(VIMS) // prydnukov@gmail.com GENETIC TYPIFICATION OF DUNITES OF ALPINOTYPE MASSIFS BASED ON THE NATURE OF THE DISTRIBUTION OF RARE EARTH ELEMENTS The distribution of rare-earth elements on a representative batch of samples from of dunites of alpinotype ophiolites of the Urals belonging to different types of oceanic lithosphere — lherzolite, harzburgite and dunite-harzburgite — is studied. The distribution of rare-earth elements characterizes the development in the ophiolite massifs of nine types of dunites formed during the processes of depletion, refertilization (mantle metasomatism) and magmatic differentiation of percolated melt. It is shown that dunites of various genesis are rather confidently discriminated on the diagram LaN/YbN to ΣREEN. Keywords: ophiolite massifs, Nurali, Rai-Iz, Voikaro-Synyinsky massif, dunites, ultrabasic rocks, rare earth elements, mantle metasomatism, refertilization, depletion, genesis of ultrabasites.

УДК. 550.4.02 Grigorov S.A. (IMGRE) // grigorovrim@mail.ru ORE FORMATION, AUREOLE FORMATION AND PRINCIPLES OF METALLOGENIC MAPPING AS A BASIS FOR PROSPECTING FOR ORE DEPOSITS The innovative technology of prospecting for ore deposits is based on the use of fundamental signs of self-organization in the geochemical field by the method of structural and geochemical modeling of the hierarchical ore — ore-forming system. The criteria of self-organization are the concentric structure of the AGCP, synchronous and lateral zoning in the context of fractal fractionality, formed in the conjugate processes of scattering (dissipation) and concentration of chemical elements, regardless of the ore specialization and the structural and material composition of the host medium. An example of effective implementation of the technology is given. Recommendations are given in terms of changing the fundamentals of geochemical prospecting and metallogenic mapping. Keywords: self-organization, dissipation, concentration, structure of the geochemical field, search for ore deposits, taxa, hierarchy, metallogenic mapping. Р. 26-32 |

The article presents the current state of the tectonic structure and characteristics of ruptures in the southwestern part of the Hissar mountains, exploring mainly flexural-rupture zones, large jumps of uplifts and subsidence, surface displacements developing in the northeast, also southwest directions. The reasons are presented and large structural units with overlapping zones of multiple ruptures are identified.

(North Caucasus Federal University) // i.pomelyayko@yandex.ru THE OPERATIONAL MODE MANAGEMENT UNDERGROUND WATER OPERATIONS A technique is proposed for the operational management of the operating regimes of underground water deposits (plots) based on hydrogeological monitoring. The essence of the method is to formulate the objective function and justify the method for predicting the dynamics of the development of hydrogeological processes. The advantage of the method is explained by independence from the terms of the field’s exploitation, the speed of making changes to the mode of operation, depending on the actual mode, even when the object is not sufficiently studied, since geological information is very expensive, and you have to deal with her deficit. Keywords: operational management, hydraulic forecasting methods, mathematical modeling, objective function, geological and ecological zoning. Р. 41-47 |

On this basis, taking into account the elements of the occurrence of aquifers, the direction of movement of water in them, a circulation system for the development of underground water deposits by injection forced self-pouring was formed.

(MGSU) // KrinochkinaOK@mgsu.ru THE PROBLEM OF NORMALIZING GROSS CONCENTRATIONS OF HEAVY METALS WITHIN THE WESTERN SLOPE OF THE SURA-SVIAZHSKY INTERRULE OF THE VOLGA ELEVATION AND MARI LOWLAND Studies are given on the gross forms of some metals in the soils of the western slope of the Sura-Sviyazhsky interfluve of the Volga Upland and the Mari Lowland. Comparison of data with UDC. The problem of rationing pollutants is posed. It is proposed to consider landscapes weakly damaged by man-made activities in comparison with background data. As markers of initial degradation, metals were used: copper, lead, zinc, nickel. An increased concentration of copper in the soils of weakly damaged landscapes of the humus-accumulative horizon was recorded, twice as much as UEC. Zinc concentration exceeded UEC in all samples of «reference» and slightly damaged landscapes by 1.5–2.5 times. Increased zinc concentrations are most likely associated with contamination of the territory with municipal waste. Nickel concentrations exceeded UDC 4.5–6 times. The main source of nickel entering the soils is the exhaust gases of vehicles. Thus, weakly damaged landscapes were characterized by an excess of UEC for copper, zinc, nickel. Keywords: heavy metals, Sura-Sviyazhskoye interfluve of Volga Upland, UEC, MPC, background data Р. 56-59 |
