Some new aspects of the geology of Varanger peninsula (Northern Norway). Preliminary report.

Abstract

The authors have established that Varanger Peninsula consists of two different geological regions divided from each other by a large thrus fault trending in NW-SE direction. The south-western, Tanafjord-Varangerfjord region, consists of rocks of the Vestertana Group (Reading, 1965) and of the \"Older Sandstone Series\" (Føyn, 1937). The norht eastern, Barents Sea region, consists of thick sedimentary sequences which are quite dissimilar to the sedimentary sequences present in the Tanafjord-Varangerfjord region. New groups and formations are described in the Barents Sea region, in which the rock assemblages are considered to have been deposited in a mmiogeosyncline. The age of the sedimentary rocks of the Barents Sea region is uncertain; they presumably represent a time period earlier than Cambrian. The Barents Sea region is tentatively regarded as belonging to the Timanian orogenic belt.
