In this time new geotectonic conceptions, such as plate tectonics, plumе tectonics, deep-geodynamics, were coming to the natural science. At present time science base of tectonics consists of (approximately in equal volumes) preplatetectonic (geosynclinal and other hypothesis) and mobilistic (plate-plumetectonic, geodynamic) notions and terms; its reflects modern geological and geotectonic data about structure and growth of the Earth which are received by learning of oceans basins mainly. Key words: tectonics, geodynamic, notions, terms; megastages, stages and phases of tectogenesis; disciplines, methods and objects of tectonics; tectonic movements and structures; structure-dynamic floors, tectonic (geodynamic) divisions.

Structural-dynamic floors in the Earth’s crust cuts of covered-folded areas are based. It is recommended to allocate them on the basis of: reconstructions of paleostressed fields on the detached areas, which are folded by rocks of different stratigraphic age; identification on this areas vertical zoning of kinematic types of folded and discontinuous structures; isolation of tectonofacieses – classes of intension of the rocks tectonic deformations. Key words: stressed state, dry and water-filled (fluid-filled) rocks massifs; structural-dynamic, kinematic and tectonofacial floors. Р. 29-35 |

The processes are combined into groups (classes): stretching (spreading), compression (approaching), sliding (shifting). The settings are subdividing into types towards lithosphere plates boundaries: divergent, convergent, transform, intraplate. Earlyprecambrian and astrobleme (impact) settings are allocated in separate types. Key words: tectonic (geodynamic) processes (spreading, compression, shifting) and settings (divergent, convergent, transform), accretion, collision, riftogenesis. Р. 35-42 |

(IMGRE, Geokart) // gusev@imgre.ru PREVALENCE OF THE PETROGEOCHEMICAL TYPES AND SERIES OF VOLCANIC ROCKS PREVALENCE AS A CRITERIA FOR RECOGNITION OF TECTONIC (GEODYNAMIC) SETTINGS Prevalence estimates of volcanic rock petrogeochemical types are realized by six parameters: silica, potassium, magnesium, alkalinity, metaluminous, peralkaline or peraluminous series affiliations. These estimates allow us to identify such types of tectonic (geodynamic) settings as non-subduction or subduction ones, continental or oceanic, intraplate or active continental margins, island arcs, back-arc and collision. The signs of the similarities and differences of settings, patterns of evolution and cyclical development of geodynamic structures in connections to their geochemical and mineragenic specialization are elucidated. Key words: volcanics, prevalence, silica, potassium, magnesium, alkalinity, metaluminous, peralkaline, peraluminous, tectonic (geodynamic) settings. Р. 72-76 |

(Geokart) // geokart@hotbox.ru PETROGEOCHEMICAL CRITERIA FOR RECOGNIZING OF TECTONIC (GEODYNAMIC) SETTINGS ON THE COMPOSITION OF VOLCANIC ROCKS Differences of volcanic rocks geochemistry in two groups of tectonic (geodynamic) settings have revealed: non-subduction and subduction-related ones. Subduction-related basic, middle and acidic volcanics differ from non-subduction ones by lower contents of Nb, Ta, La, Ce, Nd, Zr, Hf, Sm, Eu and Ti. Volcanic rocks of mature island arcs, continental margins and collision areas, in contrast to their subduction-related oceanic analogues are enriched in incompatible elements. The concentrations of incompatible trace elements in the volcanics directly correlate with the potassium content in all tectonic (geodynamic) settings. This dependence determines the geodynamic, geochemical and mineragenetic specialization of magmatic rocks. Key words: volcanics, tectonic (geodynamic) settings, incompatible, geochemical spectra, specialization, minerageny. Р. 76-81 |
