MAYMINOVSKOYE POLYMETALLIC DEPOSIT (PRIMORYE): MINERAL ASSOCIATIONS, TYPOMORPHIC PECULIARITY OF ORE MINERALS AND ORE FORMATION CONDITIONS
Mineral associations, geochemical peculiarity of the main ore minerals and ore-forming conditions have been observed in ores of Mayminovskoe polymetallic deposit situated in the East Sikhote-Alin plutono-volcanogenic belt of Primorye. The new findings in galena und sphalerite under δ34S have been obtained, indicating the polygeny of ore formation sources. Thermobarogeochemical investigation on fluid inclusions, for the first time carried out in minerals of productive ore association let us speak of hypabyssal ore-forming conditions. Studied peculiarity of chemical composition of the extracted minerals show the complexity of minerals, what occurs to be the practical aspect of the investigations.
Keywords: admixtures elements, minerals, mineral associations, ore, deposit.

CLASSIFICATION OF THE CONTACT-METAMORPHOSED COALS AND APPRAISAL OF DIRECTIONS OF USE
The project of classification of contact-metamorphosed coals is developed. In capacity of classification indices for division of coals to marks there are accepted reflection index of vitrinite, yield of volatiles by weight, organic carbon content and specific electric resistivity. The methods and criteria for estimation of suitableness of the coals under examination for various directions of their use (production of filtering materials, adsorbents, carboreductors, and carbonic fillers, and also pigments, water-coal and coal-fuel oil suspensions) are developed.
Keywords: contact-metamorphosed coal, classification, methods and rational estimation suite, utilization.

PROSPECTIVE AREAS FOR HYDROCARBONS IN THE EAST EUROPEAN PLATFORM BASED ON REMOTE SENSING
Using the vegetation indexes of NDWI, NDVI and data of Landsat band 6, combined with structure-tectonic interpretation of Landsat images, has allowed establishing the location of prospective areas for hydrocarbons. The interpretation results contain new structure-tectonic data of the areas inside Belarus, Ukraine, and adjacent areas. The thrust faults with the south and west dips of thrust fault planes and fan-shaped folds as potential hydrocarbon structural traps were firstly determined by space images in this areas.
Keywords: remote sensing, satellite images interpretation, spectral anomalies, NDVI, NDWI, interpretive features, hydrocarbons, thrusts, fault zones.

PROBABLE CHANGES OF THE CONDITION OF WATER OBJECTS BY DEVELOPMENT OF THE BAKCHAR ORE UNIT (TOMSK REGION)
A method is proposed for estimating the permissible concentrations in wastewater potentially generated during the extraction of sedimentary iron ore and entering the rivers, depending on the upper limit of the confidence interval for the arithmetic mean concentrations of substances in groundwater drained by the sewage receivers. Additional specification of acceptable concentrations is carried out by analyzing the concentrations of substances in surface waters and bottom sediments. Approbation of the technique was carried out on the example of the experimental site of geological prospecting within the Bakchar iron ore cluster near the village of Bakchar (Tomsk Oblast).
Keywords: Bakcharsky iron ore junction, changes in the state of the water body, admissible impact.

MODERN METHODS OF RESERVES CALCULATION AND ECONOMIC-GEOLOGICAL EVALUATION OF DEPOSITS OF SOLID MINERALS
For reserves calculation and economic-geological evaluation of mineral deposits the most promising directions is the use of geological-mining information systems (GMIS) based on the data of block modeling. Considered the features of traditional resource estimation and block modeling; the necessity of comparing the data of calculations by alternative methods. Analyzed domestic experience of usage of block modeling in the development of the feasibility study and conducting calculation of reserves. The tasks of implementation GMIS in the practice of revaluation and development of deposits are specified. The attention is focused on the relevance of the development of domestic software products whose development requires financial, organizational and methodological support of state institutes and subsoil users.
Keywords: block modeling, databases, conditions, reserves calculation, geostatistics, geological and economic evaluation.
