New Paleontological and Stratigraphic Data on the Ryazanian Regiostage in the Oka River Sections (Central Russia)

Based on the study of cephalopods and bivalves, the paleontological characteristics of the Ryazanian (lowermost Lower Cretaceous) sections were supplemented in the stratoregion located in the Oka River Basin near Ryazan, Central Russia. The data obtained are important for the analysis of the stratigraphic position in subboreal sections of taxa known in the Arctic, and the subsequent qualitative development of the zonal level of scales for belemnites and buchias of the Jurassic-Cretaceous boundary interval of the Russian Plate.

Contubernium Ochevi (Porifera, Hexactinellida)

Among the Late Cretaceous Ventriculitidae, with the most simply constructed pariform skeleton, representatives characterized by unusual neoplasms were identified. On the paragastric surface after the lapel of these sponges (Contubernium), cone-shaped submodules are regularly based, the appearance of which is associated with incomplete blastogenesis. Paragastra of submodules are not associated with the atrium, therefore, Contubernium is considered as a perifrontal organism, occupying an intermediate position between single and modular forms of spongia.

Cyclostratigraphic Analysis of the Rock Magnetic Data on Maastrichtian of the Bodrak River (SW Crimea)

Measurements of mass magnetic susceptibility of 2 232 samples, collected in Takma and Chakhmakhly sections (SW Crimea, Bodrak river) through every 20 cm of thickness were conducted. The cycles, supposedly corresponding to the periods of long and short eccentricities of Earth orbit and its axis obliquity were detected by Fourier transform and wavelet analysis of obtained data. The average sedimentation rate (11.7 cm/kyr) was calculated.

Deep Fluid and Processes of Destruction and Fluidization in the Lithospheric Mantle

To date, the significance of geological processes induced by fluid activity in the crust and in the Earth’s lithosphere in general has been fully revealed. The role of fluid systems in the energy and matter flow transfer, as well as in the formation of the lithospheric deep modes, its lamination and decompression structures, becomes apparent in the light of current data.

Hydrogeodynamic Mode of Artesian Pools and Connection with Oil Content in Sediments

Hydrogeodynamic research of oil-gas-and-water complexes of wellknown provinces allow to forecast the zones of hydrogeological opening of bowels of the earth and physical properties of oils of the expected beds.

Geological and Geochemical Features of the Volcanic Complexes of the Lower-Taiga Area (Northern Primorye)

The Lower Taiga area is a part of the East-Sikhote-Alin volcanicplutonic belt (ЕSAVPB), located in the transition zone of the continentocean which has a very folded geological structure. The study of the geological and geochemical composition, structure and patterns of the placement of volcanogenic-sedimentary rocks of the Lower Taiga area (LTA) will significantly complement the data on the geological and geochemical features of the Mesozoic-Cenozoic stage of the formation of the ЕSAVPB.

Geological Structure and Prospects of Oil and Gas Content of Chembarsko-Petrovskaya Zone Dislocations of Ryazan- Saratov Mega-deflection

Up to the present time the territory of Ryazan-Saratov mega-deflection including dedicated to it Chembarsko-Petrovskaya zone of dislocations for oil and gas remains poorly studied by modern geological and geophysical methods of exploration and deep exploratory drilling. In this paper the characteristic of the geological structure of a complex of Paleozoic rocks and identified deposits and deposits discovered in the Devonian and Carboniferous oil and gas complexes in

Faunal Assemblage of the Maastrichtian – Paleocene Intervals of Volsk Depression

Terminal layers of carbonate rocks of Maastrichtian and lower intervals of Paleocene aleurite-pelitic formations are accessible for investigation in Krasny Oktyabr and Bolshevik quarries (Volsk Depression). In the bottom of the Paleocene accumulation of skeletons of calcareous and siliceous sponges has been confirmed, mollusk and elasmobranch assemblage has been determined. Biozonal stratification of the location section and oryctocomplex analysis have contributed to specification of the processes in succession of benthic forms at the Upper Cretaceous – Paleogene boundary.

Mobile Forms of Heavy Metals in the Soils of the Town of Volsk (Saratov Region)

The concentrations of mobile forms of heavy metals (copper, nickel, zinc, copper, lead and chromium) in the soils of the town of Volsk (Saratov region) were determined. It has been established that the concentration of heavy metals (nickel, copper, lead and zinc) exceeds the maximum permissible concentration. 94% of the selected samples are related to the permissible level of pollution, 4% to the moderate level and 2% to the dangerous level. Thus, it can be noted that the occurrence of anomalous zones with a dangerous level of pollution is observed on the territory of the town of Volsk.

Organic Matter in the Soils of the City of Volsk (Saratov Region)

The concentrations of organic matter in the soils of Volsk (Saratov region) are determined. It was found that the concentration of organic matter varies from 0.57 to 2.34% with an average value of 1.88%. The distribution of organic matter in the background area varies from 2.03 to 2.33% with an average value of 2.25%. Thus, it can be noted that in the city of Volsk a decrease in the content of organic matter is observed in comparison with the background values.
