Darley Dale sandstone sample tts6, deformed under true triaxial stress, was scanned via X-ray CT at the University of Aberdeen in 2019. The dataset captures the internal structure of a 50 mm cube sample that underwent two distinct deformation tests, producing brittle microcracks. The data was collected by Dr Stewart Chalmers and Dr Dave Healy and is associated with the British Geological Survey.
Use Cases
- Analyze 3D fracture patterns from X-ray CT scans to correlate with acoustic emission events from deformation tests.
- Model the propagation of brittle microcracks detected in the scan data relative to applied stresses in the 1, 2, and 3 directions.
- Use the CT scan dataset to validate seismic velocity analysis results from the deformed sandstone sample.
Strengths
- Captures the internal structure of a physically deformed 50 mm cube sandstone sample.
- Data is linked to specific, documented true triaxial deformation experiments (tests DDSS0009 and DDSS0010).
- Scans were performed by named researchers (Dr Stewart Chalmers and Dr Dave Healy) at a known institution (University of Aberdeen).
Limitations
- The dataset is a single scan of one specific sandstone sample (tts6), limiting statistical generalizability.
- No columnar or tabular metadata is provided, restricting quantitative analysis without further processing.
- The scan data's resolution, file format, and size are unknown, complicating immediate usability.
