Nature of interlayer material in silicate clays of selected Oregon soils

Creator:: Singleton, P. C.
Abstract:: A study was conducted to investigate the nature of hydroxy interlayers in the chlorite-like intergrade clays of three Oregon soils with respect to kind, amount, stability, and conditions of formation. The clays of the Hembre, Wren, and Lookout soils, selected to represent weathering products originating from basaltic materials under humid,...

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...

Abstract:: A study was conducted to determine the mineralogy and chemical properties of "Ando-like" western Oregon soils. The samples were collected from 13 sites which formed mainly from basaltic rocks, a contact metamorphic rock, sedimentary rocks, and alluvium derived from sedimentary rock and from volcanic rock. All samples contained small amounts...
