-
(1999)The conditions of the performed experiments were as follows. A three-component receiver was installed in a thermostatic pavilion of the seismological station "Novosibirsk". A vibrator (force amplitude 50-100 tons) was ...
-
(1989)The paper reports on a study to incorporate holographic methods into actual observation of hydrothermal crystals genesis. Real time visualization of the course of an experiment in an autoclave with optical windows was ...
-
(2005)Deformation assisted by transport in aqueous solutions is important for the rheology of earth materials, and models commonly used to describe deformation by dissolution-precipitation creep assume a steady state process in ...
-
(1989)Analysis of rock deformation is one of the central problems of theoretical and applied geology and geophysics. The stress states of rocks in nature are well modeled by experiments in high-pressure chambers on rock specimens ...
-
(2002)—We studied a set of 15 reference clays from The Clay Minerals Society (CMS) Source Clays repository. Our aim was to use them as reference materials in our version of the QUAX mineral database. The QUAX software (Quantitative ...
-
(2000)We have designed the first available experimental method capable to investigate the solubility of inert gases in H2O-CO2 bearing silicate melts in a large range of pressures. The method overcomes the difficulties imposed ...
-
(2000)A semi-theoretical model is proposed to predict partitioning of noble gases between any silicate liquid and a H2O-CO2 gas phase with noble gas as a minor component, in a large range of pressures (at least up to 300 MPa). ...
-
(2002)After a long history of development and improvement, recent transmission electron microscopes (TEMs) with various analytical functions have become important in material science and engineering. These functions include not ...
-
(2002)Due to the sun-synchronous GOCE orbit two polar regions with a radius of about 700 km cannot be observed. In this contribution effects of these data gaps are investigated using a regional recovery strategy. It consists ...
-
(1998)X-ray photoelectron spectroscopy (XPS), field emission scanning electron microscopy (FESEM), and open circuit potentials were used to compare the size, chemical state, and distribution of adsorbed and reduced gold from Au ...
-
(2004)We report the results of iodine-xenon analyses of irradiated halide grains extracted from the H-chondrite Monahans (1998) and compare them with those from Zag () to address the timing of aqueous processing on the H-chondrite ...
-
(2002)Initial 129I/127I values (I-Xe ages) have been obtained for individual mineralogically characterized chondrules and interchondrule matrix from the enstatite chondrites Qingzhen (EH3) and Kota Kota (EH3). In view of the ...
-
(1997)The limiting molar conductances (Λ0) and ion association constants of dilute (<0.01 mol . kg-1) aqueous potassium chloride and hydroxide solutions were determined by electrical conductance measurements from 200 to 600°C ...
-
(2004)The solar wind (SW) and the solar energetic particles (SEP, 1-50 MeV/n), being two distinguishable components of the solar corpuscular emanation, provide the direct clue to the processes in the corona and chromosphere. ...
-
(2000)A method has been developed for separating the Cr dissolved in natural water from matrix elements and determination of its stable isotope ratios using solid-source thermal-ionization mass spectrometry (TIMS). The separation ...
-
(2001)Sensitive high resolution ion micro-probe (SHRIMP) U–Pb analyses of zoned zircons were performed to constrain the age and geodynamic significance of the Kokchetav ultrahigh-pressure (UHP) metamorphic rocks, which recrystallized ...
-
(1995)Ion probe measurements offer the advantage of in situ determination of water content with a few micrometres spatial resolution. After a brief review of ion microprobe procedures used for the determination of water concentration ...
-
(1996)The lunar Mg-suite, which includes dunites, troctolites, and norites, makes up to 20-30% of the Moon's crust down to a depth of #60 km. The remainder is largely anorthosite. This report focuses on norites (which consist ...
