(EMG LLC «Gloom-river»)// ugrjum@list.ru THE COMPARATIVE RESULT OF TWO METHODS OF THE STOCK COUNTING OF AURIFEROUS SAND ON THE EXAMPLE OF AMUR REGIONS DEPOSITS The method of the metal’s stock counting in auriferous sand’s deposits is proposed, it is based on the mechanism of propability-statistical influence of every geological assay selection on the counting result. The essential change of the stock counting in comparison with the existent method is not observed, so by the metal’s stock counting all assays selection take part without the changes of their absolute meaning. Key words: assay, very high assay, stock counting, influence coefficients. Р. 9-12 |

(Institute of Geology Karelian Research Center Russian Academy of Science) // chthonian@yandex.ru STRUCTURING OF A ROCK MASSIF OF DIMENSION STONE DEPOSITS ON THE BASIS OF INTEGRATED MODELLING A method for improving the evaluation quality of raw materials at dimension stone deposits, based on 3D modelling of a rock massif is discussed. The results of geological-geophysical studies conducted in a gabbrodolerite block-producing quarry «Drugoreckoe-3» (South Karelia) are presented as an example of the method proposed. The data obtained are used to support the integrated approach as a factor which increases reliability of evaluation block sizes. Furthermore, some characteristics of 3D electrical resistivity tomography used to determine fracturing are analyzed and the correlation level of geological and geophysical information is assessed. Key words: dimension stone, 3D model, structuring, fracturing, block sizes, 3D ERI. Р. 22-27 |

(Saratov national research university) korob@info.sgu.ru SECONDARY ALBITES IN A TERRIGENOUS RESERVOIRS FROM WEST SIBERIA AS INDICATORS OF OIL AND GAS PROMISING TERRITORY Corrosion and regeneration types of plagioclase albitization have been determined in a terrigenous complex of productive reservoirs within the cover; this reflects two settings of tectonic-hydrothermal activation in a riftogenic sedimentary basin. Under the pulsating stress conditions (geodynamic anomalies), all plagioclases experience corrosion and, consequently, deanorthitization, with formation of authigenic albite foraminated crystals. In relatively quiescent tectonic settings, regeneration albite develops, generally over the fragments of terrigenous albite (albite-oligoclase). The process of plagioclase deanorthitization is accounted for by the internal resources of the mineral elements, while origination of regeneration (vein) albite requires Na, Al, and Si inflow from the outside. To a considerable extent, they may be supplied with the brines arriving from the Paleozoic basement of the West Siberian Plate and actively involved in hydrothermal mineral formation. Key words: corrosion and regeneration albite, brines, reservoirs, hydrocarbons, hydrothermal springs, tectonic activity. Р. 27-32 |

The influence of various noise was estimated, had chosen an optimal processing parameters, that reduce ambiguity of geological interpretation data of electroresistivity tomography method. The dependence of inversion effectiveness from station interval, quality of initial data, overlap of geoelectrical section of direct and reversal installations was confirmed. Studying of ore – hosting structures of Kelyano-Irokindinskoy structural-formation zone were shown that in permafrost and Alpine terrain conditions it is important to count a confounding factor. It could allow increasing effectiveness and detail of geological interpretation data by electroresistivity tomography method.
