(2003)Boron is an important micronutrient for plants, but high B levels in soils are often responsible for toxicity effects in plants. It is therefore important to understand reactions that may affect B availability in soils. ...
-
(1989)The study of granitoid plutons and their mapping is often hindered by the uniformity of their mineral and chemical compositions. Our investigation was done on the Kanzybinskiy granitoid pluton, near whose contacts are iron ...
-
(2002)Lower thrust sheets of the Scandinavian Caledonides derive from the margin of Baltica, which was imbricated during Early Palaeozoic closure of oceans formed during separation of the Baltica. Laurentia and Siberia cratons. ...
-
(1999)A suite of naturally-occurring carboxylic acids (acetic, oxalic, citric, benzoic, salicylic and phthalic) and their corresponding sodium salts were adsorbed onto a set of common mineral substrates (quartz, albite, illite, ...
-
(2000)The speciation and infrared spectra of aqueous solutions containing dissolved aluminum and picolinic acid (2-pyridinecarboxylic acid) were investigated using a combination of attenuated total reflection Fourier-transform ...
-
(2002)Bank filtration, either natural or induced through the river bed by pumping from a system of connected lateral or vertical wells, provides a means of obtaining public water supplies. The success of such schemes is dependent ...
-
(1988)The model of a medium with randomly distributed inhomogeneities is used to analyze the scattering properties of rocks on the basis of data on the fluctuations of the seismic wave field in them. But the capabilities of the ...
-
(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 ...
