The present paper considers the research of the Cretaceous-Cenozoic rifting for the Eastern margin of Asia occurring under the strike-slip related geodynamic regime, which resulted from development of the Eastern Asian global strike-slip fault zone (EAGSSFZ). The EAGSSFZ infrastructure proves to be recognized. It includes the longitudinal system of the NE (25-30°) trending sinistral faults, which form the through strike-slip fault zone to be pivot for the EAGSSFZ, together with two diagonal systems: the NE (50-70°) trending near-continental system of obligue-reverse-slip faults and the N-S trending near-oceanic fault system, which are feathering for the pivot zone. The paragenesis of the longitudinal and diagonal near-continental systems is studied. There are two paragenetic stages of their development: 1) the Jurassic-to-Early-Cretaceous orogenic stage is to be an effect of the formation of the diagonal system of the fold-thrust dislocations as compression structures of the longitudinal sinistral fault system (orogenic strike-slip related constriction of masses continued through the end of Early Cretaceous); 2) the Late-Cretaceous-to-Cenozoic riftogenic stage is to be an effect of riftogenic extension (pulling apart) of the crustal block bounded by the sinistral faults of the longitudinal system and due to the rifting that was caused by substitution (within the diagonal system) of predominantly reverse-and-thrust fault kinematics (of the 1st stage) for sinistral slips with development of the riftogenic extension structures controlling sedimentary basins along the strike-slip faults. At the same time, the sinistral activation of the diagonal fault system comprising the Bohai-Amur (BA) zone caused transformation of the Tan-Lu (TL) strike-slip fault into the extension structure, forming here the up-to-80-km-wide riftogenic trough with subsidence of its sides that led to formation of the North Chinese sedimentary basin up-to-700-km-wide. Being identical with the TL rift by orientation, morphology, and depth of initiation, the Eastern Amur rift formed also synchronously with the TL rift that corroborates opening of the latter via south-westward displacements of the NW sides of the BA system’s strike-slip faults. The established sinistral displacements of the NW sides for the faults belonging to both the diagonal and longitudinal systems to the south-westward (the total displacements’ sector is SW 205-250°) show dynamo-kinematic activity of the Asian continent in the processes of rifting of the Eastern margin of Asia.

The research on petrochemistry and geochemistry of rare, rare earth and platinum group elements in the rocks Shaman massif - the largest ultramafic protrusion body in eastern branch of the Baikal-Muya ophiolite belt, performed using a different of analytical techniques (X-ray fluorescence analysis, mass spectrometry analysis with inductively coupled plasma and laser ablation; synchrotron radiation method). Harzburgites and subordinate dunites, composing massif, depleted TiO₂, Na₂O, K₂O and CaO, and rare earth elements (REE). The total content of the latter in harzburgites somewhat higher (0.29-3.01 ppm) than in dunites (0.12-1.54 ppm). The patterns of chondrite-normalized REE contents in ultramafic rocks are arched downward configuration, due to their abnormal enrichment nonstructural admixture of light elements, centered as it is assumed in the intergranular and within granular microcracks. Massif is characterized by higher contents of Zr and Hf, the hub of which is supposed to be an accessory zircon. The total content of platinum group elements (PGE) in the harzburgite and dunite are from 12.50 to 24.35 ppb, while the predominant element is Ru. There was an inverse relationship between its content and the content of heavy rare earth elements (Er, Tm, Yb, Lu), and between the total content of PGE and REE, which are supposed to be due to divers directional fractionation of these groups of elements with contrasting properties in the process of partial melting of upper mantle protolithe. Prevalence of Ru in the rocks suggested that PGE concentrated mainly in the such minerals as rutenosmirid and laurite.

Case study of the differentiated subvolcanic porphyritic intrusion underlying Magnitogorsk skarn-magnetite deposit revealed regular relations between petrochemistry features of the rocks and composition of halogens (Cl and F) in the accessory apatite. During the process of intrusion formation in terms of general trend of differentiation from the pyroxene-porphyrites its base to atachites (trachyandesites, phonotephrites) its upper part, several autonomous fluid-magmatic systems (FMS), which differ in major and trace elements distribution as well as halogen composition in apatites, are formed. In the uppermost part of the atachite section, mostly saturated by alkalis and volatile components, through a further fluid-magmatic stratification were formed two atachite strata: sodium, enriched in Na, Ca, Sr, and with a higher Cl content in apatite and potassium “ore-bearing” located at a higher hypsometric level and enriched in K, Rb, Fe, V, Ti, P, with a higher content of F in apatite. Formation of subvolcanic intrusion was accompanied by repeated occurrences of explosive phenomena. These data indicate the features of magmatism in Magnitogorsk megazone in D₃-C₁, at the change the island-arc stage by accretionary-collision (island arc-continent) one

Accorting to examination of the small structural forms and rotation shapes a new geotectonic model of the Karabash massif’ formation which is located in a zone of the Main Uralian Fault is considered. The clockwise torsion, steep incline axis to the North-East, cracking and several other features are explained by the conditions of tectonic crustal-mantle flow’s rising in a regional zone of a right shift. Eastern block was active. Conditions of decompression and warm-up caused avtometamorfizm and antigoritisation of ultrabasite. A rapid pressure collapse in the upper horizons of a crust was accompanied by a formation of the large steep echelon-like stretching cracks sub-parallel the sides of a shear zone in which metamorphic fluids were thrown off. As a result of sintectonic hydrothermal mineralization the stretching cracks filled by diopside, chlorite, garnet, carbonates and other minerals which formed the rodingite-like metasomatic rocks. Early rodingites were also subjected to deformation in a right shift zone (cataclasis, boudinage, rotational deformation) with simultaneous filling of cracks by the new generations of above-mentioned minerals. As a result of this deformations in the rodingite veins were formed the especially intensive cataclasis pillar-like zones. These zones have a steep fall to the NE and contain the richest gold ore. Following an interpretation of a satellite imagery there are three gently dipping (about 35°NE) of tectonic fractures cutting of the Karabash massif are distinguished. It is suggested that these fractures are the large torsion cracks which cut the the southern flank of a field. With a taking in a mind of rotation direction a lower part of the southern flank of a gold deposit could be located further to the east.

The formation of Verkhne-Aliinsky gold deposit is associated with formation of annular volcano-plutonic structure (VPS), which central parts consists of granite-porphyries Shakhtamin complex (J_2-3) and peripheral parts constracts by effusive rocks of Shadaron series (J_2-3). High-temperature ore mineral associations developed in the central part of VPS, and low-temperature - in the peripheral part. Petrochemical data of rocks from VPS indicates to their forming in consequence of crystallization differentiate from the mantle source. The formation of ore-bearing fluid took place owing to processes of mantle-crustal interaction.

The halogen deposits opened with the wells drilled in the Nivensk hollow of Kaliningrad-Gdansk saliferous pool are studied. The executed researches confirm significantly sulfate-chloride type of a brine in the pool of sedimentation and an important role of calcium and sulfate-ion in processes of replacement of potassium minerals at a postsedimentation stage of their transformation.

The provision of early mesozoic grabens (rifts) filled with terrigenous deposits and basalts of the Triassic in tectonic volume model of crystal crust is considered. Taking into account the similar analysis on the Upper Paleozoic granitization and arrangement of fields of hydrocarbons, which were made earlier, the causation of tectonics and magmatism with a deep structure of upper part of a lithosphere of Uural area of the West Siberian geosyneclise is emphasized. The common source of these phenomena caused by joint activity of a deep underearth in a Upper Permian-Triassic stage of development of the studied geological environment is offered.

Mineralogy of granitic pegmatites of Mt. Soroch′ya near Zlatoust which ore included in the Upper Riphean metamorphic mica-garnet, staurolite-garnet, and wollastonite-sillimanite-garnet schists of the Kuvash Formation is examined. Zonal pegmatite veins 30-600 m long and 1-40 m thick are composed of (from margin to centre): 1) pegmatoic quartz-two-feldspar with muscovite and biotite; 2) graphic muscovite-quartz-two-feldspar; 3) blocky with large crystals of microcline, muscovite (up to 10 cm) and quartz in small-grained quartz-albite aggregate; and 4) quartz core zones. The composition of formerly known mica, tourmaline, zircon, rutile and first time discovered xenotime-(Y), monazite-(Ce), Ta-bearing rutile (“strьverite”), and gold is ore described.

There are complex of data about composition, age, isotopic parameters for granites from the Ufaley block, which is situated in the accretion zone on the boundary between the Urals and the East European platform. Granitoides mark the main stage of the geological structure evolution: from the intraplate rifting (episodes 1100-880, 570-533, 476-457 Ma) with full and partial rupture of the crust to the beginninf of orogenes (about 317 Ma) and collision (260-250 Ma). On the base of isotopic data we show that there is the substantial evolution of the source in time reflecting the increasing of part of sialic component in the source for granite formation. Maximal quantity of the granite impulses was fixed within the Ufaley block and it’s neighboring marginal structure - Bashkirian anticlinorium. This fact notes to involvement here the margin of East European platform to all episodes of tectonic-magmatic activity from the Riphean rifting to Paleozoic orogenesis which was maximal during the formation the own Uralian collision orogen.
