Modelling of X-ray diffraction profiles: Investigation of defective lamellar structure crystal chemistry
TL;DR: In this paper, the basic concepts of such identification and review the literature to outline how our understanding of defective structures and mixed layers has improved over the last decade or so and to describe some of the new perspectives opened by this improvement.
Journal ArticleDOI
An empirical Scherrer equation for weakly swelling mixed-layer minerals, especially illite-smectite
TL;DR: The Scherrer equation as mentioned in this paper links the measured width of an X-ray diffraction peak (Scherrer width, SW) to the number of stacked cells in the direction normal to the diffracting planes.

X-ray Identification of Mixed-Layer Structures: Modelling of Diffraction Effects
Boris A. Sakharov,Bruno Lanson +1 more
TL;DR: In this paper, the theoretical concepts allowing the calculation of diffraction effects from mixed layer structures using the matrix formalism were described, and algorithms allowing a comprehensive determination of probability parameters required to describe layer stacking.

Vermiculitization of smectite interfaces and illite layer growth as a possible dual model for illite-smectite illitization in diagenetic environments : a synthesis
TL;DR: In this paper, a structural model for illite-smectite (I-S) from diagenetic environments is proposed, which accounts for the presence of three different layer types.
Clay minerals in the meuse-haute marne underground laboratory (france): possible influence of organic matter on clay mineral evolution
TL;DR: In this article, the authors used the multi-specimen method developed by Drits et al (1997a) and Sakharov et al. (1999) to detect a mixture of an unusually (?) illitic (~65% I) randomly interstratified I-exp (illite-expandable MLM) and of a discrete smectite, in addition to discrete illite, kaolinite and chlorite.

Mechanism of burial metamorphism of argillaceous sediment: 1. Mineralogical and chemical evidence
TL;DR: In this paper, a detailed mineralogical and chemical investigation of shale cuttings from a well (Case Western Reserve University Gulf Coast 6) in Oligocene-Miocene sediment of the Gulf Coast of the United States was made by x-ray diffraction.
Journal ArticleDOI
Clay Diagenesis in Wilcox Sandstones of Southwest Texas: Implications of Smectite Diagenesis on Sandstone Cementation
James R. Boles,Stephen G. Franks +1 more
TL;DR: In this paper, a diagenetic model is proposed which involves the breakdown of detrital K-feldspar and of some smectite layers in illite/smectite to convert other smectitite layers to illite.
Journal ArticleDOI
The Nature of Interlayering in Mixed-Layer Illite-Montmorillonites
TL;DR: In this paper, the authors investigated the interstratification of mixed-layer illite-montmorillonites by comparison of diffraction patterns with calculated one-dimensional diffraction profiles, taking into account the effects of particle size distribution, chemical composition, and convolution factors.

Eindimensionale Fehlordnung in Kristallen und ihr Einfluss auf die Röntgeninterferenzen. I. Berechnung des Fehlordnungsgrades aus den Röntgenintensitäten
TL;DR: In this paper, the authors developed a general theory of X-ray scattering by crystals showing order in two translation directions but disorder in the third direction, the treatments previously published having proved inadequate for the interpretation of some single-crystal observations of the author.
