One of these structures in the south-east of the Karelian craton is Windy belt. To determine the effect of later tectonic movements on this structure the study of developing structural forms was realized. In morphostructure of Windy belt the real-structural heterogeneities of the geological base, recycled by Neogene-Quaternary tectonic movements, are appearing.

(Geologorazvedka) // vshuval-sergeev@yandex.ru FEATURES OF COMPUTER PROCESSING OF MAGNETOPROSPECTING DATA BY SEARCHES OF CHROMITES WITHIN ULTRABAZITOVY MASSIFS OF POLAR URAL MOUNTAINS The technique reduces effectively the impact of random component (signal-to-noise ratio) and keeps the most informative components of geophysical data during their processing. The processing technique includes three stages. In the initial stage the extremely high values are eliminated before the gridding of data. In the second data filtering stage takes place along the profiles. The size of the filter does not exceed the distance between the profiles. In the third stage 2D-filtration is performed after the gridding. Simulation of noise is used to estimate the informational content of the components and transformations of data. The results provide a basis for the further development of computer processing technology profile of geophysical data. Key words: magnetic observation, technique, variability of data structural components. Р. 38-43 |

(SRCES RAS) // a.a.tronin@gmail.com APPLICATION OF INFRARED-THERMAL SATELLITE FLOWN SURVEY ON THE LOW TEMPERATURE THERMAL WATER EXPLORATION The I.I. Nikshich hydrostatic model of low temperature hot water springs formation is used. We demonstrated that underground waters, uplifting along tectonic faults with the speed higher than 10-7 m/s, could heat a surface up to few degrees of Centigrade. Thus, the infrared-thermal satellite flown survey provides possibility to explore effectively the low temperature thermal water resources outside of regions of modern volcanic activity. As a result, specially drilled shallow boreholes at the territory of South Ural Mountain Ridge produced enough output of low temperature thermal waters. Key words: geothermal energy, heat pump, thermal waters, genesis, uplifting fluids, infrared-thermal satellite survey. Р. 49-57 |
