TL;DR: The Synchrotron X-ray Methods in Clay Science workshop as mentioned in this paper was held prior to the 11th International Clay Conference on Saturday, June 14, 1997, at Carleton University, Ottawa, Ontario, Canada.

TL;DR: These findings imply that, in addition to chemical speciation, a pH-dependent formation of montmorillonite crystallites with unexfoliated layers may be responsible both for the decreased OTC intercalation and for the increased binding on external sites, thus resulting in the different patterns of interstratification as a function of increasing pH.

TL;DR: In this paper, the effect of charge location on the hydration properties of two trioctahedral synthetic minerals: saponite and hectorite, was compared by determining the structural characteristics which were obtained by modelling XRD patterns.

TL;DR: In this paper, the upper half of a 1 m thick discontinuous bentonite bed interlaminated in the Lower Cenomanian sedimentary formations of the northern Aquitaine basin (France) was studied using X-ray diffraction patterns obtained from the <2 μm fraction in the Ca and K-saturated states.

TL;DR: In this paper, a combination of chemical analyses and of X-ray diffraction profile modeling on a series of experimentally self-aluminized samples aimed at an improved description of HI minerals and more especially of their interlayer crystal chemistry is presented.
