- •
Tight Carrara marble samples were thermally cracked.
- •
Crack network visualized in 2D and 3D using high-resolution imaging techniques.
- •
Crack network independently verified by porosity and NMR measurements.
- •
Permeability increase due to micro-cracks aperture.
- •
Stress sensitivity of permeability is linked to temperature of treatment.
