TL;DR: In this article, a quantitative description of smectite hydration, based on the relative proportions of different layer types derived from the fitting of experimental X-ray diffraction (XRD) patterns recorded under controlled relative humidity (RH) conditions on Li-, Na-, K-, Mg-, Ca-, and Sr-saturated specimens, was studied.

TL;DR: In this paper, X-ray diffraction and Mn K-edge extended Xray absorption structure (EXAFS) spectroscopy were combined to elaborate a structural model for phyllomanganates (layer-type Mn oxides) lacking 3D ordering.

TL;DR: The diagenetic evolution of kaolin and illitic minerals in sandstones is described in this article, where the structural characterization of these minerals, the possible reaction pathways leading to their crystallization, and the origin of the fluids involved are discussed specifically.

TL;DR: In this article, a combination of X-ray diffraction, texture goniomom- etry, and powder and polarized extended Xray absorption fine structure (EXAFS) spectra were used to investigate quantitatively the speciation of Zn in soils contaminated by three smelters.

TL;DR: In this paper, the local structures of divalent Zn, Cu, and Pb sorbed on the phyllomanganate birnessite (Bi) have been studied by powder and polarized extended X-ray absorption fine structure (EXAFS) spectroscopy.
