(Geological Institute KSC RAS) // petrovskaya@geoksc.apatity.ru CONDITIONS OF EXCESS PRESSURE GENERATION DURING THE FORMATION OF STRUCTURAL-MATERIAL COMPLEXES WITHIN SHEAR ZONES (KOLA PENINSULA) The performed numerical simulation allowed to physically substantiate the mechanism of the excess pressure generation in shear zones during shifts of rigid crustal blocks. It has been shown that increased pressure values may be provided at a relatively low depth in inter-bloc plastic rocks due to shear movements of the crust segments regarding each other. The pressure distribution in the layer is non-linear and depends on the speed of block motion and layer thickness and the viscosity of its rocks. Keywords: Baltic Shield, Neoarchaean, Earth’s crust, metamorphism, thermodynamic conditions, shear zones, numerical modeling. Р. 3-7 |

The level of protection of marsh complexes in the Republic of Bashkortostan was estimated. The principles of excretion of territories having natural value and claiming for status of specially protected natural area were characterized. The procedure for determining the boundaries of security zones was consedered. Economic estimation of ecosystem services of peat bogs of forest-steppe and steppe zones of the Republic of Bashkortostan is carried out.

(Resurs LLC Coal Company) // oxotnikow@mail.ru SPECIAL FEATURES OF IDENTIFICATION OF PROCESS GROUPS IN COAL GRADES WHEN ESTIMATING RESERVES The norms and specifications have been reviewed that regulate the identification of process groups and the types of coal and ore have been compared in terms of natural and industrial types. It has been determined that the difference of industrial (process) types of ore and coal is conditioned by the degree of processing to obtain finished product, while the guidelines of the State Committee on Reserves lack the qualitative parameters for the conditions to identify the process types of coal. It is suggested, that the reserves of coking coal should be identified as carbon forming (premium) and process (valuable), while the thermal coal should be identified as energy-technological and fuel. Keywords: study reliability, grade composition, conditions, quality, process property, natural type, industrial (process) type, grade, value. Р. 42-48 |

(Rosnedra) // amorozov@rosnedra.gov.ru UNDERGROUND DISPOSAL OF INDUSTRIAL WASTES – HYDROGEOLOGICAL FUNDAMENTALS, USE EXPERIENCE, CONTRADICTIONS OF NATURE PROTECTION LAWS The problem of underground disposal of industrial wastes was considered, hydrogeological fundamentals of underground disposal of liquid industrial wastes including radioactive wastes were described, examples of practical results were given regarding disposal of liquid wastes of nuclear and chemical industry in Russia. It was indicated that standard methodical and cartographical database was formed in Russia. It provides practical use of underground disposal of dangerous wastes including radioactive wastes. Also it has to be pointed that some of “Environment protection” law and “Water code” articles actually have restrictive essence regarding disposal of toxic and radioactive wastes which is absolutely absurd considering initial orientation for nature preservation of this method. It was approved by legislators themself during special parliament hearings in 1997. It was stated the importance of creation of atlas of specialized maps reflecting conditions of dangerous industrial wastes disposal in different aggregate states within the territory of each federal region of Russia. Keywords: disposal of toxic and radioactive industrial wastes, liquid wastes, atlas of specialized maps of Russia’s territory regarding conditions of industrial wastes disposal. Р. 48-54 |

(Singeos) // singeos@narod.ru GEOECOLOGICAL ESTIMATION OF LARGE BLOCK LANDSLIDES OF THE MOSCOW REGION Search algorithms of the displacement zone with the minimum stability coefficient in stage-by-stage computer simulation methods and other geological and geodesic information are used. The emergence and development of large block landslides in the Moscow region are based on the classic shear mechanism. Total duration creep period was estimated and the impossibility of spontaneous decay is showed. The measures for monitoring and engineering protection against these landslides in the conditions of the geoecological situation of the megalopolis are proposed.
