Info

The Kola Peninsula is a mining area extremely rich in apatite, copper, nickel and cobalt, iron, rare metals, and micas, as well as in high-alumina ceramic and abrasive materials, and facing and decorative stones. Over 800 samples of different ores and minerals from these deposits are exhibited in the Museum. The petrography collection of igneous, metamorphic and sedimentary rocks from different massifs of the Kola Peninsula has over 900 samples. Over 130 new minerals of 210 first found on the Kola Peninsula, including 56 minerals discovered by the researchers of the Geological Institute, are to be admired in the exposition hall of the museum. 14
Day 2 Trip to the Lovozero Mountains area. Start from Apatity at 8.00. Finish in Kandalaksha at 20.00. Total distance of transportation is 390 km. Maximum easy hiking at stops no more than 750 m.

Excursion 1: Glacial landforms of N-W Lovozero Mountains Lovozero massif is one of the two major nepheline syenite plutons situated in the central part of the Kola Peninsula and stand today as elevated plateau with steep precipitous slopes and flat summits. The summit surfaces (1000-1119 m a.s.l. in the western part and 600-974 m a.s.l. in the eastern one) are elevated almost a kilometer above the surrounding hilly plain because of the active tectonic uplift. They probably are the Mesozoic past-peneplain. The Lovozero massif occupies a territory of 25x25 km between two Lakes Umbozero and Lovozero with Lake Seydozero nestling in the centre. The western contact is only 5 km away of the Khibiny. Whole rock and mineral Rb-Sr isochrons gave the ages of 370.4 ± 6.7 Ma for the main stage of igneous activity (Kramm and Kogarko, 1994). The massif intruded into the garnet-biotite gneisses of the Archean age. The zone of fenitized rocks extends for 50-200 m. Fenites are represented by eudialite-microcline and amphiboleoligoclase varieties. Numerous nepheline syenite veins and alkaline pegmatites penetrated the country rocks at the distance of more than 100 m from the contact. The Lovozero intrusive complex has the form of a laccolith with a broad base. Due to subhorizontal position of layers in the differentiated complex, the geological map of Lovozero appears as a topographic plan of the area, and the key layers follow the contour lines of the 15
