Abstract

The Imandra/Varzuga Greenstone Belt (Figs. 4.1 and 4.2) has been the target for continuous exploration for Pt, Ni, Cu, and Au, which has allowed to establish a regional geological framework including information on the stratigraphy, regional geochemistry, metamorphic zoning, and igneous petrology. Main regional geological features were established during the 1:200,000 scale mapping in the 1960s (Potrubovich and Simon 1966) and subsequently complemented by academic research (Kharitonov 1966; Kozlov 1971; Gilyarova 1972; Radchenko 1972a; Bekasova and Pushkin 1972). Later results of the 1:50,000 scale mapping were combined with considerable contributions from various research programmes, as summarised in four monographs devoted to the general geology and stratigraphy (Zagorodny et al. 1982), sedimentology (Melezhik and Predovsky 1982), and geochemistry of sedimentary and volcanic rocks of the Imandra-Varzuga Belt (Fedotov 1985; Predovsky et al. 1987; Borisov 1990). Geotectonic and geodynamical aspects have been addressed in several papers by Zagorodny and Radchenko (1988), Mints (1993), Melezhik and Sturt (1994), and Mintz et al. (1996). There is only a limited number of geochronological measurements constraining the depositional time of sedimentary and volcanic rocks (Amelin et al. 1995; Skuf’in et al. 2006; Vrevsky et al. 2010), though a considerable effort has been focussed on dating the emplacement of economically important layered gabbronorite complexes (Bayanova et al. 2009).
