Abstract

Stratigraphic sections and key localities were examined on both sides of the national border during this first season of the international collaboration. During fieldwork on Varanger Peninsula the Russian workers concentrated on conglomerates, diagenetic concretions and palaeoclimatic indicators as tools useful for correlation. The Norwegian participants examined sections mainly on Rybachi, Sredni and Kildin Island in terms of sedimentary facies interpretation and studies tectonic deformation and low-grade metamorphism. They concluded thatthere is a good evidence for an extension of the Trollfjorden - Komagelva fault Zone from the Varanger Peninsula towards the isthmus between the Sredni and Rybachi Peninsulas. Alternative preliminary lithostratigraphic correlations were proposed by the Norwegian and the Russian authors.
