Scientific research exchange programme on the Upper Proterozoic geology of the Varanger Peninsula, Rybachi and Sredni Peninsula, Kildin Island, Bolshoi Aynov and Malyi Aynov Islands. Report from the joint fieldwork on the Norwegian and Russian sides

Abstract

The 1991 fieldwork in this project was a continuation of investigations commenced in 1990. The Norwegian and Russian workers agreed that: (1) The Trollfjorden-Komagelva Fault Zone continues from the Varanger Peninsula to the isthmus between the Sredni and Rybachi Peninsulas; and (2) there is an overall similarity between the Sredni rocks and those of the Tanafjorden - Varangerfjorden Region, and between the Barents Sea Region and the Rybachi rocks. More detailed interpretations of the Norwegian and Russian authors show differences with regard to the lithostratigraphic correlation and the degree of deformation of the rocks southwest and north- east of the fault zone. The studied rocks were sampled for geochemistry, micropaleontology, stroma- tolites, palaeomagnetism and heavy minerals.
