times, The Helena Times, and Montana State University News.

  Here is my briefing paper: “Integrating Field-Based Geology and Isotope Geochemistry to Constrain Metal Mobility and Ore Formation.” This piece connects my field geology and GIS experience with research in geochemistry and experimental petrology. The paper explores how combining field mapping and isotope analysis can help us better understand how metals move and concentrate in the Earth’s crust: insights that are vital for sustainable mineral exploration and resource management. I’m passionate about bridging field-based data with laboratory science to tackle real-world geological challenges and would love to connect with others who share interests in economic geology, ore deposits, and geochemical modeling. I am inspired by Natural Sciences and Engineering Research Council of Canada (NSERC), Nu Instruments Ltd, Auburn University, Auburn University Department of Geosciences, Laura Bilenker. #Geology #Geochemistry #EconomicGeology #IsotopeGeochemistry #MineralExploration #Research #EarthScience #Sustainability

The Differences Between Sedimentary, Igneous, and Metamorphic Rocks: A Comprehensive Guide Understanding the differences between these three rock types is essential for geologists, students, and anyone interested in the Earth sciences. This article delves deep into each type, explaining how they form, what distinguishes them, and their key characteristics. Read More: https://lnkd.in/dwGG_-cb

🎉 Exciting news! 🎉 We’re proud to announce that our scholar, TIAN GUO, student from the SMILE MSCA‑DN, has just published a peer-reviewed research article in the journal Solid Earth: 🔬 «Constraints on stress tensor from microseismicity at Decatur» (Volume 16, Pages 1121-1135, 2025) – DOI: 10.5194/se-16-1121-2025 In the paper, Tian and co-authors investigate how induced microseismic activity at the Illinois Basin–Decatur Project (CO₂ sequestration site) can be used to constrain the full stress tensor in the reservoir. The work provides valuable insights into fault activation pressures, injection dynamics, and reservoir stability — all key issues for safe, large-scale CO₂ storage. A few highlights: - Use of microseismic source mechanisms in combination with vertical stress gradients and instantaneous shut-in pressure (ISIP) data to invert a full stress tensor. - Estimation of minimum activation pressures required to trigger seismicity on identified fault planes — vital for predicting long-term injection response. - Insights into the importance of high-quality seismic source mechanism data and site-specific stress field constraints for induced-seismicity risk assessment in CCS projects. This achievement reflects Tian’s dedication and the strong support of the SMILE MSCA-DN network. Congratulations to the entire team behind this research — your work is making an important contribution to geosciences and carbon-capture technology. 📖 Read the full article here: https://lnkd.in/dMDtfdNJ 🔗 Also check out the SMILE MSCA-DN outputs page for more on the project’s work: smile-msca-dn.eu/outputs/ Seismik s.r.o.

📣 Geosciences, Volume 15, Issue 10 is online! 📚 Welcome to read all 36 published articles! ➡️ https://brnw.ch/21wX9Vo 📜Cover Article: "Ejecta from the Late Triassic Manicouagan Impact in the Fundy Basin, Canada” 📎 https://brnw.ch/21wX9Vn 📑 Cover story: The Late Triassic (Norian) Manicouagan impact structure in northeastern Canada is one of the largest impact sites of the Phanerozoic, but has a sparse record of ejecta deposits. Sedimentary layers at the top of a seismically deformed zone in playa deposits in the Norian-age Blomidon Formation in the Fundy Basin, 750 km away, contain shocked quartz and spherulitic grains that are interpreted as impact ejecta. The presence of ejecta at the top of the deformed zone suggests that the seismicity resulted indirectly from the Manicouagan impact via reactivation of a nearby fault system. Paleomagnetic correlation of the ejecta-bearing zone to the time scale for the Newark Basin suggests a discrepancy in the correlation of the Newark time scale to the magnetostratigraphic record of the Upper Triassic.
