Genesis and Morphology of Iron Sulfides in Gray Kaolins
Autor: Joe B. Dixon, G. Norman White, R. M. Weaver, A. C. Kunkle
Publikováno v: Clays and Clay Minerals. 39:70-76
Many of the presently oxidized Georgia kaolins probably existed originally in the reduced (gray) state. For that reason, the distribution of iron sulfides in presently gray kaolins may elucidate features observed in oxidized kaolins. An understanding

Surface Stability of Siderite Under Acidic Atmosphere: an Atomic Force Microscopy Study
Autor: R. M. Weaver, David E. Grandstaff, G.H. Myer
Publikováno v: MRS Proceedings. 453
The reactivity of siderite (FeCO3) was investigated under ambient atmosphere and acidic aerosols using an atomic force microscope (AFM). Scans of freshly cleaved siderite crystals showed a relatively irregular microtopography, consisting of high-dens

CHARACTERISTICS OF THE MINERAL CONSTITUENTS OF SOME ALBIC AND SPODIC HORIZONS AS RELATED TO THEIR CHARGE PROPERTIES
Autor: A. D’Avignon, M. R. Laverdière, R. M. Weaver
Publikováno v: Canadian Journal of Soil Science. 57:349-359
Some physical, chemical and mineralogical properties of five albic and six spodic horizons were studied in an attempt to relate their composition to their charge properties. The samples investigated contained less than 3% clay and had specific surfac

Clay Mineral Stability as Related to Activities of Aluminium, Silicon, and Magnesium in Matrix Solution of Montmorillonite-Containing Soils
Autor: Marion L. Jackson, R. M. Weaver, J. K. Syers
Publikováno v: Clays and Clay Minerals. 24:246-252
The influence of geomorphological site characteristics on soil clay mineral stability of montmorillonite-containing horizons of a southern Wisconsin soil catena was interpreted in terms of the solute activity function values of pSi(OH)4, pH-1/2pMg2+
