In situ X-ray di¡raction studies of dense hydrous magnesium silicates at mantle conditions
Lizardite was pressurized up to about 28 and 20 GPa and heated at 1310 ( þ 50) and 1100 ( þ 100)3C; antigorite was pressurized at about 25 and 22 GPa and heated at V10003C, with a Nd:YAG laser using the double-side laser heating technique. Samples were then examined in situ by energy dispersive synchrotron X-ray diffraction. Our results show that phase E, superhydrous phase B, and phase D are i...
متن کاملCrystal chemistry of silica - rich barium silicates II : Electron microscopy of barium silicates containing multiple chains
The phases containing multiple chains in the series Ba",+1[Si2mOsm+d those with triple (m = 3), quadruple (m = 4) and quintuple (m = 5) tetrahedral chains were investigated by high resolution transmission electron microscopy. The resulting images could be correlated with the structures. Variations of the chain multiplicity (m) within single crystals were observed as well as faults in the packin...
متن کاملHydrous Silicates and Water on Venus
We used thermochemical equilibrium calculations to predict Water vapor, present at 30–45 parts per million by volstabilities of pure rock-forming hydrous silicates on Venus’ ume (ppmv) in Venus’ subcloud atmosphere (Drossart surface as a function of elevation, atmospheric H2O and SO2 concentrations, and oxygen fugacity (fO2). About 50 different et al. 1993; Pollack et al. 1993; DeBergh et al. 1...
متن کاملHIGH-PRESSURE CRYSTAL CHEMISTRY AND AMORPHIZATION OF e-QUARTZ
Single-crystal X-ray diffraction experiments on e-quartz at pressures to 15 GPa reveal structural instabilities that result in its gradual transition to an amorphous state. With increasing pressure the average Si-O distance ( ~ 1.61 + 0.01/~) and S i O 4 tetrahedral volume (,,~2.14 ___ 0.02.~ 3) remain constant. Compression of e-quartz results from a dramatic decrease in Si-O-Si angle and corre...
متن کاملFar-infrared spectra of hydrous silicates at low temperatures
Context. Hydrous silicates occur in various cosmic environments, and are among the minerals with the most pronounced bands in the far infrared (FIR) spectral region. Given that Herschel and ALMA will open up new possibilities for astronomical FIR and sub-mm spectroscopy, data characterizing the dielectric properties of these materials at long wavelengths are desirable. Aims. We aimed at examini...
