(IGEM RAN) // alexandr@igem.ru ABOUT THE INDICATOR VALUE OF THE GOLDEN ROSSIPS OF THE NORTH OF GUYANA Present article attempts to examine the prospects of gold mining development in the Republic of Guyana on the basis of available published data and personal experience of one of the authors from conducting the expert prospecting on the placer deposits of North Guyana (Mathews Ridge area). The main Guyana’s gold deposits are located in greenstone belt, controlled by endocontacts of granitoid intrusions and are accompanied by numerous rich placers. These placers are the objects for small scale and artisanal mining and provide a significant proportion of the Guyana’s extracted gold. It is established that the studied area of the placer gold is confined to complications large granitoid intrusions and it’s satellites among the shale strata. Such placers serve as a direct indication of undiscovered bedrock gold deposits. Keywords: Guyana, Greenstone belt, gold, placer, quartz, bedrock deposits. Р. 3-7 |

(VIMS) // vims@df.ru MINERALOGICAL PECULIARITIES OF JEWELRY PYRITE FROM THE CRETACEOUS DEPOSITS OF ULYANOVSK REGION Gemological descriptions of spectro-pyrite – chuses of pyrite with bright many-coloured tarnish used in jewelry articles were studied for the first time. The chuses of spectro-pyrite are formed in marl biscuits collected from argillaceous deposits of Aption in Ulyanovsk region. The veinlets of spectro-pyrite, according to radiographical analysis consist from pyrite and dispersive calcite. Anhydrite and bassanite are fixed in them. It was established by carried out electronic-microscopic researches that facets of pyrite under oxidizing processes are exposed to intensive etching with formation of the superfine crusts and pellicles mainly oxides and hydroxides of iron. The colour of pyrites surface is connected with interference of light on pellicular formations and is defined by their mineral composition and thickness. Keywords: jewelry-decorative stones, pyrite, spectro-pyrite, Ulyanovsk region. Р. 7-12 |

The informatonal technology of modeling based on the factographic database on boreholes and 2-D digital models is described. The constructed 3-D models can be used for amplification of geological structure of coal-bearing strata and quantitative express-estimation of coal resources at allotting of licence plots.

(MAGE) // ivanov.gi@mage.ruFORECASTS AND OPENING OF OIL ON SPITSBERGENIn the early 1990 years, a number of oil and gas deposits were discovered in the wells on the bank of the Petunia bay in gypsum-carbonate deposits of Carboniferous age. These findings led to a review of the available geological information and a reassessment of the archipelago’s prospects in the oil and gas bearing respect. The possibility of new discoveries of hydrocarbon deposits on Russian sites is justified on it by available data on the structure of the section, the presence of reservoirs and fluids in it, the spread of oil and gas manifestations, and is confirmed by regional prerequisites and comparisons. The inconsistency of the traditional skeptic attitude to the probability of finding clusters of hydrocarbon raw materials here is shown, which is determined to a large extent by opportunistic considerations.
