    The Olkhon region of the Western Pribaikalie is highly attractive for geologists due to the presence of diverse metamorphic complexes and highly complicated combinations of folded structures in this region. The Olkhon region is located within the area of the Pribaikalsky National Park of Russia. At abundant outcrops in the subject area, various geological aspects resulting from the Early Palaeozoic collision system can be studied in detail. By its parameters, the subject area can be considered a Β«geodynamic proving groundΒ». In recent years, abundant aerospace materials on the area have been accumulated, and long-term field studies resulted in many discoveries and findings which encourage critical revision of the initial conceptions. The material available allows compilation of a new package of geological maps in hard and electronic versions.ΠžΠ»ΡŒΡ…ΠΎΠ½ΡΠΊΠΈΠΉ Ρ€Π΅Π³ΠΈΠΎΠ½ Π² Π—Π°ΠΏΠ°Π΄Π½ΠΎΠΌ ΠŸΡ€ΠΈΠ±Π°ΠΉΠΊΠ°Π»ΡŒΠ΅ Π΄Π°Π²Π½ΠΎ ΠΏΡ€ΠΈΠ²Π»Π΅ΠΊΠ°Π΅Ρ‚ Π²Π½ΠΈΠΌΠ°Π½ΠΈΠ΅ Π³Π΅ΠΎΠ»ΠΎΠ³ΠΎΠ² Ρ€Π°Π·Π½ΠΎΠΎΠ±Ρ€Π°Π·ΠΈΠ΅ΠΌ мСтаморфичСских комплСксов, слоТнСйшими комбинациями складчатых структур.

    The Early Paleozoic collisional system located in the Olkhon region at the western shores of Lake Baikal resulted from collision of the Siberian paleocontinent and a complex aggregate composed by fragments of a microcontinent, island arcs, back-arc structures and accretionary prisms. The main events were associated with complete manifestation of shear tectogenesis initiated by oblique collision. The current structure includes tectonically displaced components of ancient geodynamic systems that used to have been located dozens and hundreds of kilometres apart. Horizontal amplitudes of tectonic displacement seem to have been quite high; however, numerical data are still lacking to support this conclusion. Information about the structure of the upper crust in the Paleozoic is also lacking as only deep metamorphic rocks (varying from epidote-amphibolite to granulite facies) are currently outcropped. Formations comprising the collisional collage are significantly different in composition and protoliths, and combinations of numerous shifted beds give evidence of a 'bulldozer' effect caused by the collisional shock followed by movements of crushed components of the ocean-continent zone along the margin of the Siberian paleocontinent. As evidenced by the recent cross-section, deep horizons of the Early Paleozoic crust comprise the collisional system between the Siberian craton and the Olkhon composite terrain.Β A permanent inclusion in the collisional combinations of rocks are unusual synmetamorphic injected bodies of carbonate rocks. Such rocks comprise two groups, marble melanges and crustal carbonate melted rocks. Obviously, carbonate rocks (that composed the original layers and horizons of stratified beds) can become less viscous to a certain degree at some locations during the process of oblique collision and acquire unusual properties and can thus intrude into the surrounding rocks of silicate composition. Such carbonate rocks behave as protrusions or intrusions and contain inclusions of silicate rocks. Formation of marble melanges is a multi-staged process: they occur as early tectonic covers and, more often, accompany shear zones of large lengths, comprise late push-out nappes initiated by shear faults, participate in construction of ring and vortex structures that are generated by shearing in the geological medium of inhomogeneous rheology. In general, the available data give evidence of the fact that formation of synmetamorphic marble melanges is a direct consequence of the oblique collision geodynamics and a sensitive indicator of such a regime. A pure guesswork may suggest that the occurrence of the marble melanges can be associated with a catastrophic loss of viscosity of the carbonate rocks due to a sharp increase of velocities of shear deformations that accompanied the oblique collision. РаннСпалСозойская коллизионная систСма ΠžΠ»ΡŒΡ…ΠΎΠ½ΡΠΊΠΎΠ³ΠΎ Ρ€Π΅Π³ΠΈΠΎΠ½Π° (Π·Π°ΠΏΠ°Π΄Π½ΠΎΠ΅ ΠΏΠΎΠ±Π΅Ρ€Π΅ΠΆΡŒΠ΅ Π‘Π°ΠΉΠΊΠ°Π»Π°) Π²ΠΎΠ·Π½ΠΈΠΊΠ»Π° Π² процСссС столкновСния Бибирского ΠΏΠ°Π»Π΅ΠΎΠΊΠΎΠ½Ρ‚ΠΈΠ½Π΅Π½Ρ‚Π° ΠΈ слоТного Π°Π³Ρ€Π΅Π³Π°Ρ‚Π° ΠΈΠ· Ρ„Ρ€Π°Π³ΠΌΠ΅Π½Ρ‚ΠΎΠ² ΠΌΠΈΠΊΡ€ΠΎΠΊΠΎΠ½Ρ‚ΠΈΠ½Π΅Π½Ρ‚Π°, островных Π΄ΡƒΠ³, Π·Π°Π΄ΡƒΠ³ΠΎΠ²Ρ‹Ρ… структур, Π°ΠΊΠΊΡ€Π΅Ρ†ΠΈΠΎΠ½Π½Ρ‹Ρ… ΠΏΡ€ΠΈΠ·ΠΌ.

    Objective: to define a role of various maintenance modes, such as enteral tube feeding (ETF) and complete parenteral feeding in different phases of acute pancreatitis (AP). Subjects and materials. The impact of various modes of nutritional support on pancreatic secretory activity and the course of AP was comparatively analyzed in 774 patients (mean age 45.3Β±4.7 years) with AP. The criteria for evaluation of the activities of the pancreas and its inflammatory process activity were considered to be clinical and laboratory parameters (pain, body temperature, hemogram, amylasemia, the degree of dynamic ileus and abdominal inflammatory infiltrate, and the level of gastrointestinal peptides), and ultrasonographic and computed tomographic data. The additional impact of different types of protein-calorie provision on pancreatic secretory activity was studied in 23 patients with external pancreatic fistulas, by using debetometry. Results. ETF was shown to have a stimulating effect on pancreatic secretion and AP worsening when it was used in the early phases of the disease. The optimum time of complete parenteral feeding (days 5β€”14 after the onset of the disease) and the criteria for the possible initiation of ETF were determined. Emphasis was laid on the important role of enteral feeding in a package of therapeutic measures in AP in the phase of pyonecrotic lesions. Conclusion. The proposed nutritional support tactics along with mini-invasive surgical treatments could reduce postoperative and overall mortality rates to 4.2 and 3.7%, respectively. Key words: acute pancreatitis, protein-calorie provision, nutritional support, enteral tube feeding, parenteral feeding, intestinal lavage, pancreatic secretion.ЦСль исслСдования .

    Metamorphic core complexes (hereafter MCC) revealed in the Transbaikalia have similar features of their patterns. Three levels can be distinguished by structuralΒ­material indicators: core, zone of mylonites (dynamically metamorphosed rocks) and overlying formations. The cores are composed of the Paleozoic granites and granitogneisses. Zones of mylonites skirt the cores and are characterized by various tectonites which are formed at the expense of the core rocks. The overlying formations include volcanogenicΒ­sedimentary series of the Mesozoic and the Upper Palaeozoic. The rocks are not metamorphosed, yet subject to brittle deformations. Structurally, they are detached and deposited above the zone of mylonites.In Transbaikalia, MCC are characterized by synmetamorphic structural paragenesises of one type: lowΒ­angle schistosity, microΒ­Β and macroΒ­structures (folds, mineral streaking, boudinage, pressure shadows, C–S structure, kickΒ­bends). According to the kinematic analyses, they were formed by the simple shear mechanism along the zones of deeply penetrating regional dislocations which plunged in the southΒ­eastward direction. Tectonic transportation of the materials developed in the same direction, i.e. the top parts of tectonoΒ­stratigraphic sections were displaced against the lower parts in the southΒ­eastward direction. Extension deformations tended in the northΒ­west – southΒ­east direction. Such movements facilitated formation of synthetic listric normal faults and rift basins. The most intensive tectonic exposure period is determined as 112–123 mln years, while the period of metamorphism is assessed as 140–130 mln years. The rocks in depth of the deep dislocation were transformed in conditions of amphibole facies of metamorphism (Π’=590–640 Β°Π‘ΝΎΒ Π =3.2–4.6 kbar).According to our structural-Β­geological, petrological and isotopic data, the age of the majority of the metamorphic formations of the Transbaikalia is determined as the Late Mesozoic. They were formed in the extension regime due collapse of the Late Mesozoic orogeny, that was caused by accretionΒ­collision events during the Early Mesozoic. Thickening of the continental crust contributed to increase of heat flow and higher plasticity at the crustal bottom. The orogen was thus unstable and flowing and caused regional extension and dislocations at the middleΒ­crust level. Thinning of the crust was accompanied by isostatic uplifting which facilitated emergence of the structural metamorphic complexes of the middleΒ­crust levels on the surface and formation of the metamorphic core complexes.УстановлСнныС Π² Π—Π°Π±Π°ΠΉΠΊΠ°Π»ΡŒΠ΅ комплСксы мСтаморфичСских ядСр (metamorphic core complexes – МББ) Ρ…Π°Ρ€Π°ΠΊΡ‚Π΅Ρ€ΠΈΠ·ΡƒΡŽΡ‚ΡΡ Π±Π»ΠΈΠ·ΠΊΠΈΠΌΠΈ Ρ‡Π΅Ρ€Ρ‚Π°ΠΌΠΈ строСния.

    We announce the second edition of the Aerospace geological map of the Olkhon Region (Baikal, Russia), scale 1:40 000, which was published in 2017. The map has been considerably revised and updated, and its changes are critical for correct understanding of the regional geology, tectonics and geodynamics. Only a small number of its printed copies have been released, and therefore the map may not be available for all interested specialists. The electronic version of the map is available for studying and/or printing (see the link to its pdf file in the paper’s supplement). The pdf file is about 68 MB, i.e. small compared to the original map (more than 5 GB), but the quality is maintained. The map does not show the base layer due to the terms of the licenses owned by the companies and satellite owners.НастоящСС ΠΊΡ€Π°Ρ‚ΠΊΠΎΠ΅ сообщСниС являСтся Π² Π·Π½Π°Ρ‡ΠΈΡ‚Π΅Π»ΡŒΠ½ΠΎΠΉ стСпСни анонсом Π²Ρ‚ΠΎΡ€ΠΎΠ³ΠΎ издания АэрокосмичСской гСологичСской ΠΊΠ°Ρ€Ρ‚Ρ‹ ΠžΠ»ΡŒΡ…ΠΎΠ½ΡΠΊΠΎΠ³ΠΎ Ρ€Π΅Π³ΠΈΠΎΠ½Π° (Π‘Π°ΠΉΠΊΠ°Π», Россия) ΠΌ-Π±Π° 1:40000, ΠΈΠ·Π΄Π°Π½Π½ΠΎΠΉ Π² 2017 Π³.

    THE OLKHON GEODYNAMIC PROVING GROUND (LAKE BAIKAL): HIGH RESOLUTION SATELLITE DATA AND GEOLOGICAL MAPS OF NEW GENERATION

    No full text
    The Olkhon region of the Western Pribaikalie is highly attractive for geologists due to the presence of diverse metamorphic complexes and highly complicated combinations of folded structures in this region. The Olkhon region is located within the area of the Pribaikalsky National Park of Russia. At abundant outcrops in the subject area, various geological aspects resulting from the Early Palaeozoic collision system can be studied in detail. By its parameters, the subject area can be considered a Β«geodynamic proving groundΒ». In recent years, abundant aerospace materials on the area have been accumulated, and long-term field studies resulted in many discoveries and findings which encourage critical revision of the initial conceptions. The material available allows compilation of a new package of geological maps in hard and electronic versions

    TECTONIC POSITION OF MARBLE MELANGES IN THE EARLY PALEOZOIC ACCRETION-COLLISIONAL SYSTEM OF THE WESTERN PRIBAIKALIE

    No full text
    The Early Paleozoic collisional system located in the Olkhon region at the western shores of Lake Baikal resulted from collision of the Siberian paleocontinent and a complex aggregate composed by fragments of a microcontinent, island arcs, back-arc structures and accretionary prisms. The main events were associated with complete manifestation of shear tectogenesis initiated by oblique collision. The current structure includes tectonically displaced components of ancient geodynamic systems that used to have been located dozens and hundreds of kilometres apart. Horizontal amplitudes of tectonic displacement seem to have been quite high; however, numerical data are still lacking to support this conclusion. Information about the structure of the upper crust in the Paleozoic is also lacking as only deep metamorphic rocks (varying from epidote-amphibolite to granulite facies) are currently outcropped. Formations comprising the collisional collage are significantly different in composition and protoliths, and combinations of numerous shifted beds give evidence of a 'bulldozer' effect caused by the collisional shock followed by movements of crushed components of the ocean-continent zone along the margin of the Siberian paleocontinent. As evidenced by the recent cross-section, deep horizons of the Early Paleozoic crust comprise the collisional system between the Siberian craton and the Olkhon composite terrain.Β A permanent inclusion in the collisional combinations of rocks are unusual synmetamorphic injected bodies of carbonate rocks. Such rocks comprise two groups, marble melanges and crustal carbonate melted rocks. Obviously, carbonate rocks (that composed the original layers and horizons of stratified beds) can become less viscous to a certain degree at some locations during the process of oblique collision and acquire unusual properties and can thus intrude into the surrounding rocks of silicate composition. Such carbonate rocks behave as protrusions or intrusions and contain inclusions of silicate rocks. Formation of marble melanges is a multi-staged process: they occur as early tectonic covers and, more often, accompany shear zones of large lengths, comprise late push-out nappes initiated by shear faults, participate in construction of ring and vortex structures that are generated by shearing in the geological medium of inhomogeneous rheology. In general, the available data give evidence of the fact that formation of synmetamorphic marble melanges is a direct consequence of the oblique collision geodynamics and a sensitive indicator of such a regime. A pure guesswork may suggest that the occurrence of the marble melanges can be associated with a catastrophic loss of viscosity of the carbonate rocks due to a sharp increase of velocities of shear deformations that accompanied the oblique collision
