The article provides data on the structure of the Paleoproterozoic intercontinental ImandraVarzuga rifting structure (IVS) and compositions of intrusive formations typical of the early stage of the IVS development and associated mineral resources. IVS is located in the central part of the Kola region. Its length is about 350 km, and its width varies from 10 km at the flanks to 50 km in the central part. IVS contains an association of the sedimentaryvolcanic, intrusive and dyke com plexes. It is a part of a large igneous Paleoproterozoic province of the Fennoscandian Shield spreading for a huge area (about 1 million km 2 ), which probably reflects the settings of the head part of the mantle plume. Two age groups of layered intru sions were associated with the initial stage of the IVS development. The layered intrusions of the FedorovoPansky and Monchegorsk complexes (about 2.50 Ga) are confined to the northern flank and the western closure of IVS, while intrusions of the Imandra complex (about 2.45 Ga) are located at the southern flank of IVS. Intrusions of older complexes are composed of rock series from dunite to gabbro and anorthosites (Monchegorsk complex) and from orthopyroxenite to gabbro and anor thosites (FedorovoPansky complex). Some intrusions of this complexes reveal features of multiphase ones. The younger Imandra complex intrusions (about 2.45 Ga) are stratified from orthopyroxenite to ferrogabbro. Their important feature is comagmatical connection with volcanites. All the intrusive complexes have the boninitelike mantle origin enriched by litho phyle components. Rocks of these two complexеs with different age have specific geochemical characteristics. In the rocks of the Monchegorsk and FedorovoPansky complexes, the accumulation of REE clearly depends on the basicity of the rocks, the spectrum of REE is nonfractionated and 'flat', and the Eu positive anomaly is slightly manifested. In the rocks of the Imandra complex, the level of REE accumulation is relatively higher. The spectrum of REE here differs with more fraction ated LREE with a 'flat' distribution of HREE and distinct Eu anomalies. Rocks of all the intrusive complexes are character ized mostly by negative ε Nd (T) values, and ε Nd values are distributed more heterogeneously in the rocks of the Monchegorsk complex than in the rocks of the FedorovoPansky complex. Deposits and occurrences of Cr, complex PGECuNi and low sulfide PtPd ores of the world class are spatially related and genetically associated with the IVS intrusive complexes. The Sopcheozero deposit (Monchepluton of the Monchegorsk complex) and Bolshaya Varaka deposit (the samename intrusion of the Imandra complex) represent a layered Cr mineralization. Complex PGECuNi deposits are confined to Monchepluton. They occur in vein ores of the NittisKumuzhyaTravyanaya massifs (which have been worked out) and Sopcha, vein PGE Cu, injecting Ni ores mostly and bottom deposits of the NittisKumuzhyaTravyanaya massifs, as well as in the Nyud 'criti cal' horizon.
