The results of spectral-correlation analysis of gravity and magnetic data sheet L-53-VI (fields Dg and DТ scale 1:200 000), which allowed to reproduce (outline) in the values of the densities (g/cm3) and conventional units of magnetization of rocks potentially ore-bearing volume of the subsoil in the area of sheet L-53-VI and to allocate, within its limits, the situation close to their geological and geophysical characteristics to the reference ore areas and knots of Primorsky Krai (East, Lermontov RU). Within the limits of sheet L-53-VI the prospecting sites of the grade “ore node-field”, perspective on revealing of skarn-sheelite-sulfide deposits with rich ores (from 0,3% to 5,5-7,06%, WO3 and more) are designated and contoured.

(Institute of mineralogy of the Ural division of RAS) // ryzhkov@mail.ru GEOLOGY AND PETROGRAPHY OF DEPOSITS OF VEIN QUARTZ «PESCHANOE» (SOUTH URAL) The article presents actual data on the geological position of quartz veins formed during the process of filling open cracks in the granite massif. Change the granites, developed places in the mylonites and blastomylonites and the presence of quartz grains distinct traces of brittle and plastic deformations indicate cataclastic metamorphism after the formation of quartz veins. The study of quartz aggregates and investigation of gas-fluid inclusions in grains of white, milky white and grey quartz allowed us to determine the temperature range of eutectic at cryothermometric data and the maximum temperature of homogenization 356 ºС and minimum 241 ºС–257 ºС. These data indicate that the hydrothermal formation of quartz veins at the temperature of 300 ºC–360 ºС. Recrystallization of quartz in the process of the volumetric strain occurred at temperatures 200 ºС–270 ºС. Keywords: quartz, granite, blastomylonits, gas-fluid inclusions, the temperature of homogenization. Р. 18-24 |

(VSEGEI) // Sergey_Sokolov@vsegei.ru METHODS OF QUANTITATIVE RESOURCE ASSESSMENT ACCORDING TO THE GEOCHEMICAL DATA FROM POTENTIALLY ORE AREAS AT THE STAGE OF REGIONAL STUDY OF THE SUBSOIL Methods of forecast resources assessment reflected in the current normative methodological documents are considered in terms of the critical approach. The method proposed by the authors, unlike the one, taken from the instruction, provides for the assessment of resources for higher-ranks ore objects, taking into account the share of commercial metal as well as on the basis of the theoretically grounded and practically widely tested system of parameters selecting as well as selecting of characteristics for anomalies and predicted mineralization. Resource assessments obtained with use of the method proposed are much more adequate to the prospecting and exploration data than the one, taken from the instruction.

With this purpose g-spectrometric method of analysis were used. It is shown that very high radioactivity of bentonite clay is associated with a high content of 40K, 226Ra, 232Th in its composition and is caused by active exogenous and endogenous migration processes. Keywords: radioactiviti, radionuclide, migration, diffuzion, sorption, sedimentary rosk, bentonitic clay. Р. 38-41 |

The model considers streams of different orders, closed local relief depressions, catchment basins and their morphometric and hydrological indices. The proposed methods allow to identify zones of increased moisture, which is accompanied by increased infiltration of surface water into the rocks, that leads to the development of suffusion and karst processes. Keywords: geomorphology, surface runoff, suffusion, karst, deposit, safety. Р. 42-49 |

It examines the state of production, export-import of ferroalloys and its mineral resource base. The heavy deficit of reserves of rich manganese and chromium ores covered by expensive imports is shown. Recommendations on import substitution of scarce raw materials through development and implementation of effective technologies of poor and persistent ores processing at the previously explored deposits, and also revealing and development of new economically acceptable deposits are offered.
