This paper was prepared by liquid phase deposition of quartz sand load nanometer titanium dioxide film, in which quartz sand as the carrier, and to Fe3+,Zn2+ as doping on the membrane was modified. Th...
The ultra-structures of Zaocys dhumnades’s ventral scale surface were observed by the AFM (Atomic Force Microscopy), at the same time, the frictional properties between ventral scale and the stainless...
Experimental study of the permeability of clays from the potential sites for acid effluent storage.
Previous investigators have shown that, at high pressure, Re is a good capsule material and that Fe loss to Re under these conditions is minimal (e.g., Herzberg and Zhang 1997). We present here the ...
Abstract: Despite substantial scientific research efforts, accurate determination of the petrophysical effects of clay minerals on reservoir sands remains problematic. Diagenetic clays such as smectit...
The intergranular fluid involved in solid-solid reactions is tacitly assumed to be a melt or a (C-O-H-S-Cl-F)-bearing phase. We have studied the system olivine 1metal using dif-fusion couple experimen...
The Gibbs free energy (DG ) of the reaction kaolinite £dickite was generated from 0(1) solubility measurements of natural kaolinite and dickite performed in acid solutions at temperatures ranging from...
Startling results were obtained in kinetic experiments that varied the initial heating history of the mineral reaction: 1 dolomite 1 2 quartz → 1 diopside 1 2CO2. The exper-iments were carried out at ...
The stability field of MgMgAl-pumpellyite, Mg5Al5SiO21(OH)7, was determined in the system MgO-Al2O3-SiO2-H2O in reversal experiments at pressures between 34 and 100 kbar and temperatures in the range ...

Wehave measured the pressures of decrepitation of vesicles in synthetic glasses of feldspar compositions (NaAlSi30g-KAlSi30g). Vesicles filled withXedo not decrepitate at internal pressures of 160 MPa...
Experiments on tonalite and granodiorite wereperformed at conditions ranging from 2.1 to 18kbar and 550 to 850°C to establish the magmatic stability field ofepidote as a function ofP, T,and f02. Atwat...
