A thick succession with lenticular and lenticular-like bedding is described from the basal part of the Seljord quartzites of the Telemark suite. As a result of slumping, concretionary processes, and metamorphism this succession has been modified so that it gives a false impression of being a quartz conglomerate with flattened pebbles. A possible environment of deposition was one of a shallow sea in which tidal currents were active.
