W ramach Seminarium fizyki kosmicznej referat pod tytułem Modelowanie deformacji skorupy wywołane intruzją magmy na skalistych ciałach planetarnych
wygłosi: dr Sam Poppe
Będzie to oficjalna inauguracja projektu NCN, eng: DeMo-Planet: A new project to simulate shallow magma emplacement in the fractured crust of Earth, the Moon and Mars.
Dr. Sam Poppe is a structural geologist and volcanologist. He holds a PhD from Vrije Universiteit Brussel (Belgium), where he investigated magma intrusion processes in non-elastic media by combining analogue sandbox experiments with medical X-ray Computed Tomography. He has been a Fulbright-BAEF fellow at Penn State University (USA) where he tested the accuracy of geodetic inversion models with experimental sandbox results, and worked as a postdoctoral researcher at Université libre de Bruxelles (Belgium) on the mechanical interaction between magma intrusion and tectonic extension. He has also been involved in volcanic hazard studies and field work in the East-African Rift (DRC, Rwanda, Comoros) and is an awarded and passionate science communicator to a broad audience. He is now a visiting scholar under the ULAM programme of the Polish Agency of Academic Exchance (NAWA) at the Space Research Centre PAS in Warsaw, leading the DeMo-Planet project funded by NCN-Poland.

Streszczenie: Most numerical models that are commonly used to investigate magma emplacement and forecast volcanic eruptions, assume that the shallow crust of terrestrial planets deforms elastically. In contrast, geological observations and analogue experiments have often shown that magma-induced deformation can be non-elastic. Because of the potentially important implications for volcano forecasting on Earth, we need to answer the question how realistic and accurate elastic models are in representing magma emplacement processes. DeMo-Planet is a newly-funded project at the Mars Exploration Laboratory of SRC PAS, that aims to develop a new application of simulating the emplacement of high-viscosity magma in the shallow crust of planetary terrestrial bodies in a Distinct Element Method (DEM) model. In this seminar, Dr. Sam Poppe and colleagues will lay out the current understanding of magma emplacement processes and associated crustal deformation, and how DeMo-Planet aims to contribute a new magma emplacement model. By combining field observations in the Intra-Sudetic Basin in South Poland, laboratory tests of mechanical rock properties, with remote sensing observations of magmatic uplift features on the Moon and Mars, the international consortium of the project aims to inform a new numerical model that, in the end, may progress our understanding of non-elastic deformation during magma emplacement on the Earth, Moon and Mars.
