(IGEM RAN) // vlad243@igem.ru GOLD ORE DEPOSIT RADUZHNOE (KABARDINO-BALKARIAN REPUBLIC) The structure of the ore field of the Raduzhnoe deposit is a set of closely located ore zones, connected by the unity of their geological structure and by common origin within the boundaries of the general area of ore-localization. The Raduzhnoe deposit presents a hydrothermal object in subvolcanic structure and represents an ore-magmatic unit consisting of a series of ore bodies and subvolcanic bodies of medium-acid composition. Vein-like, stock-shaped and nest-shaped ore bodies with disseminated sulphide ores are developed in polygenic breccias, lenticular bodies of massive, densely disseminated sulphide ores and various of veins. The composition of the ores: pyrite, chalcopyrite, sphalerite, galena. Native gold is thin and low grade. It is presented in free form and in a finely dispersed form in sulfides. Keywords: gold ore deposit, North Caucasus, geology, ore. Р. 3-9 |

Nickeline, maucherite and sulfoarsenides of the cobaltite–gersdorffite series are non-magmatic in origin and were formed as a result of metasomatic replacement of minerals of both the Cu-Ni sulfide association and the earlier arsenide-sulfoarsenide stages. Keywords: nickeline, maucherite, gersdorffite, cobaltite, metasomatic replacement, sulfide Cu-Ni ores, Sedova Zaimka intrusion. Р. 9-18 |

УДК 577.4 (553.5) Gulynin A.V. (VIMS) // lab@u238.ru Petrochenkov D.A. (MGRI-RGGRU) // p-d-a@mail.ru RADIATION CHARACTERISTICS OF JEWELERY-ORNAMENTAL AMMONITE Ammonites and accompanying types of jewelry and ornamental raw materials (septaria, fossilized concretions, spectropyrite, sengilit, fossilized wood, fossils of marine reptiles) are widely used in jewelry, interior products, as a facing material. A detailed estimation of their radiation characteristics was carried out for the first time. In the ammonites of the apatite-calcite composition of a number of objects, the values of the isotope 226Ra and Aeff are 3-4 times higher than typical indices. Electron microscopic studies in ammonites have established uranium oxide, monazite, with which high radionuclide contents can be associated. Carried out researches did not establish the excess of the standardized radiation indices, which makes it possible to use the considered materials without restrictions. Keywords: ecological assessment, radiation characteristics, ammonites, jewelry and ornamental materials. Р. 18-21 |

Of critical importance in this regard is a problem of reducing exploration costs by focusing efforts on studying the most viable prospects. In order to rank promising oil and gas zones, assess resources and geological risks, LLC Gazpromneft STC uses numerical modeling of petroleum systems. In this article, we look at offshore projects to show how modeling helps solve multi-level geological problems depending on the knowledge gained about certain areas as well as the amount and quality of input data.

(Platov South-Russian State Polytechnical University (NPI) // 13050465@mail.ru THE TECHNOLOGY OF DOWNHOLE MINING OF IRON ORE WITH THE USE OF GEYSER PUMPS FOR PULP LIFTING The article shows that the use of the Geiser pump instead of the air-lift unit as part of the hydraulic unit GDA-600, operating with the NBT-600 medium-capacity drilling pump, allows to reduce drive power and energy consumption for lifting the pulp from 40 to 15 kW, but this cannot significantly affect the effectiveness of the GDA-600 as a whole. The layout of the GDS with the drilling pump UNB-1250 with a feed Qp = 51 l / s and two pumps of the Geiser with dimensions allowing them to fit into the GDA-1250 structure is considered. At the same time, the productivity of the hydraulic unit increases from 41,5 tons (when equipped with a pump NBT-600) to 58 tons of ore per hour, i.е. more than 1,4 times.
