(2002)In this paper, we address the irregular behaviour and geometry of the gas hydrate stability zone (HSZ) inferred from reflection seismic data in relation to heat-flow measurements. The study area lies in the hanging wall ...
-
(2006)В статье обобщены результаты тектоно-металлогенических, геолого-структурных, минералогических, изотопных и термобарогеохимических исследований, проведенных в пределах месторождения Алшар и его районе. Полученные данные ...
-
(2004)Приводятся данные о Au-PGE-минерализации, обнаруженной в угленосных впадинах Павловского буроугольного месторождения и на их обрамлении. Показано, что благороднометальная минерализация развивается здесь на разных уровнях ...
-
(2001)The application of new capabilities of audiomagnetotelluric sounding (AMTS) is explained using the example of the Nagolny ore area (the Bobrikovo gold and polymetallic deposit). Using for the first time the newly developed ...
-
(1981)Riphean and Palaeozoic linear graben-like platform depressions — aulacogens —jointly with linear swell uplifts in a platform cover, intraplatform folded zones and Meso-Cenozoic epi-platform rift zones are different ...
-
(1988)The gold-silver ores of eastern Yakutia abound with 'mustard' gold. In the upper ore levels that material consists of supergene antimony oxides. At greater depths it consists of hypogene antimony oxides and stibnite. It ...
-
(1997)About 10,000 years ago, at the Pleistocene-Holocene border, some important events occurred: the glaciation stopped abruptly; the sea level elevated, and quick (for 20-50 years) climatic and ecological changes took place, ...
-
(2004)Oceanic authigenic carbonates are classified according to the origin of carbonate carbon source using a complex methodology that includes methods of sedimentary petrography, mineralogy, isotope geochemistry, and microbiology. ...
-
(2002)The diagenetic evolution of kaolin and illitic minerals in sandstones is described here. The structural characterization of these minerals, the possible reaction pathways leading to their crystallization, and the origin ...
-
(1997)Formation of authigenic sulfides and carbonates in Holocene 14C-dated sediments is interpreted based on analyses of cations, FeS-S, FeS2-S, Corg and sulfur isotopes. Mineral distribution was studied in thin sections and ...
-
(2003)We report the development of a new analytical system allowing the fully automated measurement of isotopic ratios in micrometer-sized particles by secondary ion mass spectrometry (SIMS) in a Cameca ims-6f ion microprobe. ...
-
(1987)The basic problem of modern geolectric science is the development of methods for interpreting the data of electromagnetic investigations in areas with complex laterally nonuniform structure of the geoelectric section. A ...
-
(2002)In order to provide a basis for short-term decision-making in the forecasting and monitoring of volcanic activity, we developed an entirely automated system of data acquisition and reduction for magnetic data. The system ...
-
(2001)Parameters of hydrologic models often are not exactly known and therefore have to be determined by calibration. A manual calibration depends on the subjective assessment of the modeler and can be very time-consuming though. ...
-
(2001)Simulated annealing simulation (SAS) is a flexible tool for generating stochastic simulations conditioned to data at various scales and precision. However, a number of important drawbacks exists: (1) SAS requires considerable ...
-
(1989)Pyrite is one of the principal concentrators of gold in most types of commercial ores. There is an interest in studying the mechanism by which gold is concentrated and the forms in which it occurs in pyrite. The authors ...
-
(1998)The structure of the avacha Depression, covered by a thick sequence of volcanic rocks, volcano-sedimentary deposits, and loose Quaternary sediments of varying origins, was reconstructed using the results of a geological ...
-
(1988)The Siberian craton abounds with traps of different facies, and may be regarded in this respect as a standard. Permian-Triassic traps are most common here, so we primarily use them to characterize the volcanisms of the ...
