  • A qualitative and quantitative characterization of porosity in volcanic ash

    Creator:
    Doak, William Herman, 1941-
    Abstract:
    Soils developed on volcanic ash exhibit several unique properties not commonly observed in soils formed on other geologic material. Low thermal conductivities, low volumetric heat capacities, slow transport phenomena, excess macro-drainage and development of unique suites of clay minerals are some properties thought to be directly related to the vesicular...

  • Cation retention and solute transport related to porosity of pumiceous soils

    Creator:
    Doak, William Herman, 1941-
    Abstract:
    Previous studies of pumiceous soils in Oregon indicated that their physical and chemical properties were strongly related to the porous nature of the pumice matrix. Soils developed on air-fall pumice from the eruption of Mt. Mazama (Crater Lake, Oregon) had low thermal conductivities and low volumetric heat capacities. Values for...
