Nano‐Scale Characterization of Particulate Iron Pyrite Morphology in Shale

This study analyzes the morphology of iron pyrite particles within a shale sample captured using nano-computed tomography (Nano-CT). The complex, framboidal is characterized various metrics, and comparisons are drawn on their effectiveness to quantify observed morphological characteristics. Then, simplified representations selected generated facilitate sensitivity analysis effect imaging resolution parameters particle form. A discussion developed required number pixels per diameter for shape characterization. It shown that indices rely main dimensions can be accurately calculated even low fidelity levels 10 diameter. More complex use vertices, volume, surface area, more sensitive image resolution, 40
