HEC/XG/W Experiments: Small-Scale Analogue Dyke Data

Seven laboratory experiments (HEC1, HEC2, HEC3, XG1, XG2, W1, W2) conducted at the University of Liverpool, described in a 2025 paper. The data consist of spatial and temporal measurements from analogue models of fluid-driven fractures, comparing shear-thinning and Newtonian fluids. Raw data and Matlab processing scripts are provided by the British Geological Survey.

Use Cases

• Compare fracture propagation dynamics based on shear-thinning versus Newtonian fluid properties
• Validate numerical models of dyke emplacement using the provided spatial and temporal datasets
• Analyze internal flow dynamics in analogue experiments using the Particle Image Velocimetry (PIV) data
• Study the relationship between fluid injection and dyke thickness evolution in seeded gelatine experiments

Strengths

• Includes data from 7 distinct, named experiments allowing for controlled comparisons
• Provides raw data alongside the specific Matlab scripts used for processing and plotting
• Covers two fluid rheology types: shear-thinning (HEC, XG) and Newtonian (water)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count and file size are unknown, which may limit suitability assessment
• Data may reflect experimental bias inherent to the specific small-scale laboratory setup
