The earliest recognisable folds (F1) in the Seve nappe in the Åre area in the central Swedish Caledonides include a phase of co-axial refolding (F1Aand F1B). These isoclinal, tight reclined or recumbent folds are parallel to the principal mineral lineation and mylonitic striation. There is a set of tight, reclined folds (F2) which refold the mineral lineation and F1hinges at large angles. The open F3folds refold the F2hinges at small angles. In addition to the above structures, there is also a set of open, upright folds (F1) with axes parallel to the mineral lineation (and to F1) which is younger than F1. The time-relation of these F1folds to the F2folds is not clear. The field evidence indicates that F1Band later folds have developed during different stages of thrusting. The period of migmatization and high-grade metamorphism within the nappe has overlapped with the period of development of the F1and F2structures.
