Minor tectonic structures affecting Downtonian Old Red Sandstone sediments on Hitra indclude folds parasitic to a major syncline, and an associated axial surface spaced cleavage. The cleavage is most prominent in mudstones, and appears to represent dissolution foliae; no neocrystallization has been detected. In these rocks carbonate nodular concretions show evidence of mechanical rotation from bedding-parallelism towards the plane of the cleavage. Younger structures are represented by crenulations and kink bands.
