    54. The Bushveld - Decoding a Mega-magmatic Mineral System

    Dive deep into a mega-magmatic mineral system — the Bushveld Complex with host Maxwell Porter. Max is joined by Professor Wolfgang Maier and Dr. Erin Thompson who share their insights on the geological setting, economic significance, and evolving scientific understanding of this world-class mineral province. Wolfgang Maier discusses the Bushveld Complex’s geological framework, its importance in today’s resource landscape, and the controversies surrounding models for its genesis — and how these models have shifted over time. Wolfgang Maier completed his PhD on the Bushveld at Rhodes University, South Africa in 1992. He taught igneous petrology and economic geology at the Universities of Port Elizabeth, Pretoria (South Africa), Chicoutimi (Canada), UWA (Perth, Australia) and Oulu (Finland). He is now Professor for Ore Geology at Cardiff University, UK. Wolf’s research deals with petrological and geochemical processes in mafic-ultramafic igneous systems that contribute to our understanding of continental magmatism, mantle evolution, plate tectonics and the formation of magmatic ore deposits including PGE, Ni-Cu, Cr, and V-Ti-Fe deposits.  Erin Thompson shares what drew her to study the northern limb, why it holds both geological and economic importance, and how magmatic architecture and mineralisation controls shape exploration strategies. She explains the once-overlooked yet powerful tool of Niggli numbers, and how geochemistry and isotope studies inform exploration and the future of the Northern Limb. Dr Erin Thompson has recently completed her PhD at the University of Leicester, which focused on constraining the magmatic controls on Ni-Cu-PGE mineralisation in the world-class Platreef deposit, northern limb of the Bushveld Complex. Her research was funded by Anglo American as part of the Northern Limb in 4D (NL4D) research consortium, which included researchers from across the UK at the University of Leicester, Cardiff University and Camborne School of Mines. She is now applying her background in magmatic processes and geochemistry in her new role as an exploration geologist. Theme music is Confluence by Eastwinds eastwindsmusic.com

    SEG 2024 Student Chapter Challenge 2: Evolution of Geology in Brazil to the Mineral Potential of Northern England

    We are thrilled to bring you the top entries from the 2024 SEG Student Chapter Podcast Challenge as a special set of three episodes.  This second episode in the mini-series pairs the 2024 Silver the intriguing stories and history shared by an esteemed geologist in Brazil, with a second segment that uncovered the history and mining potential of northern England.  Chapter 1:  Title: The Evolution of Geology in Brazil with Reinhardt Fück SEG STUDENT CHAPTER – University of Brasilia Hosts:  Amanda Rompava and Gustavo D’Amore Heer Producers:  Juliana Berbert and Mariana Guest:  Professor Reinhardt Adolfo Fück The theme of this episode tells the story behind the articles and mapping work of one of Brazil's greatest geological characters, with special emphasis on the magmatic arc of Goiás in the Brasília belt, where important deposits reside, as well as his significant work on crustal structure, the Tocantins Province, and Goiás Massif. With a cautious eye and carrying the experience of working with geology since the 1960s, Professor Reinhardt shares with us the unwritten history behind published articles, his perspecitve on the evolution of knowledge in the field and also the importance of mapping for a geology career. Chapter 2:  ‘The Critical Mineral Potential of the North of England’ SEG STUDENT CHAPTER NAME:  University of Leeds Hosts, Lily Dickson and Brayden Pickard  Guests:  Dr. James Shaw  (structural geologist) and Adam Eskdale (Rio Tinto) provides an overview of mineral exploration and extraction in our region of the UK, the North of England (Figure 1) and its critical mineral potential.  In February 2024, our student chapter hosted a mini-conference on the subject of critical minerals (Figure 2) with talks from companies including British Lithium, the Critical Minerals Association (UK) and Green Lithium. We were inspired to carry out further research into the critical mineral potential of the region we live in, the North of England, which we present in this podcast. At present, the UK does not extract any of the 18 critical minerals on the 2021 list published by the British Geological Survey (BGS). This renders the UK completely reliant on international supply which is a big problem, and one that we must try to address through increased mineral exploration and mining in the near future.  In order to provide a full picture of the critical mineral potential of our region, we explore the rich mining history of the North of England, dating back to the Bronze Age at sites such as Alderly Edge (Figure 3). We also investigate current critical mineral projects: Li exploration around the Weardale Granite and Potash mining near the town of Whitby. Finally, we speak to Dr James Shaw and Dr Adam Eskdale who have worked on fluorspar mineralisation in the South Pennine Orefield and cobalt mineralisation in the Lake District, respectively. They provide insights into these deposits and to potential barriers to their extraction in the future.  A big thank you goes to Dr James Shaw and Adam Eskdale for sharing their expertise with our student chapter!  Come join us in Brisbane, Australia for SEG 2025, September 26-29th.  This will be a dynamic conference with cutting edge science, new discoveries, technology and more.  Opportunities for networking and learning include several workshops and field trips before and after the event, relaxed social events and of course the conference itself.  See you there!

    SEG 2024 Student Chapter Challenge 1: Mining Challenges from Greenland to the Deep Sea

    We are thrilled to bring you the top entries from the 2024 SEG Student Chapter Podcast Challenge as a special set of three episodes.  This episode pairs the 2024 Bronze winner with another that explored some of the political and environmental challenges in developing mineral deposits.   Chapter 1:  The deposit that brought down a government SEG STUDENT CHAPTER NAME: The Pennsylvania State University (Penn State) Co-hosts:  Rory Changleng, Alex Cerminaro  Producer: Rory Changleng  Chapter Notes  What mineral deposit became such a politicised commodity that it brought down a government? In this episode, two Penn State students, Rory and Alex, discuss what got them into geology and inspired them as budding economic geologists to begin a new SEG Student Chapter at Penn State. Alex reminisces about how trying to discover gold in his grandmother's garden in Pennsylvania led to his working with an Alaska exploration company to date gold mineralisation using a novel geochemical technique. Rory tells the story of the Ilimaussaq intrusion in Southern Greenland, home of the Kvanefjeld deposit. It was visiting this deposit during undergraduate fieldwork that opened his mind to the turbulent and consequential world of economic geology. Exploiting Kvanefjeld proved so divisive that it drove the collapse of the Greenlandic government. But as the second largest rare earth element deposit on Earth, surely it’s just a matter of time until mining begins? Chapter 2:  Should we Mine the Seafloor?  SEG STUDENT CHAPTER NAME: SEG of Athens  Host: Pavlos Zambras Guests:  Evi Dimou and Revekka Avoukatou Chapter Notes  Exploring the depths of the ocean for valuable resources presents an alluring frontier in human endeavor: Deep Sea mining. This venture entails a journey into the unknown, facing both mysteries and challenges while uncovering the potential of extracting precious materials from the ocean floor.  The vast expanse of the deep sea, encompassing more than 65% of Earth's surface, harbors immense reservoirs of base metals, precious metals, and critical elements like nickel, copper, cobalt, and manganese. These elements are indispensable for powering the transition towards clean green energy. Whether it's polymetallic nodules or seafloor massive sulfide found at hydrothermal vent fields, these resources offer the promise of driving technological progress and fostering economic development in the years ahead.  However, the pursuit of these underwater treasures is not devoid of controversy. Deep sea mining raises profound concerns regarding its environmental impact, sustainability, and the ethical utilization of Earth's resources. It's crucial to acknowledge that these deep-sea environments host unique life forms not found elsewhere on the planet, including highly complex prokaryotic communities and microbes with exceptional tolerance to acidity and antibiotics.  International regulations governing deep sea mining are still under development, adding to the uncertainty surrounding this practice. Many fear the potential ecological disruption it could bring to an area of our planet that remains largely unexplored. The question arises: Can we afford the environmental and ecological risks associated with deep sea mining? Or, put more simply, should we proceed with mining the seafloor?  Come join us in Brisbane, Australia for SEG 2025, September 26-29th.  This will be a dynamic conference with cutting edge science, new discoveries, technology and more.  Opportunities for networking and learning include several workshops and field trips before and after the event, relaxed social events and of course the conference itself.  See you there!
