TLDR
In this article, it was verified that this irregularity was due to the interstratification of different types of crystalline layers, which is a phenomenon that was first observed on studying clay minerals by X-ray diffraction.Abstract:
Interstratification is a phenomenon that was first observed on studying clay minerals by X-ray diffraction. It was noted that the majority of them had basal reflections (001), which did not form a regular series. It was verified that this irregularity was due to the interstratification of different types of crystalline layers.read more

J. C. Hunziker,M. Frey,Norbert Clauer,R. D. Dallmeyer,H. Friedrichsen,W. Flehmig,K. Hochstrasser,P. Roggwiler,Hans Schwander +8 more
TL;DR: In this paper, 35 illite and muscovite concentrates extracted from Triassic and Permian claystones, shales, slates and phyllites along a cross-section from the diagenetic Alpine foreland (Tabular Jura and borehole samples beneath the Molasse Basin) to the anchi-and epimetamorphic Helvetic Zone of the Central Alps were extracted by microscopic, X-ray, infrared, Mossbauer, thermal (DTA and TG), wet chemical, electron microprobe, K-Ar,

Authigenic kaolin and illitic minerals during burial diagenesis of sandstones: a review
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.

Layer charge heterogeneity in vermiculites
TL;DR: In this article, the authors compared experimental basal spacings with dL/n-plots to determine the average charge density of 25 vermiculites and found that the high-charged vermicules (≥ 0.8 eq/(Si,Al)4O10) with paraffin-type interlayers follow a straight line in the dL /n plots.

Progressive Low-Grade Metamorphism of a Black Shale Formation, Central Swiss Alps, with Special Reference to Pyrophyllite and Margarite Bearing Assemblages
TL;DR: The unmetamorphosed equivalents of the regionally metamorphosed clays and marls that make up the Alpine Liassic black shale formation consist of illite, irregular mixed-layer illite/montmorillonite, chlorite, kaolinite, quartz, calcite, and dolomite, with accessory feldspars and organic material.

X‐Ray Interference in Partially Ordered Layer Lattices
TL;DR: In this paper, the x-ray interference is calculated for layer lattices in which the phase shifts between consecutive layers and the scattering powers of individual layers do not follow a strictly periodic arrangement.

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.

Iron Oxide Removal from Soils and Clays1
N. H. Aguilera,M. L. Jackson +1 more
TL;DR: In this article, a procedure is presented which employs sodium dithionite (Na2S2O4, hyposulfite, or "hydrosulfite") as the reductor, and 0.3 molar citrate with or without Fe-3 specific Versene as the chelating reagent.

Weathering Sequence of Clay-size Minerals in Soils and Sediments
TL;DR: In this paper, a general occurrence of interstratified X-amorphous zones in 2:1 layer silicates was found in soils and other deposits, accounting for their diffraction properties; internal surface; K, H₂O, and OH contents.
