Spectroscopic Approach for Investigating the Status and Mobility of Ti in Kaolinitic Materials
Diffuse reflectance spectroscopy Kaolins Ti-mobility Ti-status
2011/12/28
The form under which Ti occurs in kaolinitic materials from various environments has been investigated using second derivative diffuse reflectance spectroscopy. The position of the absorption edge may...
Goyazite in Kaolinitic Altered Tuff Beds of Cretaceous Age Near Denver, Colorado
Diagenesis Goyazite Kaolinite Phosphorus Volcanic ash
2012/2/7
A hydrated alumino-phosphate mineral was identified in thin, kaolinitic clay beds of the Cretaceous Dakota Group and the overlying Mowry Shale in the Dakota hogback west of Denver, Colorado. It occurs...
Electrical Conductivity and the Surface Characteristics of Kaolinitic Clays and Clay-Humic Acid Complexes
Electrical conductivity Electrophoresis Humic acid Kaolinite Surface properties
2012/2/8
The conductivites of the Na and H ion-exchanged forms of kaolinitic clay rejects from sand-washing operations, both purified and as found naturally as a complex with soil organic matter, were examined...
Surface Characteristics of Kaolinitic Clays and Clay-Humic Acid Complexes by Potentiometric and Conductometric Titrations
Conductometric titration Humic acid Kaolinite Potentiometric titration Surface properties
2012/2/8
Acid and non-acid forms of kaolinite clays were found by potentiometric and conductometric titrations to possess a weak acid species, the concentration of which was increased by acidic preparation con...
The System SiO2-AlOOH-Fe2O3-H2O and the Kaolinitic Stage of the Goethite Facies
SiO2-AlOOH-Fe2O3-H2O Kaolinitic Stage Goethite Facies
2012/2/15
A 25°C, 1 atm total pressure phase diagram for the system SiO2-AlOOH-Fe2O3-H2O, is determined using the Phase Rule and Shreinemaker's technique as in Chesworth (1974). The water-present assemblages so...
