(2000)Viscosity of melt at high pressure provides an important clue to understanding the dynamics of magmas in the Earth's deep interior. We measured viscosity of the albite melt to 7 GPa at 2000 K by the falling sphere method ...
-
(2001)The viscosity of emulsion and suspensions in the presence of two types of nano-size particles that, have different affinity for oil, have been investigated. It has been found out that both oil-solid suspensions and ...
-
(2001)The temperature dependence of viscosity was investigated at 1 atm and at temperatures near the glass transition in the dry Qz-Ab-Or system [SiO2 (Qz)-NaAlSi3O8 (Ab)-KAlSi3O8 (Or)]. This system is particularly difficult for ...
-
(2003)Anisotropy of viscosity in rocks has a significant effect on the development of geological structures, as demonstrated in several theoretical and analogue model studies. This paper develops the results of a self-consistent ...
-
(2005)We develop a steady-state fluid-mechanical analysis describing the effect of strain partitioning on viscous energy dissipation. As observed in experimental studies of shear deformation of partially molten rocks, strain ...
-
(1999)The detection of several ultralow velocity zones (ULVZ) on the core-mantle boundary (CMB) together with the recent estimates of the lower-mantle solidus would suggest that some sort of melting may occur inside the upwellings ...
-
(2022)A large amount of continuously increasing textual geoscience data is stored and not fully utilized. Text mining enables the discovery and analysis of valuable information,and presents valuable insights hidden in geological ...
-
(2002)High spatial and temporal resolution measurements of suspended sand concentration (c ) over vortex ripples were collected with a three-transducer acoustic backscatter sensor (ABS) array, under irregular `natural' waves in ...
-
(2003)The aim of the study was to determine optical properties of vitrinite, subjected to temperatures within the range of 400-1200 °C for durations of 1-7 h, in an argon atmosphere. The samples of vitrinite concentrate (Vt ...
-
(1999)Repeated Very Long Baseline Interferometry, VLBI, measurements exhibitautocorrelation before the baseline rates are estimated and removed from the data.Autocorrelations reduce markedly once the baseline rates are estimated. ...
-
(PANGAEA, 2010-05-04)Vodyanitskii mud volcano is located at a depth of about 2070 m in the Sorokin Trough, Black sea. It is a 500-m wide and 20-m high cone surrounded by a depression, which is typical of many mud volcanoes in the Black Sea. ...
-
(2007)Volatile element, major and trace element compositions were measured in glass inclusions in olivine from samples across the Kamchatka arc. Glasses were analyzed in reheated melt inclusions by electron microprobe for major ...
-
(2000)The phase diagram for lherzolite-CO2-H2O provides a framework for interpreting the distribution of phase assemblages in the upper mantle with various thermal structures, in different tectonic settings. Experiments show ...
-
(2005)A compendium of diffusion measurements and their Arrhenius equations for water, carbon dioxide, sulfur, fluorine, and chlorine in silicate melts similar in composition to natural igneous rocks is presented. Water diffusion ...
-
(2003)The abundances of the elements H, C, N, Ne, primordial Ar, Cl, Br, Kr, I and Xe, in the atmo-hydrosphere, continental crust and MORB-source mantle (termed the outer Earth reservoirs (OER)) are examined and compared with ...
-
(1993)The platinum-group elements (PGE) are appreciably volatile in dry systems in the presence of both Cl and S at 1000°C. The present experiments were conducted in sealed silica-glass tubes, with charges of either pure metals ...
-
(1997)Amphibole (n = 11), mica (n = 16), apatite (n = 9) and clinopyroxene (n = 19) from mantle xenoliths in alkali basalts from Siberia, Mongolia and Spitsbergen were analysed for Rb, Sr, Ba, Y, Zr, Nb, Th, U, Pb, La, Ce by ...
-
(2003)We report noble gas and nitrogen analyses of newly discovered SNC meteorites, one nakhlite (NWA817) and four shergottites (NWA480, NWA856, NWA1068, and SaU 005). The K–Ar age (1.3 Ga) as well as the cosmic-ray exposure ...
