Modelling Magma Movement: Unexpected Journeys in the Field and Lab

Explore a comprehensive lecture on modelling magma movement, covering unexpected discoveries in field research and laboratory experiments. Delve into the Liverpool MAGMA Lab approach, examining scaled analogue experiments, dyke geometry, and surface deformation. Learn about advanced techniques like the Medusa LaVision Laser System and Particle Image Velocimetry (PIV) for analyzing dyke flow velocity. Investigate the scaling of experiments using Reynolds numbers and explore the complexities of magma as a multiphase fluid, including the effects of crystal proportion, shape, and bubbles. Examine the modelling of complex magma rheology and the unexpected findings regarding shear-thinning behavior in magma analogues. Discover how different flow regimes in dykes might be expressed in solidified magma and explore sill geometry, strain rates, and flow patterns. Conclude with a summary of key findings and insights into future research directions in the field of magma movement modelling.
