Pedogenic Smectites in Podzols from Central Finland: An Analytical Electron Microscopy Study
Analytical Electron Microscopy Finland High-Resolution Transmission Electron Microscopy Podzols Smectites
2011/12/6
Abstract: Transmission electron microscopy (TEM) including high-resolution transmission electron microscopy (HRTEM) and analytical electron microscopy (AEM) were used to study the fine clay fraction (...
Pedogenic Formation of Kaolinite-Smectite Mixed Layers in a Soil Toposequence Developed from Basaltic Parent Material in Sardinia (Italy)
Basaltic Rock (Weathering) Kaolinite-Smectite Mixed Layers Sardinia Smectite-Layer Charge Soils
2011/12/7
Abstract: Formation of kaolinite-smectite (K-S) mixed layers in a soil toposequence developed from basaltic parent material was examined. The soil formed in a temperate climate with alternating dry an...

Beidellite High-charge Smectite Layers Illite-Smectite Mixed Layers Italy Smectite Soil Vertisol
2011/12/8
Abstract: The fine clay (<0.1 祄) fraction of a clayey soil (Vertisol) from Sardinia (Italy) was studied by means of X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, cation exch...
Pedogenic and groundwater processes in a closed Miocene basin(northern Spain)
Pedogenic Miocene basin Sepfilveda-Ayll6n Basin
2011/11/7
The Sepfilveda-Ayll6n Basin (SAB) was an episodically closed Miocene basin adjacent to the Tertiary Duero Basin (northern Spain). The sediments studied here represent a depositional system developed f...
Comparison of Pedogenic and Sedimentary Greigite by X-ray Diffraction and Mossbauer Spectroscopy
Greigite Mossbauer Sediment Soil XRD
2011/12/29
Greigites from a gley and a Tertiary sediment were investigated by X-ray diffraction and Mössbauer spectroscopy. The cell-edge length a of 9.8639 Å ± 0.0003 Å for the soil greigite wa...
Pedogenic Formation of Montmorillonite from A 2:1–2:2 Intergrade Clay Mineral
Pedogenic Formation Montmorillonite Intergrade Clay Mineral
2012/2/21
Montmorillonite was found to be the dominant clay mineral in surface horizons of certain soils of the North Carolina Coastal Plain whereas a 2:1–2:2 intergrade clay mineral was dominant in subjacent h...
