(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 ...

(2010)Золото-серебряное оруденение континентальной тихоокеанской окраины Северо-Востока Азии контролируется разновозрастными вулканогенными поясами, наложенными на кратонные, пассивных континентальных окраин, островодужные и ...
-
(2006)В статье обобщены результаты тектоно-металлогенических, геолого-структурных, минералогических, изотопных и термобарогеохимических исследований, проведенных в пределах месторождения Алшар и его районе. Полученные данные ...

(Федеральное государственное унитарное предприятие «Центральный научно-исследовательский геологоразведочный институт цветных и благородных металлов», 2020)Au-Pd-Cu-Se-U минерализация рудопроявления Светлое (Центральная Карелия) формировалась близповерхностно в условиях привноса селена, меди, свинца, благородных металлов, урана и интенсивного окисления ~1500 млн лет назад. ...
-
(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, ...

Authigenic carbonate and barite mineralization in sediments of the Deryugin Basin (Sea of Okhotsk). (PANGAEA, 2000-06-06)Results of studies of mineralogy, geochemistry, and isotope parameters (d13C, d34S, d180, and 87Sr/86Sr) of carbonates and barites from sediments of the Deryugin Basin in the Sea of Okhotsk are presented. Diagenetic nature ...
-
(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. ...
