Geological correlation of the Pechenga and Pasvik zones.

Abstract

As the result of an agreement between NGU and A\/S Sulfidmalm, NGU has carried out geological investigations of the Pechenga and Petsamo Group rocks. The main purpose of these investigations was to provide a stratigraphic\/tectonic correlation between the Pechenga Group rocks of the Nickel - Zapolyarny region and the equivalent Petsamo Group of the Pasvik Valley. The result of NGUs field investigations demonstrate that a detailed correlation of all signifi- cant horizons across the border-zone between Russia and Norway can be made. The result of this work also show the need for a number of significant revi- sions of the detailed stratigraphy of the Petsamo Group in both the Pasvik and Polmak areas. The results of NGUs rock geochemical studies are presented in the report. A\/S Sulfidmalm has previously received the analytical data for 220 samples. Recommendations are given concerning the potentially best Ni-Cu prospective areas.
