-
(1995)Photoacoustic spectroscopy (PAS) yields information on complexation identical to that obtainable with conventional UV-visible absorption spectroscopy, but is up to three orders of magnitude more sensitive. The applicability ...
-
(2000)The concentration quotients for the following reactions with acetate have been measured at temperatures from 25°C to 225°C, at saturated water vapor pressure, and in 0.1 molal NaCl medium, using a potentiometric ...
-
(1996)The stability and stoichiometry of Nd(III) chloride complexes have been experimentally determined in the temperature range 40 to 300°C, P = Psat. The solubility of AgCl(s) was measured in solutions of fixed HCl + NaCl ...
-
(1995)Literature data on the thermodynamics of complexation of Zr with inorganic species, at 25°C, have been critically reviewed. The preponderance of published complexation constants deal with F− and OH− ions. Stability constants ...
-
(2003)The Arctic rift system includes the Mid-Arctic Gakkel Ridge, the Laptev Sea continental margin and the Moma rift. The Gakkel Ridge is the world''s slowest spreading mid-ocean ridge with spreading rates ranging from 1.2 ...
-
(2002)For a fractal curve, the measured perimeter length increases as the ruler length decreases. When the perimeter of a fractal curve is traced with a given ruler size, there are areas between the straight-line segments and ...
-
(2003)The problem of an 'Armorica microplate', detached from Gondwana and having had during part of the Palaeozoic an independent latitudinal evolution, is reconsidered in terms of a critical review of the palaeomagnetic data ...
-
(1997)Thermodynamic data for phases in the Fe-Si-O system have been assessed using experimental information on phase equilibria, electrochemical measurements of oxygen activity, calorimetry, and elastic property measurements. ...
-
(2001)It is accepted that during the Late Heavy Bombardment (LHB-4.2-3.8 Ga) in the Solar system, as preserved on the Moon, the terrestrial upper mantle-crust system was dominated by interactions between internal mantle processes ...
-
(2004)The paper describes the Au-PGE mineralization found in the coal-bearing depressions at the Pavlovsk brown coal deposit and at the depression borders. Precious metal mineralization occurs there at various levels of the ...
-
(2003)Data on lithology, trilobites, and ostracodes from the Azeri, Lasnamagi, and Uhaku horizons of the Ladoga structural-facies zone are discussed. Biostratigraphic subdivision based on asaphids (trilobites) has been conducted, ...
-
(2004)Compact analytical formulae are derived for particle motions of surface waves in a weakly anisotropic, flat-layered medium. Theory only incorporates coupling between fundamental mode Rayleigh and Love waves but comparison ...
-
(2004)The investigations involved geophysical, sedimentological, palynological, chemical and mineralogical studies, supported by field-based infrared spectrometry. The Baganuur Basin, Central Mongolia, is among the rift or ...
-
(2003)The main chain of SW–NE-striking Cenozoic half-grabens of the Baikal rift zone (BRZ) follows the frontal parts of Early Paleozoic thrusts, which have northwestern and northern vergency. Most of the large rift half-grabens ...
-
(1981)The development of the Baikal rift zone is an initial stage in the break-up of the Eurasian plate. In this zone the anomalous mantle is found under the crust. It is characterized by decreased seismic velocity, decreased ...
-
(2002)The Baikalide-Altaid, Transbaikal-Mongolian and North Pacific orogenic collages consist of several oroclinally bent magmatic arcs separated by accretionary complexes and ophiolitic sutures located between the major cratons. ...
-
(2001)The recently discovered Bamsk gold deposit is of a large scale. It is situated in the Amur oblast in Russia. The deposit is confined to a central type volcanoplutonic uplift of that formed during the early Cretaceous ...
-
(2002)Classification of barrier lakes of the Sayan-Baikal mountain region has been fulfilled on the base of such attributes as location and size, genesis (the origin of dam), age. According to the morphology barrier lakes may ...
-
(2001)The agreed boundary for the Lower Devonian basal Emsian stage Global Stratotype Section and Point (GSSP) is in a section at the Zinzil'ban Gorge of the Kitab State Geological Reserve, south-southeast of Samarkand, Uzbekistan, ...
