Mechanics and dynamics of magmatic dyke emplacement, including tip zone rupture, segment linkage, and dyke-parallel shear failure are elucidated by high precision digital outcrop analysis. New approaches are derived for the structural analysis of dykes that employ digital photogrammetry and Unmanned Aerial Vehicles to capture 3D measurements at exceptionally high resolution (3-5 mm per pixel) across 5 orders of magnitude (10‾2 to 102 m), which are applied to outstanding exposures of dyke swarms from Albany, southwestern Australia, and the Sierra Nevada, USA and compared analytical solutions from linear elasticfracture mechanics.
