Quaternary foraminifera and sediments in the Norwegian Channel
The foraminiferal fauna and lithology of 17 short sediment cores from two profiles in the Norwegian Channel have been investigated. Three ecostratigraphical zones are distinguished and their depositional environment, age and correlation with adjacent areas are discussed. The zones form a climaticall...

| Summary: | The foraminiferal fauna and lithology of 17 short sediment cores from two profiles in the Norwegian Channel have been investigated. Three ecostratigraphical zones are distinguished and their depositional environment, age and correlation with adjacent areas are discussed. The zones form a climatically conditioned succession (from below): the Cassidulina‐Nonion zone contains an arctic fauna affected by meltwater influx, and its deposition was in progress in Late Weichselian; the Uvigerina‐Cassidulina zone with a mixed fauna of arctic and boreal species is referred to the Early Flandrian; the Uvigerina‐Bulimina zone contains a boreal fauna and was deposited under influence of Atlantic water; its age is regarded as Middle and Late Flandrian. Transport and deposition of sediments in the channel is discussed on the basis of recent current conditions and distribution of the zones. |
