Neoproterozoic sedimentary rock successions of the Barents and White Sea Coasts of the Kola Peninsula, Northwest Russia.

Abstract

(Forkortet) The Neoproterozoic sedimentary rock successions occurring along parts of the northern and southern coasts of the Kola Peninsula in NW Russia were, for a long time, poorly known to western geoscientists. In this report, detailed descriptions are given of the various groups and formations that constitute the lithostratigraphical successions in the different areas, based on the results of joint Russian-Norwegian project work in the early 1990s and also on earlier Russian mapping and geochemical sampling programmes. The information provided on these successions, their microfossil assemblages, and on their subsequent Baikalian deformation and very low-grade metamorphism, is clearly of great value to geologists working on comparable Neoproterozoic successions in eastern Finnmark.
