Task 1-2 : Microstructural analysis [ISTerre, IC2MP]
Objectives :
Quantify the damage (fracturing intensity) and deformation experienced by the analysed samples.
Description of planned work :
Damage is more pervasive on Nojima, which will be the main focus of this work. Fracturing and fracture offsets will be quantified on the selected thin sections. X-Ray CT scan will allow identify fractures in 3D at the voxel size (10μm-100μm size depending on the sample size) and through segmentation, identify interconnected fracture network and extension of mineral phases.
| Analysis | Purpose | Institute in charge | Nojima | Soultz |
|---|---|---|---|---|
| Optical +SEM | Fracturing + deformation quantification (offset, volume change) and sequencing | ISTerre Grenoble (Janots, Auzende +M2 Grenoble #1) | Systematic | Done |
| X-Ray CT scan | 3D imaging of attenuation of X-ray in a sample → fracture network + mineral phase distribution | ISTerre Grenoble (Doan) | Selected samples | Selected samples |
