Clay Minerals in the MacAdams Sandstone, California: Implications for Substitution of H3O+ and H2O and Metastability of Illite
Electron microscopy Hydronium Illite Kaolinite Muscovite Rectorite
2011/12/1
Abstract: Clay minerals from the MacAdams Sandstone, Kettleman North Dome, California, have been studied by electron microscopy. The clay minerals fill pore space associated with fractured and breccia...
Metastability in Near-Surface Rocks of Minerals in the System Al2O3-SiO2-H2O
Aluminum hydroxide Dickite Gibbs free energy Halloysite Kaolinite Metastability Phase equilibria Pyrophyllite
2011/12/31
Gibbs free energies for phases in the system Al2O3-SiO2-H2O have been calculated from reversed experiments in order to correct earlier values and to calculate a phase diagram consistent with more rece...
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...
