-
(2002)The Ulleung Basin in the East Sea (Sea of Japan) has experienced back-arc opening in the Miocene and partial closure since the middle Miocene. Uplift along the southern basin margin, caused by the back-arc closure, resulted ...
-
(1996)Systematic investigations (electron- and ion-microprobe, and X-ray structure-refinement) of pyroxenes and amphiboles close to a cm-wide hornblendite vein have been carried out on a composite peridotite sample from the Lherz ...
-
(1986)Wood & Graham (1986) suggest that fluid: rock ratios of Ferry (1984) were over-estimated because the temperature of the biotite isograd, inferred from biotite-garnet and calcite-dolomite geothermometry, was underestimated ...
-
(2000)A semitheoretical expression for partial molar volumes at infinite dilution of aqueous nonelectrolyte solutes has been developed employing the collection of properties from fluctuation solution theory for use over wide ...
-
(2000)The volumetric equation proposed previously (Plyasunov et al., 2000), for estimating the infinite dilution Gibbs energy of hydration of volatile nonelectrolytes at temperatures exceeding the critical temperature of pure ...
-
(2001)A new taxon Freyantha sibirica gen. et sp. nov. is erected for a delicate racemose inflorescence from the Cenomanian of the Tchulymo-Yenisey Basin, West Siberia. The inflorescence bears male flowers of partly connate stamens ...
-
(1997)The α-amino and α-hydroxy acids found in the Murchison carbonaceous chondrite are deuterium enriched. These compounds are thought to have originated from common deuterium enriched carbonyl precursors, by way of a Strecker ...
-
(1997)Hydrothermal convection in the upper oceanic crust has been inferred to be a globally common and important process. Under the simplest conditions of planar boundaries, lateral dimensions of convection cells provide a strong ...
-
(2002)Flux-grown Fe3+-bearing spinel s.s.–hercynite solid-solution crystals, (Mg1-y Fe2+y )Al2O4 (0 < y≤ 1), have been investigated by means of electron microprobe technique and Mössbauer and electronic spectroscopy. Obtained ...
-
(2004)This paper presents the results of theoretical and experimental investigations of the system rubidium feldspar-quartz-water at a pressure of 1 kbar. It was found that rubidium leucite (RbAlSi2O6) rather than feldspar is ...
-
(Федеральное государственное бюджетное учреждение науки Геофизический центр Российской академии наук, 2015)The regularities of the global intraplate volcanism of the Earth are explained by the mantle plumes originating at the heads and margins of two piles of dense material of the hot and relatively heavy $D''$~layer at the ...
-
(2001)Source time functions of 255 moderate to great earthquakes obtained from inversions of teleseismic body waves by Tanioka and Ruff [1997] and coworkers were compared in a systematic way. They were scaled to remove the effect ...
-
(2001)Process of crushing the ore with the use of explosion has been considered. Laboratory and natural investigations of the process have been performed. Influence of vertical cylindrical explosive charge on degree of crushing ...
-
(2003)The influence of F content on the formation and stability of Al-rich phlogopite has been investigated. Samples with varying OH/F-ratios and nominal gel compositions of K(Mg3-xAlx)(Al1+xSi3-xO1O)(OH)y (F)2-Y (0-0 less than ...
-
(2003)The influence of F substitution on the local structure of Al in the tetrahedral and octahedral sheets of synthetic Al-rich phlogopite samples with nominal gel compositions of K(Mg3-xAlx)[Al1+xSi3-xO10] (OH)y(F)2-y between ...
-
(2006)A multinuclear solid-state NMR investigation of the structure of the amorphous alteration products (so called gels) that form during the aqueous alteration of silicate glasses is reported. The studied glass compositions ...
-
(2004)The influence of grinding on colour and particle-size properties of talc and smectite from a white bentonite were studied and compared with a fine-grained calcite from a chalk. Grinding decreased the grain size of all three ...
-
(1996)The most important solution chemical controls on weathering rates are the pH and concentration of chelating ligands. Here, data from controlled laboratory experiments are used to highlight pertinent differences between ...
-
(2001)Influence of molecularly sorbed reagents on formation of flotation complex of particle-bubble has been investigated. Results of the investigations have shown that presence of the reagents leads to increase in speed of fluid ...
-
(2001)The paper considers the influence of deep and subsurface heterogeneities on the parameters of seismic signals from earthquakes. Evaluation of degree of influence of the above heterogeneities on the calculated parameters ...
