A.A. Predovsky, I.V. Chickiryov, D.A. Nekipelov RIFT ZONES AND RIFTOGENES FROM THE TYPOLOGY OF CRUST STRUCTURES The study is based on the morphostructural analysis and on the idea of mantle-crust interaction. The rift systems of continental and oceanic types are characterized. Keywords: rift zones, mantle-crust interaction, typology of crust structures. N.E. Kozlov, E.V. Martynov, N.O. Sorokhtin FORMATION CONDITIONS’ RECONSTRUCTION FOR EARLY PRECAMBRIAN COMPLEXES (NEW APPROACHES) The paper discusses the problems of reconstruction proto nature and conditions of formation of complexes of ancient protoliths. Attention is drawn to the fact that the processes of developing nonlinear evolution of the Earth, which imposes restrictions on the use of the principle of actualism. A technique for data processing and interpretation, taking into account changes in the chemical composition of the mantle. An example of the use of an amendment to the evolution of matter in the reconstruction of a primary nature and conditions of formation of protoliths of early Precambrian complexes. Keywords: regional geology, geochemistry, Precambrian complexes, protoliths, reconstruction, metamorphism, geodynamics, volcanism, sedimentogenesis. A.I. Kalashnik, D.V. Zaporozhets, N.A. Kalashnik IDENTIFICATION OF FILTRATION-DEFORMATION PROCESSES IN THE BODY OF PROTECTING DAM OF ENRICHMENT TAILS STORE Regime georadar researches of structure of a dam store of Enrichment tails with a view of identification of filtratsionno-deformation processes in its body are executed. During the supervision, made about two months, it is allocated three types of a condition and various filtrational heterogeneity soils dams: insignificant fall of a water level; considerable fall of a water level and practically without change. The zone underground suffusion washout soils is revealed and tracked in dynamics. Keywords: georadar researches, dam, filtratsionno-deformation processes, suffusion washout. P.V. Amosov NUMERICAL SIMULATION OF TEMPERATURE DISTRIBUTION OF A RADIATING PLATE A well-known method of heat generation release out of space module board by means of fridge- radiators is analyzed using numerical simulation. Examples of numerical solutions for thermal problems containing definite set of variable parameters (material, sizes and emittance of a surface) are presented. The comparison of the results of numerical simulation and their analytical estimates were in satisfactory fit for the plate minimal temperature. Influence of the length, width and emittance on the minimal temperature is shown for the iron plate. Keywords: radiation in vacuum, numerical simulation, thermalphysic parameters. N.A. Kalashnik ON SOCIAL AND ECONOMIC CONSEQUENCES OF FAILURES AT SHELF OIL AND GAS DEVELOPMENT The most typical cases of extreme situations and failures are considered at shelf oil and gas development. The statistical analysis of events and the social and economic damage caused by them is made. Methodical approaches to an economic estimation of consequences of emergencies and expected profit oil and gas development taking into account risk of extreme situations and failures are offered. Keywords: oil and gas development, a shelf, failures, social and economic consequences. N.M. Adrov MARINE BIOLOGISTS TO CHEMISTRY OF THE OCEAN The main indices of the biohydrochemistry regime of water masses, namely linear connections of concentration of dissolved oxygen and temperature of water, revealed in different layers of the aqueous depths of the ocean, are examined based on an example of bio-oceanological studies. A model is proposed for evaluating physical and biochemical components of the thermo-oxygen transformation of water masses. Keywords: biohydrochemistry regime, thermo-oxygen transformation, advection, convection, oxygen budget, saturation hysteresis. 131
