These data consist of spatial and temporal datasets for 7 different small-scale laboratory experiments of fluid-driven fractures, described in the paper The hidden internal flow dynamics of shear-thinning magma in dikes (Kavanagh et al., 2025, accepted in AGU Advances, March 2025). 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.
