Utilization of X-ray computed micro-tomography to evaluate iron sulphide distribution in roofing slates

Original language description

Slate is a traditional stone product that has long been used for roofing widely around the world. The presence of ironnsulphides is one of the most significant factors affecting roofing slate resistance to weathering and, therefore, the quality ofnslates and their use in construction. Iron sulphide oxidation is the main process of roofing slate degradation. Qualitative andnquantitative analyses to determine iron sulphides in roofing slates are usually conducted using transmitted and reflected lightnmicroscopy, and X-ray diffraction techniques. However, this paper presents X-ray computed micro-tomography as a newnlaboratory method in this field, which also allows for 3D visualization and analysis of iron sulphide distribution in roofingnslates. It also discusses some technical limits of this technique and tomographic scan interpretation pitfalls. The results obtainednby tomographic observations were subsequently verified by optical microscopy, X-ray powder diffraction and scanningnelectron microscopy, as well as energy-dispersive X-ray spectroscopy analyses. Spanish slate from the Ordovician LuarcanFormation and Culm slate from the Moravice Formation in the Czech Republic are both characterized by low to extremely lowniron sulphide content, and for this reason were selected for this study.
