The tectonics study of the area was aimed at studying the orientation and kinematics of ore-controlling and ore-bearing faults and fracture zones of rocks. Sukari gold mine area is complex Precambrian volcanogenic-terrigenous rocks, broken Granitic intrusions embedded a thick sequence of shales and serpentinites. The Sukari gold deposit is confined to an intrusive massif composed of granitoids and gabbro-diorites and consists of four ore-bearing zones stockworks structure, including gold contents. Gold-bearing quartz veins and veinlets are located in the apical part of the granite massif in the Hangingwall. at the contact with carbonaceous shale.

УДК 543.257? Bebeshko G.I. (FBU RFTSCE) // 109382@mail.ru Goleva R.V. (VIMS) VALUATION AND CONTROL OF HALOGEN CONTENT IN IRON-MANGANESE OCEAN ORES Mineralogical studies confirmed the presence of iron-manganese oceanic ores (ZMK and KMC) bound forms of halogens – a number of minerals, including chlorine, iodine. With the help of ionometric methods of analysis for the first time it was found that in the ore samples the content of bound fluorine is approximately at the same level, and the mineral forms of chlorine, bromine, iodine are much higher than the content in the rocks of the land, and differ markedly in relation to each other. A significant proportion of chlorine and bromine is easily soluble in mobile state, mainly in the composition of thalassogenic water in the near-surface zone of nodules. For a precise assessment of the content of ore components, it is necessary to control the content of easily volatile halogens, which have an interfering effect on the determination of hygroscopic moisture, and to estimate the total number of halogens in ores – to take into account the content of both forms of halogens. Keywords: bound mineral and mobile easily soluble forms of the halogens, oceanic iron-manganese ore (ZMK, KMC), mineralogical and ionometric methods of analysis, volatility of halogens. Р. 16-22 |

Results of the analysis using special hydrogeological map indicate areas of the entrails unpromising for disposal. Those areas were defined by the presence of high-contract helium anomalies. Also there are shown the entrails areas which demand high attention during detail research because of the presence of areas of high helium concentration above background level.

(Tatarstan branch FBI «TFGI in the Volga Federal District») // tfirt@inbox.ru TO THE QUESTION OF THE FEASIBILITY OF DEVELOPING A STRATEGY FOR DEVELOPMENT AND USE MINERAL RESOURCES BASE OF COMMON MINERALS IN THE SUBJECT OF THE RUSSIAN FEDERATION Common minerals are currently the underutilized resource of the mineral resource complex of the Russian Federation, to which the federal authorities on subsoil use show a clear lack of interest, and the subjects of the RF do not pay proper attention to this wealth of mineral resources. Based on the methodological techniques for the subjects of the Russian Federation on the basis of common approaches, it is proposed to develop a «Strategy for the development and use of the mineral resource base of common minerals» in the long term. Common minerals are extremely important for the socio-economic development of each subject of the RF, contribute to the growth of its economy, improve the quality of life of the living population, cash flow in the form of mineral extraction tax to regional budgets.
