Understanding how dykes behave as they propagate through the Earth’s crust has been a hot topic for VIPS researchers for many years–to see how magmatic intrusion models have evolved over the past century check out Tim Davis’ blog post! Through numerically modelling a planar three-dimensional (3D) fluid-filled fracture, mine and Lecampion’s research aims to provide insights into dyke emplacement mechanisms and the evolution of their shape.
