Rocks under pressure with Tim Chapman from LLUNE

This is the second of three special episodes in partnership with the Litho Lab University of New England or LLUNE for short. Have you ever felt under a lot of pressure? Well, Dr. Timothy Chapman from LLUNE chats with Dr. B about rocks that formed at very high pressures (HP), way higher than the one of your pressure cookers! Tim talks about pressures higher than 1 GPa, which corresponds to depths of c. 40 km and deeper. Beautiful, colorful, and characteristic HP minerals form at these conditions, down the Earth, in tectonic environments such as subduction zones. Tim talks also about a recent research paper of his, where he investigated the mechanisms that bring these rocks back to surface (or exhume) and allow researchers like him to study important processes that happen at great depths. This episode is sponsored by Litho Lab University of England (LLUNE).

Host Information:

Dr. Vitor Barrote: A member of the Traveling Geologist team and the host for Gneiss Chats on the Geology Podcast Network. Vitor, also known as Dr. B, has a PhD in applied geology from Curtin University. His current research focus is on analytical developments in geochemistry and geochronology, but he has a soft spot for Economic Geology, also. He enjoys multidisciplinary studies that apply unorthodox and innovative solutions to resolve unusual problems. He is a big fan of spreading education through inclusive media, with science outreach efforts such as this podcast series. He also holds an (honorary) PhD in geological dad-jokes.

Dr. Silvia Volante: A member of Traveling Geologist team, producer and occasional co-host for Gneiss Chats on the Geology Podcast Network. Silvia also has a PhD in applied geology from Curtin University. She loves to explore the different pressures, temperatures and compositions conditions at which igneous and metamorphic rocks formed. Her favorite word? Unravelling! Unravelling the evolution of basement rocks by mapping them in the field, as a good old-fashioned field geologist would do, and investigating the record incapsulated in minerals that define ductile fabrics and, why not, that can also be dated!

Producer Information:

Dr. Bryant Ware: Dr. Ware is a geology researcher (an isotope geochemist, and geochronologist for those who want to know exactly) at Curtin University in Western Australia. He knows all about the nitty gritty details of the geochemical analysis of rocks to produce the data that help us to understand the processes that shape our planet. Despite spending an excessive amount of time in the clean lab, he loves the outdoors and spending time in the field. As a member of the Traveling Geologist Team, and producer on Gneiss Chats from the Geology Podcast Network he enjoys sharing his excitement about geology with others.

Dr. Francesca Miozzi: Francesca has a PhD in planetary geology from Sorbonne University. She is an experimental mineral physicist and petrologist who enjoys squishing and heating minerals to extreme pressures and temperatures, to investigate the mysteries of planetary interiors. She is also a member of the Geology Podcast Network’s Gneiss Chats and Traveling Geologist.
