“…Similar results were also observed in the isotopic studies of sulfides taken from drilling and surface sampling troctolites and gabbro and contact zones of the central massif Fiodoro-Pana Tundra. They showed serious evidence multi-sulfide and oxide mineralization stages in establishing the changes in the isotopic distribution of the alloy from which the crystallization was emerged (Huber et al, 2009).…”

Abstract:The sulfide minerals from old mafic intrusion rocks from the Kola Peninsula were analyzed on stable sulfur isotopes. These samples were already dated by the Sm-Nd method. These sulfide samples were evaluated upon a geochemical composition by ICP-MS. The sulfide mineral samples were selected from the main ore-bearing rocks of the Monchetundra layered intrusion. The analyzed sulfides formed several generations of mineralization associated with primary and hydrothermal stage of formation of the deposits. Isotopic studies confirm a few consecutive stages of mineralization. These data were compared with the results of Sm-Nd dating of sulfide mineralization. The results of geochemical and geochronological studies indicate a complementarity in the context of determining the mineralization stages.

“…These rocks metamorphosed in the amphibolite and granulite facies [18,19]. Alkaline metavolcanic rocks and granitoid intrusions occur in the vicinity of the discussed pegmatite sites [20][21][22]. This is the case in the Kaustinen and Kolmozero areas, where numerous pegmatite veins can be found in these rocks [23][24][25][26].…”

Li-Ce-Ta (LCT) pegmatites containing lithium mineralization in the form of spodumene and lepidolite, as well as fuchsite, from the regions of northern Scandinavia (N Norway, N Finland, N Russia) were studied. Detailed analyses of the chemical compositions of these minerals were carried out, involving scanning electron microscopy (SEM) with energy-dispersive spectroscopy (EDS), Fourier transform infrared (FTIR) spectroscopy with attenuated total reflectance (ATR), and X-ray photoelectron spectroscopy (XPS) studies. Their crystal structures were confirmed with the X-ray diffraction technique. Studies involving microscopy were also carried out, indicating the optical features of these minerals. Based on the analyses carried out in the studied rocks, the characteristics of these minerals were determined, as well as the crystallization conditions. This research indicates that the N Scandinavian area is prospective and may lead to further discoveries of this type of pegmatite in the studied region.

“…In the blocks belonging to the NKT, there are rocks of dunite and harzburgite, and clinopyroxenite rocks containing chromites (Figure 4A) and olivine-pyroxene bodies (Figure 4B). In the area of Sopcha, Nyud, and Poaz, there are orthopyroxenites, olivine norites and gabbronorites-also with numerous interesting zones showing the rhythm of the formation of intrusion [37,[50][51][52][53]. In the Hippik area, the gabbro is exposed [37,38].…”

Monchegorsk is an intrusion complex of basic and ultrabasic rocks of the Paleoproterozoic age. This complex formed during active magmatic mobility that took place in NE Scandinavia 2.5 Ga years ago. These were the subject of intensive exploration and exploitation at the beginning of the 20th century, the latter carrying on through to the beginning of the 21st century. This contributed to the creation of some different forms of post-industrail mining infrastructure in the area. Many mining settlements, including Monchegorsk, mining plants, adits and quarries were established during this time, the relics of which are still present today. The Monchegorsk intrusions complex is formed by several fragmented massifs: Traviannaya, Kumuzhia, Nittis, Sopcha, Nyud, Poaz, and Monchetundra, the highest elevations of which reach up to 1000 m above sea level. These massifs form a landscape of “islands” and mountain ranges that have influence upon the regional landscape over several tens of kilometers. Their geography is characterized by numerous reliefs, glacial cirques, rocky thresholds with waterfalls and trough lakes. The potential of this region lies in the heritage of historical exploitation, numerous monuments of which have been preserved to this day. An important value is a landscape resulting from the relief of these mountains, highlighted by glacial activity in the Pleistocene. There are also interesting examples of Arctic fauna and flora, and of the rocks that form the bedrock in this intrusion. Some of the mineralization of these outcroppings can also be admired in the collections of the local museum that serves as a geocenter. The possibility of admiring relatively easily accessible views (the international route St. Petersburg–Murmansk–Kirkenes passes through the middle of the hills) and the interesting geology of the area abounding in rocks of mineralogical significance, their exposures, and history, along with the possibility of observing various post-industrail forms, make this area of great tourist potential. This article describes the most interesting exposures of outstanding tourist value and proposes routes connecting these points. It also discusses the problem of securing these exposures and the necessary tourist infrastructure, which is currently lacking.
