Palaeoenvironmental Characterisation Using Clay Mineralogy: A Case Study of the Heelbo hillslope deposit, Free State Province and the Diepdrift hillslope deposit, Limpopo Province, South Africa.
Clay minerals of Site 397 have mainly a detrital origin, including smectite, attapulgite (= palygorskite), and sepiolite. There is no quantitatively marked influence of volcanism on the clay assemblag...
In this study, based on topographic maps, satellite images and conducted several field visits, ten pedons studied in the area and for further study four representative pedons selected which occurring ...
Knowledge of soil types and their properties is highly important in determining constraints and potential as well as better utilization of soils. Clay minerals are important fractions of the soil soli...
The clay mineral content of the Oligocene sediments in the Linxia basin has been investigated using X-ray diffraction, scanning electron microscopy, and high-resolution transmission electron microscop...
Abstract: The clay mineralogy of an oxisol-saprolite overlying serpentinite and underlying basalt was studied with different techniques to evaluate the clay mineral transformation that occurred and to...
Clay mineralogy (including illite crystallinity) was studied in Pennsylvanian synorogenic sediments (Atoka Formation) in the subsurface of the Arkoma Basin and the adjacent Ouachita thrust belt. Vitri...
The Upper Cretaceous (Maastrichtian) Whitemud Formation is a potentially commercial kaolin deposit located in southern Saskatchewan and southeastern Alberta. The Whitemud Formation contains a lower ka...
Clay mineral relative abundances in approximately 450 samples from cores recovered during ODP Leg 117 in the Arabian Sea have been used to examine the paleoclimatic, paleoenvironmental, and tectonic h...
Abstract: The mineralogy of the clay fraction was studied for soils and saprolite on two Blue Ridge Front mountain slopes. The clay fraction contained the weathering products of primary minerals in th...
Changes in hydraulic conductivity and clay dispersivity of clay-sand mixtures (four reference smectites and Fithian illite) as a function of concentration (0.01 M Cl and distilled water) and so...
Almost four decades of study of Desmoinesian strata of Middle Pennsylvanian age in south-central Iowa and north-central Missouri have provided the stratigraphic control required to test the variation ...
The chemical and mineralogical properties of six soils previously believed to be developed from coastal plain sediments were found to be significantly influenced by thin loess overlays and admixtures....
Clay Mineralogy of Andesite Saprolite     Clay Mineralogy  Andesite Saprolite       font style='font-size:12px;'> 2011/11/17
Clay mineral associations in saprolite of two andesites from the Cascade Range of northeastern California were determined. Sesquioxidic allophane with a high CEC delta value dominates the clay fractio...
