The formations include local manifestations of high-magnesium and subalkaline basalt lavas among flood basalts, exotic manifestations of flows of komatiite-like rocks and magnetite lavas and tuff paleovolcanoes, the belt of numerous dykes of varying composition, diatremes with sulfide and magnetite ores, calderas with beds of limestone and anhydrites, as well as manifestations of native copper and bitumen in volcanogenic rocks. The Ti content in traps and its variations in the sequences of layered intrusions depend on the initial composition of a basaltic melt and the extent of its differentiation. Taking into account the vast number of publications on the petrology of Traps of the Noril'sk region, primary attention in the monograph is given to earlier unknown phenomena, as well as other aspects that are of great importance for solving genetic problems. In the geochemistry of nickel, the main attention is drawn to its distribution in rocks and minerals, as well as to behavior of nickel in the process of sulfide formation. Taking into account the vast number of publications on the petrology of Traps of the Noril'sk region, primary attention in the monograph is given to earlier unknown phenomena, as well as other aspects that are of great importance for solving genetic problems.

The leading role in these processes is assigned to three mutually related factors: tectonics, magmatism, and fluid regime of ore—magmatic systems. Formation fluids activated by a melt intruded through the fault zones extracted metals from a basaltic magma, and so became ore-forming fluids. The results of the investigations are presented in two volumes: the first includes mainly text and the second contains illustrations. Taking into account the vast number of publications on the petrology of Traps of the Noril'sk region, primary attention in the monograph is given to earlier unknown phenomena, as well as other aspects that are of great importance for solving genetic problems. Each rock type has been geochemically and petrographically analysed thereby providing a formal identity, complete with a photograph of the thin section.

Photomicrographs of the rocks in this book will be a useful aid in visualizing the diversity of rock types in the Traps; each photograph reflecting a unique combination of minerals. In connection with these matters, a short review of the published experimental data in the field of differentiation and crystallization of silicate and ore liquids, as well as petrogenesis and ore formation that form the basis for genetic models, is given. Some exotic geologic targets such as the Mikchandinsky differentiated cover, the magnetite lava flow of the Putorana Plateau, the magmatogenic breccia of Kharaelakh and others are described in detail. Variations in mineralogy and compositions of principal rock-forming minerals serve as an indicator of basaltic magma differentiation.

Such recurrence is represented by rhythmic alternation of pyroclastic and effusive rocks in the volcanogenic sequence. Features of the composition of olivine, pyroxenes, plagioclase, spinel group minerals, micas, and ilmenite are described in Sect. In the first volume, the state of the main problems of the genesis of igneous rocks with reference to Traps and related ore deposits is discussed, as well as short petrological descriptions of igneous complexes in the region, the mineral and geochemical diversity of the rocks, and aspects of the differentiation of basaltic melts and mineralization are described. It is characterized by a complex geodynamic environment, the most entire sequence of the volcanogenic succession, great variety of hypabyssal intrusions of varying composition, and with different degree of differentiation. Pyroxene is present as augite of the varying composition; pigeonite and orthopyroxene are less abundant. Each rock type has been geochemically and petrographically analysed thereby providing a formal identity, complete with a photograph of the thin section.

The long-continued tectonic activity of deep faults resulted in formation of thick zones of disintegrated rocks. In the first volume, the state of the main problems of the genesis of igneous rocks with reference to Traps and related ore deposits is discussed, as well as short petrological descriptions of igneous complexes in the region, the mineral and geochemical diversity of the rocks, and aspects of the differentiation of basaltic melts and mineralization are described. The second volume contains an atlas of Rock Indications of igneous rock-types; formally identified reference rocks from all igneous complexes of the region, as well as photographs of thin sections of typical rocks and analytical tables of rocks and minerals from the key sections of sedimentary units and intrusions. I was pleased to have this opportunity to review this 2014 English translation as I already had the 2000 Russian version of the set. A great deal of attention is drawn to the problems of Trap magmatism and ore formation.

Formation fluids from sedimentary rocks of the Platform cover were attracted into these zones due to decompression with fluidized zones formed along the faults. The fluid—magmatic interaction of a melt with volatiles facilitated prechamber differentiation of the melt into coexisting immiscible silicate—silicate and ore—silicate melts of variable composition, and crystallization of the melt completed the process of petrogenesis and ore formation. In the first volume, the state of the main problems of the genesis of igneous rocks with reference to Traps and related ore deposits is discussed, as well as short petrological descriptions of igneous complexes in the region, the mineral and geochemical diversity of the rocks, and aspects of the differentiation of basaltic melts and mineralization are described.
