Data for: Wall fracturing versus mechanical instability as competing intrusion mechanisms of dikes: Insights from laboratory experiments

Igneous dike intrusion is a primary crust-forming process. Understanding its governing mechanism is very crucial for studies related to the lithosphere. We performed liquid injection experiments in the laboratory with two new crust analog model materials, i) ultrasound transmission gel (USTG) and gel wax. To conduct a properly scaled model experiment, we test their rheology using an Anton Paar M302e rheometer. The measured rheological data were presented in this present data repository. We identified three mechanisms from our laboratory studies: a) fracturing, b) interfacial instability, and c) hybrid, i.e., a combination of both. These three mechanisms give rise to distinct 3D geometries. To quantitatively analyze their geometric shapes, we performed fractal, aspect ratio, and skewness-kurtosis analysis. The procedure and the data collected during the analysis were also presented in the current data repository. ,
For the field map, data was collected in the form of handwritten notes and plotted on white plain paper. Then traced using CorelDraw Software. 
We use a high-speed camera and volume calculator for the volumetric flow rate calculation.
For fractal dimension and Skewness-Kurtosis data acquisition and calculation, MATLAB and OriginPro were used.
Rheology measurements are done via Anton Paar Rheometer (M302e).
