The Arctic region is aprospective areafor ore mining and urbanization progress. The areas of Europe located beyond the Arctic Circle have unique features of the natural environment. Conducting mining works in this place is associated with certain difficulties resulting from weather conditions (numerousrains, long winters, polar night) anddue to the high riskof permanent environmental pollution. An example of the specificity of arctic mining is Kvalsund in northern Norway, where there is a copper mine that is currently under development. Another example is the Monchegorsk region in Russia, which is currently no longer mining. Both of these places are associated with sulphide deposits of non-ferrous metals and the resulting consequences. The purpose of this text was to show the differences and similarities of these mining plants, andon this basis to demonstrate the complexity of the issues of exploitation and reclamation of mining areas in the Arctic.

Interesting landscape forms associated with glacial activity occur in the Alta region, in Northern Norway. They attract tourists who want to visit Nordcapp - the northernmost place in Europe that can be reached by car. This area is located within the Scandinavian Mountains, which form a series of nappes containing metamorphosed rock complexes with numerous intrusions. The Alta-Kvænangen and Repparfjord tectonic windows with outcrops of Proterozoic and Archaic rocks occur there. The analysed formations, in the vicinity of Alta, are associated with more than two billion years of history of the development of the geology of this area. They are the basis of numerous geomorphological forms and can complement tourist attractions. This article is devoted to the discussion of the rocks forming the tectonic windows in the Alta, Kvalsund region, and the metamorphic formations of the Hammerfest region, a complex of igneous rocks of Mager ay Island, as well.

A petrographic description of olivine, ortho-, clinopyroxene, and plagioclase was obtained for rocks derived from a Paleoproterozoic layered intrusion of the Monchepluton. Based on these results, calculations were made of the fractal box dimension, which determines the degree of development of the boundaries of these minerals. After the calculations, they were illustrated on maps showing the correlation of this coefficient with the location of the sample in the field. These results were then correlated with petrographic observations. Based on this method, the analogies between the result of the fractal dimension and the petrographic description of rock-forming minerals were assessed. The data show that such an analogy to a limited extent may be a significant indicator for the interpretation of the results. The use of this method is not universal and strictly depends on the mineral association and the knowledge obtained by classic petrographic studies.
