(VIMS) // vims-rudnev@mail.ru ORE-BEARING OF THE MESOZOIC TECTONICMAGMATIC ACTIVATION AREA OF THE EASTERN SIBERIA AND THE FAR EAST The location and formation conditions of the main ore objects of the Mesozoic tectonic-magmatic activation area (TMA) of the Mongol-Okhotsk belt and adjacent territories are considered. Analysis of the ore-bearing is presented sequentially within the largest taxa of the TMA: activated structures of the MongolOkhotsk belt proper, the adjacent to the north southern margin of the Siberian craton and the Sikhote-Alin fragment of the West Pacific belt. It is shown that there are age and geologicalgenetic specificities of ore objects for each taxon. The considered ore formation conceptual models can be used as a methodological basis for predicting of the new objects of a predominantly hidden type. Keywords: tectonic-magmatic activation, MongolOkhotsk and Pacific belts, plutonic-volcanic processes, collision, accretion, ore formation. Р. 5-17 |

Based on the results of the analysis of the obtained data, individual minerals and groups of minerals were identified that mark the intervals of increased gold contents in the deposit. Keywords: hyperspectral IR spectroscopy, Vis-NIRSWIR spectroscopy, hydrothermal-metasomatic changes, diagnostics of clay minerals, modern methods of mapping metasomatic changes, metasomatic zoning, epithermal gold deposits.

It has been shown that the Bazardara complex is predominantly represented by sedimentary-metamorphic rocks, among which plutonic formations of medium and acid composition are found in subordinate quantities. Almost all silver ore occurrences are localized within the granitoids yields of the Bazardar complex. This also applies to rare-metal-tungsten-tin formation and other mineral formations. The rocks of the complex are the main ore-bearing formations. Keywords: Akjilga, Bazardara complex, granite, intrusive rock, Bazarik, Bazardara massif. P. 24-30 |

Modern modifications of airborne geophysical methods and their development prospects are considered, as well as features of using airborne geophysical technologies at different stages of geological prospecting. Modern approaches to geophysical modeling and complex data interpretation are analyzed.

Mathematical processing and statistical analysis of the kinematic and dynamic attributes of GPR signals allowed the construction of structural and petrophysical models. On the basis of them, the main features and details of the very complex structure of the final engineering and geological model of the frozen ground base of the road are described. The error of the depth of the lithofacies and cryogenic (by temperature and iciness) boundaries of the frozen soils of the lake-swamp and alluvial genesis in 70% of cases amounted to ± 0.42 m. Keywords: road, frozen soils, borehole, GPR, depth, delay time and pulse amplitude, attenuation coefficient, models. Р. 40-48 |

(Russian Energy Agency) // Zhdaneev@rosenergo.gov.ru Kononenko V.A. (RN-GRP (Rosneft)) // VKononenko@rn-grp.ru ON PRIORITY DIRECTIONS OF DEVELOPMENT OF GRP TECHNOLOGIES IN RUSSIA The paper covers the technical requirements for the future hydraulic fracturing fleet (operations / process and equipment) and its potential architectural structure. The critical importance to define the most promising architecture of the hydraulic fracturing fleet is a large-scale transition to the oil and gas production from unconventional reserves. This transition is due to a decrease in the level of production from traditional reservoirs and the target indicators of the Energy Strategy of the Russian Federation until 2035. A prospective hydraulic fracturing fleet should be able to perform work in an automatic mode with a pumping rate of up to 18 m3 /min, at working pressure of up to 100 MPa. The nature of the injection can vary depending on the properties of the reservoir, the proppant, fluid and specialized additives supply system must provide both pulsed and continuous injection into the formation. Keywords: hydraulic fracturing, hydraulic fracturing fleet, production stimulation, hard-to-recover reserves, unconventional reserves. Р. 49-57 |

The first of these reasons is determined through the interrelation with solar activity, while the second one through the correlation of significant displacements of landslides with distant seismicity and on a trigger effect of process appearance. It is proposed to create a comprehensive geophysical testing ground to study the impact of meteorological and seismic processes on the level of landslide activity.

(Rosgeologia) // dz_geo@mail.ru TO JUSTIFY THE CREATION OF A UNESCO GEOPARK IN RUSSIA (ON THE EXAMPLE OF THE ICHALKOVSKY CAVE COMPLEX IN THE NIZHNY NOVGOROD REGION) In 2015, at its 38th session, UNESCO approved a fundamentally new type of protected area — the UNESCO Global Geopark. Currently, this direction is intensively developing in the world, more than 140 Geoparks have been created in 41 countries. There is only one geopark in Russia — «YanganTau» in Bashkiria. There are all the prerequisites for the creation of other Geoparks in our country. One of the promising objects is the Ichalkovsky cave complex in the Ichalkovsky relict forest of the Nizhny Novgorod region. The prerequisites for the creation of a UNESCO Geopark on its basis are considered. Keywords: cave complex, karst, relict forest, geopark, stratigraphic zone, flora and fauna. P. 64-66 |
