Clay mineralogy in relation to landscape instability in the coast range of Oregon

Creator:

Istok, J. D.

Abstract:

The mineralogy of soils involved in mass movement in Oregon's coast range was examined to determine relationships between clay mineralogy and landscape instability. The objectives were: 1) to determine what kind of materials constitute the less than 2μ fraction of soils involved in different categories of mass movement, and 2)...

Effects of clay-water interactions on water retention in porous media

Creator:

Lenhard, Robert J. (Robert James)

Abstract:

Capillary pressure-saturation data obtained for unconsolidated porous media with different liquids are examined to investigate the effects of clay-liquid interactions on liquid retention. Liquid retention functions are assumed to reflect the effective pore-size distributions. The hydraulic variables, capillary pressure and saturation, are transformed to account for changes in liquid retention...

Relationships of clay mineralogy to landscape stability in Western Oregon

Creator:

Taskey, Ronald D. (Ronald David), 1944-

Abstract:

Soil erosion by mass wasting is the major problem on forest lands of the Pacific Northwest, The clay fractions of soils from a large number of sites in Oregon's Western Cascades were characterized in order to determine the relationships of various clay materials to mass movements. Each site was either...

Soil solution chemistry, profile development, and mineral authigenesis in several western Oregon soils

Creator:

Glasmann, Joseph Reed

Abstract:

Clay mineral genesis was studied in soils representative of several different geomorphic surfaces in western Oregon, ranging in age from Pliocene-early Pleistocene to late Pleistocene. Soil solution studies, clay mineralogy, and soil raicromorphology were employed to provide evidence of clay mineral synthesis and interpret soil genesis. Soils at each study...
