The Lower Ludlovian Colonus Shale of Scania contains instances of probably late Paleozoic folding tending to overthrusting, with axes mainly in NW—SE directions. There may have been several episodes of deformation, of which at least one is probably older than (Borcovician) dolerite dykes. A temporarily exposed section at Skillinge, SE Scania, displays a strong folding as well as sediment structures like groove-casts, flute-casts and load-casts indicating (along with similar structures at other outcrops) sediment transport from W—NW toward E—SE in late Silurian times.
