In Devonian carbonates of the Holy Cross Mountains (HCM) are documented the record of three individual episodes of remagnetisation. The fold test performed within map-scale folds from central part of the HCM documented early synfolding origin of the Viséan component and postfolding nature of the Early Permian and Permo/Triassic overprints. The results confirmed that the westernmost parts of the HCM were rotated clockwise after the Early Permian. Paleomagnetic studies of this zone documented shape modifications in part of the large map-scale folds as well as some of smaller meso-scale folds. Such a tectonic overprint occurred after the Early Permian, most probably in the course of Late Variscan deformations. Further results indicate that the studied N-S trending dextral strike-slip faults were active between the Early Permian and the Permo/Triassic period. Overlying breccia that covers discordantly deformed Devonian strata was formed after the Early Permian.
