Redox conditions in piston-cylinder apparatus: The different behavior of boron nitride and unfired pyrophyllite assemblies
Redox conditions piston-cylinder apparatus different behavior boron nitride unfired pyrophyllite assemblies
2012/4/5
Piston-cylinder experiments with C-H-O fluids in equilibrium with graphite as redox
sensor were performed at 900!a and 10 kbar. With this technique, it is possible to inves-

The Surface Coulomb Energy and Proton Coulomb Potentials of Pyrophyllite {010}, {110}, {100}, and {130} Edges
Edge structure Electrostatic potential Lattice sum Pyrophyllite
2011/12/29
This paper describes structural models of four pyrophyllite edge faces: {010}, {110}, {100}, and {130}. Water molecules chemisorbed to Lewis acid sites stabilize edge faces both crystallochemically an...
Electrostatic Potential at the Basal (001) Surface of Talc and Pyrophyllite as Related to Tetrahedral Sheet Distortions
Basal oxygen sheet Electrostatic potential Pyrophyllite Talc Tetrahedral sheet distortion
2012/1/5
Maps of the electrostatic potentials at the basal plane of talc and pyrophyllite, computed using a two-dimensional Ewald lattice-sum, reveal the effects caused by structural distortion of the phyllosi...
Transmission Electron Microscopic Study of Coexisting Pyrophyllite and Muscovite: Direct Evidence for the Metastability of Illite
Analytical electron microscopy Illite Muscovite Pyrophyllite Solid solution Thermodynamic stability Transmission electron microscopy
2012/1/4
Transmission electron microscopy has been used to characterize coexisting pyrophyllite and muscovite in low-grade metamorphosed pelites from Witwatersrand and northeastern Pennsylvania. The Witwatersr...
Solubility Diagrams for Explaining Zone Sequences in Bauxite, Kaolin and Pyrophyllite-Diaspore Deposits
Solubility Diagrams Zone Sequences Pyrophyllite-Diaspore Deposits
2012/2/13
Solubility diagrams defined by log [Al3+] and log [H4SiO4] are given for hydrous alumina or aluminum silicate minerals which appear in bauxite, kaolin and pyrophyllite-diapore deposits. They are const...
The Origin of Pyrophyllite Rectorite in Shales of North Central Utah
Origin Pyrophyllite Rectorite Shales North Central Utah
2012/2/20
Pyrophyllite is widespread in pelitic rocks of the Manning Canyon Shale in north central Utah, and the association of this mineral with other clay minerals, especially rectorite is related to the orig...
