Title: Shallow-Marine Environments in Late Precambrian of Finnmark, Northern Norway: ABSTRACT

Author(s): H. G. Reading

Article Type: Meeting abstract


Processes operating in present shallow seas suggest that shallow-marine clastic sediments are the result of 4 types of current: (1) tidal, (2) waves, (3) semipermanent, and (4) river. Usually one or two current types dominate. However, the effect of each type of current depends on whether it is operating under normal (fair weather) or catastrophic (storm or flood) conditions and the grade of sediment available. The Skalnes Sandstone shows the effect of alternating fair weather and storm conditions on a combination of semipermanent and wave currents. Other parts of the late Precambrian sediments of Finnmark show the dominance of river, tidal, and wave currents.
