dc.description.abstract | The Innerelv Member forms part of the succession between the late Precambrian tillites and the Lower Cambrian rocks in eastern Finnmark and it has a considerable lateral extent. It is about 300 m thick in the Tanafjord area but thins to 70 m to the west, at the head of Laksefjord. It can probably be correlated with Member II of the Dividal Group at Halkkavarre 60 km to the southwest (Føyn 1967). Apart from a complex basal zone the Member can be divided into six facies, the first five of which form a gradiation series from mudstones with siltstone laminae through thinly bedded, parallel sided siltstones and very fine sandstones to lenses of intercalated sandstone, siltstone, and mudstone. These five facies represent a series of environments of gradually increasing energy and it is suggested that this energy was related to depth and proximity to a shoreline. The siltstones and sandstones were possibly deposited by currents generated by the backflow of storm surges from an otherwise low energy coastline. | |
