These experiments, conducted at the University of Liverpool, are analogue models of magma transport via flux-driven dykes. The 7 experiments are named HEC1, HEC2, HEC3, XG1, XG2, W1, W2. Experiments HEC and XG involved the injection of a shear-thinning fluid (a hydroxyethyl cellulose polymer (HEC) and xanthan gum solution (XG)), whilst experiments W1 and W2 involved Newtonian water injections. Experiments HEC1, HEC3, XG1 and W1 were ‘seeded fluid experiments’ or ‘PIV experiments’, whilst experiments HEC2, XG2 and W2 were ‘seeded gelatine experiments’ or ‘dyke-thickness experiments’. We provide the raw experimental data along with the Matlab scripts used to process and plot the data. Further information is provided in the containing README documents.

Constant fluid injection resulted in the formation of a thin penny-shaped fracture that grew until it erupted at the surface. The plane of fracture growth was illuminated with a thin laser sheet to visualise fluorescent seeder particles that were suspended in either the fluid or the gelatine. Fracture and flow evolution were recorded with a camera placed perpendicular to the laser sheet. For the seeded fluid experiments, a particle-tracking technique called Particle Image Velocimetry (PIV) was applied to get 2D fluid velocity profiles across the fracture width at regular time intervals. The seeded gelatine experiments were recorded in the alternative plane, perpendicular to the plane of the seeded fluid experiments, to visualise the evolution of the fracture thickness.
