Ground penetrating radar (GPR) became very popular in the last decade in Russian federation. Not only scientific publications have been devoted to GPR but also articles in the press and TV programs on federal and local channels. Three directions of georadiolocation are considered in the article, which seem promising to the authors and will develop in the future: GPR ray tomography, GPR application with other geophysical methods and GPR using in permafrost regions. Examples of application of different methods of GPR data collection and processing are considered.
The shortening deformation value was estimate in Lower and Middle Jurassic terrigenous rocks of the Northwestern Caucasus (Belaya River valley) using cleavage morphology. Numerical definition of deformational ellips’ axis ratio were obtained using Fry method «centre-to-centre» additionally. This paper shows that the deformational value may be quantitate correctly for random cross-section series of cleavage terrigenous rocks. The non directional random crosssection method described here can be used to quantify the shortening deformation of statistically significant sample series.
In this work we reported the structural features and mechanism of the formation of the Simskaya low of the Uralian foreland basin, besides the Karatau-Suleyman block as a whole. This block has the shape of a wedge, so with a general latitudinal compression, it experienced lateral extrusion to the north along the conjugated shear zones. This factor determined the local situation of meridional compression and latitudinal tension. In the central part of the block, the latitudinal stretching was compensated for by gradual deflection, which led to the formation of the Simskaya low.
The analysis of geological and geophysical materials in order to study the peculiarities of the geological structure of the Vikulov Formation within the Vodorazdel license area was carried out. The presented factual material makes it possible to characterize the geological structure of the investigated area more informatively and for interpreting of seismic materials. The analysis of geological information (GIS and test results) confirms the approved water–oil contact (WOC) level in the investigated section of the deposit, which makes it possible to recalculate its reserves.
To identify geochemical zoning of the Peschanka porphyry-epithermal system geochemical and mineralogical data for 266 drill holes were used. By means of factor analysis and GIS software 3D geochemical model was developed to map spatial distribution of elemental associations and mineral assemblages. Lateral and longitudinal zoning patterns were described. The ratio AgPbZn:CuAuMo was suggested as an indicator of vertical zoning allowing assessing erosion level of porphyry copper stockworks.
Analysis of tectonic displacements along fractures and faults enabled to reveal changes in character of tectonic deformations resulted from tectonic evolution of the Magnitogorsk island arc. Structural conditions of localization of ore mineralization of various types were investigated in the open pit of the Dzhusa deposit. The ore shoot on block diagram of the deposit coincides with intersection of NW-trending and sublongitudinal faults. Trends in distribution of enriched mineralization are slightly different for various metals. The data obtained enable to predict position of rich ore bodies at deeper levels of the deposit and help in prospecting for new deposits in the Terensai ore field.
The ecological and geological respect dirt sand stratum is considered as a component of ecological and geological systems or biogeocenoses. The characteristic ecological-geological features of sand massifs are considered. Type sand structure of sandy ecological-geological systems are distinguished.
The article contains materials on the study of landslide deposits in the upper reaches of the Mzymta river basin. The results of 14C analysis showed that the youngest landslides are common on the southern slope of the Psekhako Ridge and date back to less than 200 and 390±90, 400±70 years ago BP and more than 770±150 years BP. The most ancient landslide-collapse on the northern slope of the Aibga Ridge and dates back to 1110±90 years BP.
This study shows the experimental results of the rare earth element and Y (REY) distribution patterns between heterotrophic bacteria and water under acidic pH conditions for five different bacterial strains (Microbacterium sp., Curtobacterium sp., Bacillus subtilis, Pseudomonas putida, Bacillus pumilis) which are widespread in natural and technogenic ground- and surface waters of the Far East of the Russian Federation. The insignificant distribution pattern between heavy and light REE, a negative Ce and Dy anomalies and a positive Eu anomaly were found. It was discovered the selectivity of the REY biosorption by the Gram-positive and Gram-negative bacteria and the time response of the biosorption process in a more acid environment.
The geological structure of the water area adjacent to the White Sea biological research station of the Moscow State University (the Rugoserskaya bay and the Great Salma strait, the Kandalaksha gulf of the White Sea) was examined for the first time basing on seismoacoustic data. The morphology of top of the Archaean basement, the structure of the Quaternary sedimentary cover and the bottom topography were studied. A sequence of glacial deposits dating back to the last glaciation and a compound sequence of glaciolacustrine, glacial-marine and marine sediments were delineated. Spatial configuration and thickness behavior were examined. It was demonstrated that the recent bottom topography is controlled by the faults, characterized predominantly by north-western and the north-eastern strike, and affecting the entire sedimentary cover including the Holocene sediments.
Diffusion and adsorption (DA) potentials are frequently the sources of self-potential anomalies, but they not arouse such practical interest as anomalies of red-ox and filtration origin. DA anomalies can be found everywhere and geophysicists sometimes make mistakes considering DA anomalies as examples of filtration anomalies. Identification of DA anomalies is based on correlation of SP and apparent resistivity values along the same profiles. At MSU students geophysical practice in Kaluga region we obtained profiles with SP and resistivity anomalies with good correlation between them. That fact allows consider such SP anomalies as a result of DA processes.
This paper deals with the complex geophysical studies carried out to determine the nature of the intense magnetic anomaly identified by the results of ground surveys on the right bank of the river Slushka on the territory of Yukhnovsky district of Kaluga region. Integrated interpretation of geophysical data and laboratory core measurements allowed to define the nature and parameters of the anomalous object located in the upper part of the section and presented by loam containing such magnetic minerals as greigite, pyrrhotite and magnetite.
SHORT MESSAGES
The possibility of using of dolomitic geochemical barrier to integrated treatment from fluorine of the alkaline waste water of coal heating enterprises was experimentally proved. It was established that residual fluorine concentration at pH 10,4–10,6 conforms to the optimum for drinking water (0,7–0,9 mg/l) whereas degree of fluorine removal from solution at pH >12,0 is maximal and makes 99,2% at the residual fluorine concentration <0,1 mg/l. The optimum residual fluorine concentration is reached at the stoichiometric surplus of dolomite above reactive CaO in ashes and slag waste. It allows to calculate necessary capacity of the dolomitic barrier on chemical composition and intensity of formation of the last.
