I’d like to call your attention to this book that just came out in four languages, and covers the geology of Fennoscandia (northern Norway and Finland, and the Kola Peninsula).
Another book from the same series is called “Khibiny Tundra – Geological Outdoor Map 1:50000 and Guidebook”.

Finally, there is a map of the Khibiny Tundra.
All three were issued by the Geological Institute of Kola Scientific Center of the Academy of Sciences in cooperation with the Geological Survey of Finland, financed by EU Kolarctic ENPI CBC. Found in the site of the Geological Institute.
