УДК 725.945.1:55 Pechenkin I.G. (VIMS) // pechenkin@vims-geo.ru MEMORY AND SORROW FROZEN IN BRONZE (THE HISTORY OF THE CREATION OF THE MONUMENT «GEOLOGISTS WARS, 1941–1945») In the first two weeks of World War II, a large group of VIMS specialists went into the army and the militia. 26 of them died. Erected in 1955, a stele commemorates the dead employees of the institute, has become a symbol of our invincibility. At the end of 1979, at the suggestion of the VIMS Veterans Council, a decision was made to reconstruct the monument. The monument was erected from bronze and red granite from Suskjuansaari deposit, since 1986 — the center of the annual celebration of Victory Day by the geological community of Moscow. Keywords: The Great Patriotic War, VIMS, granite, Suskuyansaari. p. 3-9 |

(MGRI-RGGRU) // eiromanova@hotmail.com PERICLASE IN MAGNESIAL SKARNS OF ABYSSAL FACLES OF KUHILAL DEPOSIT, SOUTH-WEST PAMIR The Deposit of jeweler spinel, forsterite and clinohumite is localized In The South-Western Pamir, which has undergone metamorphism of granulite, high-temperature amphibolite, epidote-amphibolite and green shale facies. A periclase is installed in the Main zone of magnesian skarns. It forms three parageneses: periclase + forsterite, periclase + spinel, and periclase + clinohumite. Periclase which is «forbidden» for high-pressure conditions of metamorphism was formed in magnesian skarns of abyssal facies not by reaction of decarbonatization of magnesian carbonates, but as result of replacing minerals of sulphates and chlorides of magnesium. Brucite which is widespread in the Deposit, is formed by hydration of periclase, but not by substitution of spinel as previously thought. This is confirmed by the absence of aluminum oxides, which would originate with replacing spinel, but they are not in paragenesis with brucite. Periclase can be considered as an indicator of the presence of magnesia sulfates and chlorides in the evaporite proto-matter of the Kuhilal Deposit. Keywords: South-Western Pamir,goran series, magnesian skarns, magnesian sulphates, periclase. p. 30-34 |

The formation of hydrogen sulfide as a result of thermochemical reduction of sulfates by methane at a temperature of about 80–100 °C of gas fields in the Bukhara-Khiva basin is confirmed by experiments conducted by S.M. Grigoriev, Sakai (Sakai H., 1957), S.D. Malinin and N.I. Khitarov (1969). Surkhandarya artesian basin. The hydrodynamic pressure of groundwater in the eastern part of the artesian basin is present due to tectonic disturbances and a weak slope of the sedimentation. As a result, microbes (organic substances) are excited in the oil column, sulfate-reducing processes occur and, as a result, the hydrogen sulfide waters of the Paleogene are formed. Ferghana artesian basin. The water pressure system is more active in the oil and gas fields on the southern side of the Fergana Depression due to the Paleogene sequence lying close to the earth’s surface, steeply going to a depth along the slope of the hollow and crossed by a group of longitudinal tectonic faults. Average temperatures of the productive horizon of oil and gas deposits on the southern side of the Ferghana Depression, where hydrogen sulfide waters are formed, range from 28 to 48 °C. Keywords: formation temperatures, piezometric pressure, productive horizon, gas and oil field, artesian basin, thermochemical process. p. 34-46 |

Obtaining conditioned products as a result of the beneficyation of high-titanium ores at the present stage of development of beneficyation technologies is difficult. The process of roasting of titanomagnetite ores is accompanied by a redistribution of chemical elements and the formation of new, more stable phases with their subsequent enlargement. Thus, the separation of titanium-containing and iron-containing minerals occurs, which may have positively influence to their mechanical separation process. Keywords: heat treatment, iron-titanium ores, titanomagnetite, ilmenite, phase heterogeneity, structural heterogeneity. p. 47-52 |

This allows the uranium deposits to be effectively developed by the well-in-depth leaching (SPR). In terms of importance and complexity, RRW can be equated with work on the construction of SPR technology wells. RRW is divided into four main areas: maintaining and improving well productivity; repairing operating columns; extraction of foreign objects from wells; special work in wells. This work attempts to organize the types of RRW and identify the equipment required for each type of work. Keywords: well uranium mining; technological wells repairs and restoration work; equipment and a tool for repair and restoration work. p. 52-57 |

(TFGI For Volga Federal District, TSNIIgeolnerud) // tlir@inbox.ru ON THE NECESSITY OF AMENDMENTS TO THE LAW OF THE RUSSIAN FEDERATION «ABOUT THE SUBSOILS» IN PART OF COMMONLY USEFUL MINERLS In connection with the adoption in 2003 of Federal Law No. 131 «On General Principles of the Organization of Local Self-Government in the Russian Federation», adjustments were made in a number of federal laws. In the Law of the Russian Federation «About the Subsoils», currently in force since 1992, and for more than 27 years, structural changes have not been made in connection with the adoption of this law and the ongoing reform on the organization of local selfgovernment in the country. Currently, about 25 thousand local governments in the country, their vast majority of budgets are subsidized. One of the sources of replenishment of funds in the budgets of municipalities may be the development of deposits of common minerals, the number of which exceeds 20 thousand in the country. Based on the analysis from various sources, the importance of common minerals for various industries and agriculture is shown, their development can initiate socio-economic development of municipalities. At the same time, one of the constraining factors is the lack of a single conceptual terminological base in the Law of the Russian Federation «About the Subsoil» regarding common minerals. In this regard, amendments to this law are proposed. In addition, an inventory and certification of mineral resources related to common mineral resources are necessary to create an intersectoral technological map for obtaining liquidity of products. Keywords: common mineral resources, the subject of the Russian Federation, directions of use, the Law of the Russian Federation «About the Subsoil», adjustment, subsoil sections of municipalities, inter-branch technological map. p. 57-64 |

(MGRI-RGGRu) // khudoyorova09@mail.ru MODERN TECHNOLOGIES FOR CLEANING WATER BODIES FROM OIL-CONTAMINATED BOTTOM SEDIMENTS USING GEOCONTAINERS Bottom sediments of anthropogenic and natural origin worsen the environmental and sanitary status of waterbodies. When it is impossible to self-purify closed reservoirs from bottom sediments, a gradual siltation, overgrowing and formation of land from alluvial sediments and dead biomass during swamping the coast occurs. When cleaning waterbodies, dewatering of bottom sediments in geotextile containers is widely used. Keywords: bottom sediments, oil pollution, waterbodies cleaning, geo-container. p. 75-76 |
