The presence of iron
sulphides is one of the most significant factors affecting roofing slate resistance to weathering and, therefore, the quality of
slates and their use in construction. Iron sulphide oxidation is the main process of roofing slate degradation. Qualitative and
quantitative analyses to determine iron sulphides in roofing slates are usually conducted using transmitted and reflected light
microscopy, and X-ray diffraction techniques. However, this paper presents X-ray computed micro-tomography as a new
laboratory method in this field, which also allows for 3D visualization and analysis of iron sulphide distribution in roofing
slates. It also discusses some technical limits of this technique and tomographic scan interpretation pitfalls. The results obtained
by tomographic observations were subsequently verified by optical microscopy, X-ray powder diffraction and scanning
electron microscopy, as well as energy-dispersive X-ray spectroscopy analyses. Spanish slate from the Ordovician Luarca
Formation and Culm slate from the Moravice Formation in the Czech Republic are both characterized by low to extremely low
iron sulphide content, and for this reason were selected for this study.Pracoviště Ústav geoniky Kontakt Lucie Gurková, lucie.gurkova@ugn.cas.cz, Tel.: 596 979 354 Rok sběru 2019 Elektronická adresa https://qjegh.lyellcollection.org/content/51/2/169
