Abstract

Hydrothermal experiments on ion exchange reactions were carried out using synthetic and natural rhyolitic glasses and (Na, K)Cl aqueous solution at 200-300{degree}C and 1,000 bars. The rhyolitic glass did not crystallize during the reaction even under hydrothermal conditions, and it behaved as a Na-K ion exchanger. The Na-K ion exchange properties of the glass were strongly influenced by its thermal history. Quenched glass preferentially fixed K rather than Na, and glass obtained by slow cooling showed the opposite trend. The present experimental results show clearly that glass as well as minerals can control the composition of the coexisting aqueous solution in hydrothermal systems. The present results also suggest that the chemical composition of coastal thermal waters in Japan is controlled by the two-stage episode of reaction between acidic volcanic rocks and seawater.

Coastal submarine hydrothermal activity off northern Baja California

Journal Article Vidal, V; Vidal, F; Isaacs, J; ... - J. Geophys. Res.; (United States)

In situ observations of submarine hydrothermal activity have been conducted in Punta Banda. Baja Califronia, Mexico, approximately 400 m from the coast and at a seawater depth of 30 m. The hydrothermal activity occurs within the Agua Blanca Fault, a major transverse structure of Northern Baja California. Hot springwater samples have been collected and analyzed. Marked differences exist between the submarine hot springwater, local land hot springwaters, groundwater, and local seawater. SiO/sub 2/, HCO/sub 3/, Ca, K, Li, B, Ba, Rb, Fe, Mn, As, and Zn are enriched in the submarine hot springwater, while Cl, Na, So/sub 4//sup 2/, Mg,more »« less

Experimental study of chlorine behavior in hydrous silicic melts

Journal Article Metrich, N; Rutherford, M - Geochimica et Cosmochimica Acta; (United States)

Chlorine solubility in silicate melts has been investigated at 830-850 {plus minus} 5C and at pressures ranging from 50 to 200 MPa, using both natural (pantellerite, rhyolite, phonolite) and synthetic (SiO{sub 2}-Al{sub 2}O{sub 3}-K{sub 2}O-Na{sub 2}O) compositions and a stated H{sub 2}O-NaCl-KCl fluid phase near 4 molal. At 100 MPa, Cl contents in pantelleritic melts reach a solubility plateau at initial aqueous phase molality near 2. This plateau coincides with a large immiscibility gap between aqueous and chloride-rich fluids. With the coexisting Cl-saturated aqueous phase, Cl ranges from 2,720 {plus minus} 120 ppm in rhyolite to 8,960 {plus minus} 85more »« less

Experimental constraints on the partitioning of Cl between topaz rhyolite melt and H sub 2 O and H sub 2 O + CO sub 2 fluids: New implications for granitic differentiation and ore deposition

Journal Article Webster, J; Holloway, J - Geochimica et Cosmochimica Acta; (USA)

The partitioning of Cl between superliquidus melts of topaz rhyolite and fluids consisting of H{sub 2}O and H{sub 2}O + CO{sub 2} has been determined experimentally at pressures of 0.5 to 5 kbar and temperatures of 725{degree} to 950{degree}C with f{sub O{sub 2}} controlled near NNO. The major element and Cl contents of a starting material glass and the run product glasses were determined by electron microprobe. The concentration of Cl and the major elements in the fluid are calculated by mass balance. Cl partitions in favor of the fluid for all experimental run conditions. For natural abundances of Clmore »« less

Radium-thorium disequilibrium and zeolite-water ion exchange in a Yellowstone hydrothermal environment

Journal Article Sturchio, N; Bohlke, J; Binz, C - Geochimica et Cosmochimica Acta; (USA)

Whole rock samples of hydrothermally altered Biscuit Basin rhyolite from Yellowstone drill cores Y-7 and Y-8 were analyzed for {sup 226}Ra and {sup 230}Th to determine the extent of radioactive disequilibrium and its relation to the rates and mechanisms of element transport in the shallow portion of an active hydrothermal system. The ({sup 226}Ra/{sup 230}Th) activity ratios range from 0.73 to 1.46 and are generally correlated with Th-normalized Ba concentrations (Ba{sub N}). Compositions of clinoptilolite and mordenite in these samples are consistent with ion exchange equilibrium between zeolites and coexisting thermal waters. Average K{sup Ba}{sub d mineral-water} values are 1.0more »« less

Experimental Determination of Thermodynamic Properties of Ion-Exchange in Heulandite: Binary Ion-Exchange Experiments at 55 and 85 oC Involving Ca2+, Sr2+, Na+, and K+

Journal Article Fridriksson, T; Neuhoff, P; Viani, B; ... - American Journal of Science

Heulandite is a common rock-forming zeolite that exhibits wide solid solution of extra framework cations, presumably due to ready ion exchange with aqueous solutions. In order to provide a quantitative basis for interpreting and predicting the distribution of aqueous species between heulandite and aqueous solutions, ion exchange equilibrium between heulandite and aqueous solutions with respect to the binary cation pairs Ca{sup 2+} - K{sup +}, Ca{sup 2+} - Na{sup +}, K{sup +} - Na{sup +}, K{sup +} - Sr{sup 2+}, Na{sup +} - Sr{sup 2+}, and Ca{sup 2+} - Sr{sup 2+} was investigated.
