Clays and Clay Minerals (2016) 64 (4): 488–502.
... to the broad range of force-field models available, an important question to ask is which sets of parameters will best suit the molecular modeling of the organointercalated smectites? To answer this question, the structure of the ethylene glycol (EG)-smectite complex is used here as a testing model because...

... clays and is generally based on X-ray diffraction (XRD) patterns after specific treatments of the clay samples. Saturation with K or Mg followed by ethylene glycol (EG) solvation are classical methods used to identify high-charge smectite and vermiculite. These procedures have been applied to two...

...S. HILLIER; P. C. RYAN Abstract X-ray powder diffraction patterns of halloysite (7 Å) are characteristically altered following solvation with ethylene glycol. Some effect was first noted in the classic work of MacEwan but its value in the unequivocal identification of halloysite (7 Å) seems...

...Ludmila Dolar-Mantuani; Ray Laakso Abstract Rocks which contain significant amounts of swelling-type clay minerals disintegrate when they are exposed to drying and wetting or to freezing and thawing. The ethylene glycol immersion test is used as a standard test to simulate the breakdown of rocks...

American Mineralogist (1969) 54 (3-4): 562–567.
...Robert C. Reynolds, Jr. Abstract A study of the intensities of basal reflections from ethylene glycol monoethyl ether-montmorillonite indicates that the plane of symmetry of the aliphatic chain lies perpendicular to the clay oxygen surface. The complex appears to contain two layers, each of which...

American Mineralogist (1965) 50 (7-8): 990–1001.
...Robert C. Reynolds, Jr. Abstract Oriented aggregates of ethylene glycol-montmorillonite were studied by x -ray diffractometer methods. Basal reflections, through the 00 14, provided the basis for structural analysis by Fourier and trial and error methods. On the basis of the intensity data...

...Reinhard W. Hoffmann; G. W. Brindley Abstract The swelling of montmorillonite immersed in ethylene glycol or in glycerol has been used for many years to identify montmorillonite in mixtures of clay minerals. It is sometimes believed that montmorillo-nite has an ‘affinity’ for these compounds...

(a) Powder X-ray diagram of air-dried and ethylene-glycol-treated glaucony from core 57R. (b) Deconvoluted (001) peak at ~10 Å of ethylene-glycol-treated glaucony from core 57R. (c) Powder X-ray diagram of air-dried and ethylene-glycol-treated glaucony from core 52R. (d) Deconvoluted (001) peak at ~10 Å of ethylene-glycol-treated glaucony from core 52R. Theoretical curves (bold lines in deconvoluted diagrams), resulting from the sum of the deconvoluted peaks (blue, red, and orange lines), display good agreement with experimental diagrams. Red and orange peaks correspond to R3 illite(0.9)/smectite (see for more details Fig. 4a) and blue peak to smectite or smectite-rich R0 illite/smectite. (Color online.)

Air-dried (AD) and ethylene glycol (EG)-solvated XRD patterns of TS 01, TS 02, TS 03, TS 04, TS 05, and TS 06 from the Patala Formation. Comparison between AD and EG-solvated XRD patterns reveals the absence of discrete smectite and I-Sm phases. Detection of discrete illite indicates that the Patala Formation has entered the R3 illitization zone. Ilt – illite, Kln – kaolinite, Chl – chlorite, Qz – quartz, Ms – muscovite, Cal – calcite (Whitney and Evans, 2010).

Comparison of XRD traces of air-dried (black curves) and ethylene glycol-solvated (blue curves) samples from oriented mounts of the fine fraction of CB-01 samples. The sample names are reported on the right. The last number in the labels corresponds to the core depth in centimetres. Three climate groups are assigned according to CS-XRF data: dry, wet and transition. The samples display a greater smectite proportion (best observed in the 16.9 Å peaks of ethylene glycol-solvated samples) in the wet climate phase. Modified from Foerstner et al. (2018).
