State of weathering of some upland soils in the Alsea Basin, Oregon

Creator:: Rojanasoonthon, Santhad
Abstract:: Mineralogical analysis of 3 upland soil profiles over Tyee parent rock from the Alsea Basin Area, Oregon showed clear differences among the 4 soil series represented. Soils from the area of higher precipitation (over 80 inches, approximately) had no montmorillonite, lower base saturation and cation exchange capacity, but no lower...

Conditions of Al, Fe, and Mg interlayer formation in montmorillonite and vermiculite

Creator:: Carstea, Dumitru Dumitru
Abstract:: The influence of pH (titration method) and of salt concentration and drying (drying method) upon the formation of synthetic AI, Fe, and Mg interlayers in montmorillonite and vermiculite was investigated. Interlayer formation was evaluated by X-ray diffraction measurements of basal spacings using a natural chlorite for comparison. The titration method...
