(IMGRE, JSC «PAVLIK)//grigorovrim@mail.ru A NEW LOOK AT THE NATURE OF THE GEOCHEMICAL FIELD AND THE HALO-FORMING SYSTEM As a result of the study of the structures of geochemical fields of metallogenic and ore objects, a new type of spatial relationship of geochemical fields has been discovered, independent of the composition of the host rocks and the scale of manifestation – synchronous zonality. During the evolution of the geochemical field, its intensity increases with a proportional decrease in size. The primary geochemical field has a physical nature and is associated with deep planetary processes that form magmatic foci and tectonic structures in the processes of dissipation and concentration of endogenous energy. The application of established patterns in practice leads to a sharp increase in the efficiency of prospecting and exploration works. Keywords: geochemical field structure, synchronous zonality, metallogeny, ore formation, evolution, concentration, dissipation, prospecting, exploration. P. 3-7 |

The results of the mineragraphic analysis of lamprophyre dikes show that they often contain magnetite, rutile, iron hydroxides (goethite, limonite), pyrite, and rarely – chalcopyrite, arsenopyrite, native gold, native silver, pyrrhotite, etc. According to the distribution of the main elements, lamprophyres are potassium calc-alkaline, high-alumina and leucocratic intermediate rocks, low transition element contents reflect that the rocks have hybrid magma characteristics. Compared to mid-ocean ridge rocks (MORB), lamprophyres are enriched in Ba, Cr, Mo, Hf, U, Pb, Au, Ag, Cd, As, Se, Bi, etc., and depleted in titanium, iron, and magnesium oxides. Keywords: mineragraphy, petrogeochemistry, ore minerals, elements, lamprophyres, diorite porphyrites, syenodiorites, western flank of the Pistali gold deposit, Northern Nuratau. P.7-17 |

It is shown that under the influence of external tectonic forces, the current geodynamics of the deflection is determined, expressed by the activity of north-eastern faults, the formation of small folded dislocations and the concentration of tension in the zones of curvature, intersectionality and conjugation of faults. Keywords: geodynamics, deflection, structure, plate, deformation. P.24-26 |

(National Research Tomsk Polytechnic Universit)//pere-elena@mail.ru THE COMPARATIVE ANALYSIS OF GROUND AND MIRE WATERS IN THE SOUTHEAST PART OF THE WESTERN SIBERIA The statistical analysis of the data on a chemical composition of mire and ground waters in areas of accommodation of ombotrophic, mesotrophic and eutrophic types, located in sub-taiga and southern-taiga subzones of the Western Siberia (the south and a southwest of the Tomsk area) is carried out. It is shown that the most expressed influence of ground waters on a chemical composition of mire waters typically for eutrophic fens where there is a unloading of pressure head ground waters. The chemical composition of waters of ombotrophic bogs significantly is not connected to a condition of ground waters as a whole. Keywords: chemical composition, mire and ground waters, the comparative analysis, the Western Siberia. P.26-33 |

In terms of cost / labor and financial costs, the most promising is the use of deuterium, oxygen-18 and tritium. The insufficient number of qualified specialists and the lack of a regulatory framework for their application, which urgently requires the introduction of appropriate courses in the basic educational programs of universities, hinder the practical implementation of isotope methods.

For the first time, it was established that when used independently, glycine works in both alkaline, acidic and neutral environments. The obtained results showed stability of rock-forming minerals to glycine solutions. Ore minerals of oxidized gold and copper ores, especially copper carbonates (malachite, azurite), have the highest leaching rate and minerals of secondary enrichment zones. Keywords: glycine, alkaline aqueous medium, slightly acidic aqueous medium, neutral aqueous medium, leaching, ore and rock-forming minerals. P. 38-49 |

JUSTIFICATION OF THE EFFICIENCY OF PROTECTION OF BEDROOMS DURING UNDERGROUND MINING OF ORE DEPOSITS The substantiation of the effectiveness of protection of subsoil in the underground mining of ore deposits by traditional technologies and combined with the leaching of metals from rocky substandard and off-balance ores is given. This will ensure an increase in economic efficiency, rational use and protection of the subsoil, as well as increase the raw material base for the extraction of metals at operating mines by 1.4–1.6 times. A methodology for determining the efficiency of underground mining of ore deposits by comparing the indicator of the completeness of the extraction of a useful component from the subsoil using traditional and combined technologies is presented. Keywords: underground mining, metal leaching, substandard ores, efficiency. P.50-59 |
