(2003)The statistical analysis of compositional data based on logratios of parts is not suitable when zeros are present in a data set. Nevertheless, if there is interest in using this modeling approach, several strategies have ...
-
(1984)We have presented new data, connected with the use of oxygen isotope analysis. It was noted above that the age of epigenetic veins in the upper part of the cross section near the village of Seyakha are dated 9.3-8.7 thousand ...

(Федеральное государственное бюджетное учреждение науки Институт земной коры Сибирского отделения Российской академии наук, 2016)On 28 June 2014, debris flows brought large volumes of loose material into the Kyngarga river valley. The material was sourced from rock collapse and rock sliding on the valley slopes and delivered mainly to the river by ...
-
(2004)By using the elliptic function solution, the exact rotation solution of triaxial Earth is provided as motion of couple periods with an image decadal period longitudinally and Chandler wobble as transverse wave. To obtain ...
-
(2000)Although almost universally ignored, the effect of errors in the uranium decay-constants on U-Pb concordia-intercept ages (and Pb-Pb ages) are significant, and not equivalent to those of simple U-Pb ages. Equations are ...
-
(2003)This study presents carbon and oxygen stable isotope data obtained from high-resolution sampling (<500 μm) of the brachiopod terebratalia transversa from san juan islands (washington state, usa). aim this study is to unravel ...
-
(2002)X-ray microprobes are among the most important new analytical techniques to emerge from third generation synchrotron facilities. Here we show how X-ray fluorescence, diffraction, and absorption can be used in parallel to ...
-
(2013)We present a new dataset for whole-rock major, trace, isotopic, and phenocryst compositions indicating a genetic link between andesites of the Holocene eruptions of the Bezymianny stratovolcano (the Bezymianny stage), the ...
-
(2003)Within a geological massif in a stable geodynamical situation contacts on the grain boundaries in polycrystalline rocks at great depths are continuous and firm. The stress release of those rocks during drilling and excavation ...
-
(1997)Isotopically labeled n-hexadecane doped at the percent level in three crude oils is used to determine the intrinsic decomposition kinetics and mechanism of n-alkanes in petroleum. Adjacent 13C labels at the end of the ...
-
(1995)Rates and pathways of decomposition of three aliphatic amines (monomethyl, dimethyl, and trimethyl amine) and three amino acids (alanine, glutamic acid, and lysine) were investigated in anoxic salt marsh sediments dominated ...
-
(1997)This paper thoroughly describes the decomposition procedure, using the example of DE- COMPXR (Lanson 1990). The steps of the decomposition procedure are: 1) preliminary data processing; 2) decomposition; 3) validation of ...
-
(2004)Decomposition conditions of methane hydrates in sediments were measured during formation-decomposition cycles. As test sediments, we used silica sand, sandstone, and clays (kaoline and bentonite), which are typical natural ...
-
(2002)DRIFT (diffuse reflectance infrared Fourier-transform) spectroscopy was used to follow the early transformations that take place after the incorporation of organic materials in soil. Alfalfa (A), dried maize (DM), ...
-
(1998)High pressure, high temperature quench-type experiments were carried out on serpentine to pressures of 53 GPa and temperatures between 800-1800°C. X-ray analyses show that recovered phase assemblages varied considerably ...
-
(2001)Carbon mineralization of fresh and aged diatoms (Skeletonema costatum) and barley hay (Hordeum vulgare) was followed for 23 to 35 d in sandy and silty sediment. By the use of a thin-layer flow-through technique, it was ...
-
(2003)An experimental study of H2O exsolution, bubble growth and microlite crystallisation during ascent (decompression) of silicic magmas in the volcanic conduit is presented. Isobaric and decompression experiments were performed ...
-
(1990)There exists a group of igneous rocks, generated in an environment of intense fluid activity, from specific fluid - silicate systems in which the concentrations of fluids are comparable to those of the petrogenic oxides. ...
