(2001)New experiments on the effect of dissolved water on the ferric-ferrous ratio of silicic melts have been performed at 200 MPa, between 800°C and 1000°C and for fO2 between NNO-1.35 and NNO+6.6. Water-saturated conditions ...
-
(1998)The velocity of sound in liquid water has been measured as a function of temperature and pressure in the heated diamond-anvil high-pressure cell. The equation of state is determined at temperatures up to 200°C and pressures ...
-
(1998)As a major volatile in volcanic systems, water has a significant influence on the rheological properties of silicic magmas. This is especially so at minor water contents relevant to the emplacement of silicic lavas. To ...
-
(1998)Material recycling in subduction zones, including the generation and migration of aqueous fluids and melts, is key to understanding the origin of volcanism in subduction zones and is also important for understanding the ...
-
(1997)Addition of a simple evacuated collection device to nickel-tube pyrolysis bombs permits collection of the hydrogen gas produced during decomposition of water and other substances containing hydrogen. Tests using water ...
-
(2003)The kinetics of hydrogenation of dry synthetic forsterite single crystals was determined by performing experiments under hydrothermal conditions. The experiments were performed at 1.5 GPa, 1000 °C for 3 h in a piston-cylinder ...
-
(2001)Molecular water and hydroxyl groups are stable species in hydrous rhyolitic melts. To quantify the species concentrations we have used in situ IR spectroscopic measurements at 773-1073 K and 100-300 MPa in combination with ...
-
(1996)The influence of water on the dynamics of the oceanic upper mantle is re-evaluated based on recent experimental constraints on the solubility of water in mantle minerals and earlier experimental studies of olivine rheology. ...
-
(2000)Multi-anvil experiments have been conducted in the MgO-SiO2-H2O system at pressures of 15-24 GPa and temperatures of 1200-1600°C to investigate the partitioning of water between mantle phases. The water contents were ...
-
(2003)The water storage capacity of the major constituent of the lower mantle, Mg-perovskite, is a matter of debate. Here we report water solubility of Mg-perovskites with different compositions observed in peridotite and MORB ...

(2006)Представлены результаты исследования содержания тяжелых металлов в воде и донных отложениях (ДО) р. Амур на участках, подверженных влиянию стока крупных притоков: двух левобережных - Зеи и Буреи, водосборы которых расположены ...
